Huawei says it has collaborated with Russian service provider Rostelecom to develop floor distribution boxes (FDBs) for use in Rostelecom’s flexible fiber to the home (FTTH) deployments. The FDBs will help improve the efficiency of the operator’s FTTH deployments, particularly in sparsely populated areas, Huawei says.
Rostelecom is under a mandate from the Russian government to connect 13 million CWDM Module users by 2015, Huawei says. This task is complicated by the fact that much of the operator’s footprint covers rural areas.
To improve deployment efficiency, Huawei says it recommended what it calls “the thin-covered network deployment model.” According to the model, fiber-optic networks are constructed to user access points and the FDBs, the latter of which are used as the interface between the outside plant and the inside plant. As the network expands and more users are connected, pre-made drop cables can be used for plug-and-play, quick service provisioning.
The customized FDBs were designed for success-based deployment. Rostelecom can deploy FDBs that provide access to a single user, then add connections as many as four or eight users as take rates improve. Technicians can complete the expansion in one minute without the use of tools, Huawei says.
Huawei and Rostelecom will further collaborate on other network elements, including the closure, optical splitter, and fiber distribution terminal (FDT), the technology provider added.

According to ElectroniCast, optical isolator value in Telecommunications is forecast to increase 19.6% this year…
Aptos, California (USA) – April 29, 2014 —ElectroniCast Consultants, a leading market research & technology forecast consultancy addressing the fiber optics communications industry, today announced the release of a new market forecastof the global consumption of optical isolators in optical communication and specialty applications.
According to ElectroniCast, the worldwide optical isolator consumption was led by Telecommunication applications in 2013 with a 70 percent market share or $349.7 million, and is forecasted to increase 19.6 percent in value to $418.2 million this year (2014). Market forecast data in this study report refers to consumption (use) for a particular calendar year; therefore, this data is not cumulative data.
Optical isolators are devices that allow light to be transmitted in only one direction. They are most often used to prevent any light from reflecting back down the optical fiber, as this light would enter the source and cause backscattering and feedback problems. This is especially important for high data rate transceivers and transponders, or those devices requiring long span lengths between transceiver pairs. Optical feedback degrades signal-to-noise ratio and consequently bit-error rate.
“Continuing demand for upgrading communication networks to accommodate rapidly increasing bandwidth requirements will drive the steady consumption of optical fiber links. Optical isolators are used in with high-speed transmitters that are required to transmit longer distances and/or multiple wavelength transmitters,” stated Stephen Montgomery, Director of the Fiber Optics Components group at ElectroniCast Consultants.
Optical isolators are not widely used in Private Enterprise applications; however, worldwide use of fiber optic isolators in Cable TV controlled device deployments are forecast to grow significantly in value at an annual rate of 8.8 percent (2013-2018), as optical fiber is deployed closer to the home driven by multi-media applications.
Optical isolator units are used in a variety of Military/Aerospace applications requiring rigorous testing and harsh environment fiber optic (HEFO) certification to ensure reliability and performance. Laser-based fiber optic technology incorporating optical isolators are used in a wide variety of air, sea, ground, and space applications.
A major user-group within the Specialty application category is Laboratory/R&D. Optical isolators are used for noise reduction, medical imaging, pulse selection for mode locked lasers, sensing, regeneration switches, disc master, optical trapping, phase shifters, frequency modulation spectroscopy and general shuttering. The optical isolators are also used in sensing for industrial, structures and other many other communication product-oriented manufacturing/test/R&D uses.
“During the forecast period (2013-2018), bandwidth expansion demands will push for new network links, incorporating Metro Core, Metro/Access, Long Haul, Optical Fiber Amplifiers, WDM, OADM and other system-based deployments, which incorporate optical isolators,” Montgomery added.
The American region held the lead in terms of relative market share consumption value of optical isolators in 2013, with nearly 43.4 percent; however the American region is forecast to increase at a slower rate compared to the other regions (2013-2018). The Asia Pacific region (APAC) is forecast to increase in worldwide market share from 39.7 percent in 2013 to with 53.7 percent in 2018. The Europe, Middle East, African region (EMEA) is forecast to remain in the third-place position, however, increase at a faster annual pace versus the American region.
According to ElectroniCast, the American Region leads optical isolator consumption value…

A fiber-optic multiplexer is a device that processes two or more light signals through a single optical fiber, in order to increase the amount of information that can be carried through a network. Light wavelengths are narrow beams that ricochet through reflective optical tubing, sometimes over long distances, to provide instantaneous electronic signal processing at the speed of light. Multiplexers work by increasing a fiber’s transmission capacity using different techniques and light source technologies. When the signal arrives at its destination, a demultiplexer separates the data streams. Using a multiplexer also allows data to be sent farther, more securely, and with less electromagnetic and radio frequency interference.
16CH CWDM
Also known as a mux, the fiber-optic multiplexer saves time and cost by squeezing more information through the optical network pathway. It is possible to split signals by varying the schedule or period of each transmission. Time Division Multiplexing (TDM) combines multiple signals by rapidly alternating between them so that only one is transmitting at any given time. Statistical Time Division Multiplexing (STDM) assigns each signal a specific time slot in order to optimize bandwidth usage. Further techniques include divisions of wavelength and frequency.
Wavelength Division Multiplexing (WDM) utilizes the total available pass band of an optical fiber. It assigns individual information streams different wavelengths, or portions of the electromagnetic spectrum. Similarly, Frequency Division Multiplexing (FDM) assigns each signal a different frequency. Carrier frequencies contain the signal while unused guard frequencies provide buffering to reduce interference. This helps minimize audible and visual noise and preserves the integrity of the original signal throughout the network.
Fiber-optic multiplexer technology serves single-mode and multimode optical fibers with multichannel rack mount or standalone units. This makes mixing channels with different configurations possible for a range of interface combinations. These devices provide stronger, more reliable transmissions in areas that have a lot of electromagnetic, radio frequency, or lightning interference.
As technology improves and information needs grow to fill the capacities of existing networks, equipment such as the fiber-optic multiplexer lessens the need to upgrade the fiber-optic infrastructure itself. Multiplexers permit new configurations of transmission protocols by increasing the amount of wavelengths or frequencies of light signals. By upgrading repeaters and terminal equipment, existing network transmission capacity can expand with demand.
Used by cellular carriers, Internet service providers, public utilities, and businesses, fiber-optic multiplexer technology extends the reach and power of telecommunications technologies. Network management systems allow for system service and maintenance, and provide for security, fault management, and system configuration. With advantages like lower costs and longer life expectancies, current fiber-optical networks are aided by improvements in multiplexing technology, and may provide light speed data transmission well into the future.

According to ElectroniCast, the worldwide value of FSO link devices in stationary non-military/aerospace applications was $33.49 million in 2013…
Aptos, CA (USA) – January 24, 2014 —ElectroniCast Consultants, a leading market research consultancy, today announced the release of a report presenting their market analysis and forecast of Free Space Optics (FSO) communication links used in non-military/aerospace applications.
The global consumption of fixed-location (stationary) Transmitter/Receiver (T/R) links (pairs) used in non-military/ aerospace Free Space Optic system equipment was $33.49 million in 2013, up 11 percent from $29.83 million in 2012. Free Space Optic (FSO) Transmitters and Receivers (pairs) used in link equipment with a range capability of less than 500 meters or less led in relative market share in 2013 with a global consumption value of $23.06 million.
According to the Free Space Optics Global Market Forecast & Analysis (January 2014), FSO is a line-of-sight (LOS) technology that uses directed laser beams, which provide optical bandwidth Transmitters and Receivers to link voice, video, and data intelligent transfer. A single FSO link product (from point A to point B) often may incorporate multiple transmitters along with receiver/s to ensure adequate performance, in case of interference.
Free Space Optic communication links can be installed along railroad/subway tracks, tunnels, airport terminals, parking lot/structures or other major un-obstructed right-of-way (ROW); outdoors on building rooftops (building-to-building and/or campus), exterior walls, towers, indoors (aimed out a window), or any combination; however, a direct line-of-sight and appropriate distance are required to enable a Transmitter/Receiver Link between two points (point-to-point).
FSO-based products accommodate Ethernet-based protocols, SONET/SDH, ATM, FDDI and other standard and proprietary protocols. Products can be used for metropolitan (Metro) network extension; DWDM services, access/last mile, wireless backhaul, disaster recovery (testing and communications), storage area networks (SANs) and LAN/first mile/FTTx, and an almost endless list of other solutions.
The increase in the consumption of FSO links in the America region will be attributed to not only continued upgrades and network facilitation in the United States and Canada, but partly from the accelerating economic growth of major cities in Latin America. Other market dynamics in the American region are increases in communication links needed for growing infrastructures, such as mass transit, security systems, broadcast and telecommunications.
European inner-city urban areas typically are difficult for wire-lines, including optical fiber cable installations; therefore, this fact promotes FSO or other wireless solutions. The APAC region has advanced communication technology deployed especially in Japan; however, other countries, such as Australia, China and India, are not as advanced in campus-wide and metropolitan optical communication deployment.
The APAC region has rapidly expanding market opportunities and therefore, our forecast shows the region with the fastest growth (2013-2019), with the region taking over the leadership position later on in the forecast period.
According to ElectroniCast, the APAC region is forecast to eventually take the lead in terms of relative market share of non-military/aerospace FSO-Links…

According to ElectroniCast, the combined use of Continuous Distributed and Point fiber optics sensors will reach $4.33 Billion in 2018…
Aptos, CA (USA) – February 14, 2014 —ElectroniCast Consultants, a leading market/technology forecast consultancy, today announced the release of their market forecast and analysis of the global consumption Fiber Optic Point Sensors and Continuous Distributed Fiber Optics Sensor systems.
According to ElectroniCast, the consumption value is forecast to increase at an impressive 18% per year from $1.89 billion in 2013 to $4.33 billion in 2018. Market forecast data refers to consumption for a particular calendar year; therefore, this data is not cumulative data.
Continuous Distributed fiber optic sensor systems involve the optic fiber with the sensors embedded with the fiber. ElectroniCast counts each Point fiber optic sensor as one unit; however, the volume of Distributed Continuous fiber optic sensors is based on a complete optical fiber line and associated other components, which are defined as a system.
The use of Distributed Continuous fiber optic sensors in the Military/Aerospace/Security application category maintains the lead in 2014, followed by the Petrochemical/ Energy sector. The Civil Engineering/Construction sector, which includes continuous fiber sensors used in Structural Health Monitoring (SHM) as well as other concerns in buildings, bridges, tunnels, towers, and other structures, is also forecast for strong growth. Inspection and quality control frequently constitute the largest portion of production costs for many industries.
“There is a growing need for improved measurement solutions, which offer higher precision, speed and accuracy and provide better in-process measurement of moving objects, resulting in lower costs for better products. Relatively speaking, the Manufacturing/ Factory segment tends to favor point sensors instead of distributed fiber systems,” stated Stephen Montgomery, Director of the Fiber Optics Components group at ElectroniCast Consultants.
“The Biomedical/ Science sector is a relatively minor user of Distributed Continuous fiber optic sensors, in terms of consumption value, since the length of optical fiber is (very) short versus the other applications; therefore the average selling prices for the distributed continuous fiber optic sensor systems are low compared to the larger (longer length of optical fiber) distributed continuous fiber optic sensor systems used in other applications. The consumption value of Distributed Continuous fiber optic sensor systems is forecast to grow at 23% per year from $1.099 billion in 2013 to $3.096 billion in the year 2018,” Montgomery added.

Fiber Media Converters in Private DatacomMarket Forecast (March 2014)
According to ElectroniCast, the global use of fiber media converters in private datacom networks is expected to reach $1.29 billion in 2014…
Aptos, CA (USA) – March 20, 2014 —ElectroniCast Consultants, a leader in fiber optic market research, announced the release of a new market analysis of the worldwide use of fiber optic / Fiber media converters in private data communications. A fiber media converter is a networking device that makes it possible to connect two dissimilar media types such as copper with fiber optic cabling, as well as (different) fiber-to-fiber (F2F), such as multimode to single mode optical fiber.
The worldwide value for selected fiber media converters used in private datacom networks reached $1.07 billion in 2013. The consumption value is forecast increase with strongly rising quantity growth partially offset by declining average prices.
The EMEA and the APAC regions are forecast for double-digit consumption value growth during the timeline covered in this study (2013-2018); however, the American region’s growth is forecast to “flatten” and eventually turn to negative. The worldwide use of private datacom fiber media converters, which are specified in the ElectroniCast market study, is forecast to peak at $1.646 billion in 2017, before slipping to $1.628 billion in 2018.
“The fiber media converters researched in this market study are typically used within an existing Private Enterprise Data Centers (DCs) and Local Area Networks (LANs), as well as other non-public data communication links. They are often used to connect newer 100-Mbps, Gigabit Ethernet, 10G, or other equipment in existing networks, which are generally (copper-based) 10BASE-T, 100BASE-T, or a mixture of both,” stated Stephen Montgomery, Director of the Fiber Optics Components group at ElectroniCast Consultants.
“Several factors make the conversion from copper to optical fiber a good choice, such as – longer link lengths in campuses and industrial plants; resistance to electromagnetic and radio-frequency interference (EMI/RFI) may be necessary; and wider bandwidth capability, just to point-out a few examples,” Montgomery added.
The strong user demand for greater bandwidth and increased interconnectivity to the desktop, throughout the buildings, campuses, from LAN-to-LAN (Metropolitan Area Network – MAN) continues in 2014.
This is matched by rapidly growing demand for global broadband interconnectivity. Interactive multimedia terminals, triple play (voice, video and data), quadruple-play (adding mobility as a communications function to the network), and numerous other dynamics/ applications, continuing bring rapid access to massive databases, which increase productivity while providing rapid ROI (return on investment).
Such expanded capability, however, must often be obtained without making the current network elements obsolete. Local area network (LAN) applications illustrate this trend. LANs are becoming larger and more complex. Reconfiguration, relocation, and extension of LANs are occurring more frequently, due to organization restructuring, advances in computer usage, and the trend toward decentralized computing.
These changes to LAN cabling represent a major ongoing operational expense and a disruption of work for many companies (enterprises). For example, adding capabilities often requires that network administrators upgrade their existing LANs to another media type: for example, copper-to-fiber, multimode-to-singlemode fiber, or even singlemode –to- different types of singlemode optical fiber (note: copper-to-copper conversion is not covered in the study). By using media converters, the network administrator can achieve these upgrades inexpensively.
According to ElectroniCast, the global use of fiber media converters in private datacom reached $1.07 billion in 2013 and is forecast to peak at $1.646 billion in 2017, before slipping to $1.628 billion in 2018.

WDM-PON provides the dedicated bandwidth of a point-to-point network and the fiber sharing inherent in PONs. The architecture is somewhat similar to that of EPON and GPON; instead of the power-splitter approach used in TDM-PON architectures, WDM-PON uses an arrayedwaveguidegrating (AWG) filter that separates the wavelengths for individual delivery to the subscriber ONUs (see Figure 1).
A simple, plug-and-play implementation is based on wavelength-locked or tunable lasers. Self-tuning “colorless” ONUs can be used at the subscriber sites to simplify inventory and spare-part handling. Colorless optics not only simplify operations, but also reduce deployment costs, since they don’t need the expensive wavelength-stability components that traditional fixed and tunable optics require. There are multiple approaches to the colorless ONU technology.
In one approach, the wavelength of the ONU transmitter is controlled by injection of a “seed” signal into the transmitter (e.g., a wavelength-locked Fabry-Perot laser or reflective semiconductor optical amplifier). The seed signal injected into the transmitter could come from broadband ASE light sliced through the filters in the system or from a DFB laser array. In a self-seeding version of this approach, the seed light is provided by feedback of broadband light from the transmitter itself. The passive filtering of the seed light in the remote node determines the wavelength of the ONU transmitter.
In a different approach, the colorless ONU contains a singlemode optic coupler wavelength-tunable laser, which is able to tune to the appropriate wavelength that matches the remote node filter port.
Below 10-Gbps channel bit rates, the injection-seeded method provides a cost-efficient approach. As an example, a wavelength-locked Fabry-Perot transmitter can be integrated into an MSA SFP pluggable form-factor module, which enables the use of third-party CPE devices. A modified EDFA gain block in a 70×90 MSA form factor could be used to generate the broadband ASE light that’s used as a seed signal in the system.
At 10-Gbps bit rates, tunable-laser technology offers an alternative to the injection-seeded approach. The tunable-laser technology developed for the metro/long-haul market has matured significantly over the past couple of years and is able to give a good cost-per-bit ratio when high capacity is needed.
If the WDM-PON system is properly designed, then it’s possible to mix different transmission technologies. By following certain design rules during the installation of the WDM-PON system, it’s possible to allow step-wise channel upgrades to higher bit rates when the demand arises. These design rules ensure that channel OSNR requirements will be met in the presence of reflections and that inter-channel crosstalk is avoided. The result is an open and flexible access network that can support many applications and services over the same infrastructure. WDM-PON thus becomes an optical option for the access network as and where it makes sense.
Given its ability to help service providers cope with current bandwidth demands as well as the next potential broadband access bottleneck, WDM-PON/ 100GHz DWDM Moduleis becoming an important technology to consider in terms of its benefits and market timing. As with any emerging technology, service providers need to consider the optimal strategy for initial deployment of WDM-PON. That includes how they could use WDM-PON for additional network applications as the technology matures and its costs come down.
WDM-PON technology
FIGURE 2. Architectural scenario explored in the collaboration between Transmode and Deutsche Telekom Hochschule für Telekommunikation.
The latest generations of WDM-PON systems are now gaining traction with operators around the globe for field deployment, lab trials, and evaluations. It’s clearly the early stage of WDM-PON deployments, but progress has started and 2014 looks to be a pivotal year for the technology.
Many industry analysts believe that the increasing requirements for bandwidth scalability, quality of service, and support of the emerging traffic patterns required by video and broadcast standards will make copper networks insufficient for many high-bandwidth services in the future. Fiber availability is not universal, and the economics of new fiber deployments are often challenging; nevertheless, fiber will undoubtedly push deeper into access networks to support business services, mobile backhaul/fronthaul, multitenant buildings/fiber to the cabinet, and in some cases fiber to the home (FTTH), too. Yet today‘s fiber-based approaches, including TDM-PON/PLC Splitterand active point-to-point Ethernet, probably won’t meet the likely requirements of the next generation of bandwidth-intensive traffic, either.
WDM-PON is a passive optical networking approach — currently being developed by several companies — that can be used to more adequately address these challenges over fiber-based networks. A WDM-PON design can be used to separate optical-network units (ONUs) into several virtual point-to-point connections over the same physical infrastructure, a feature that enables efficient use of fiber compared to point-to-point Ethernet and offers lower latency than TDM-based approaches. A notable advantage of this approach is the combination of high capacity per user, high security, and longer optical reach. WDM-PON therefore is highly suitable for applications such as mobile backhaul or business Ethernet service provision.
Thus WDM-PON is poised to become the disruptive next generation access architecture. It will enable high-speed access for businesses, mobile backhaul, and eventually FTTH. WDM-PON also will enable operators to build converged networks and consolidate existing access networks, including potentially eliminating central offices to reduce cost while boosting performance.
There are several types of WDM-PON systems under development. They all have in common the use of passive, temperature-hardened DWDM optical filters in the remote node and colorless ONUs.

According to the ElectroniCast market study, the consumption value of component-level (compact device) PLC splitters reached $529.6 million in 2013. PLC splitters will continue to contribute an important role in Fiber to the Home (FTTH) networks by allowing a single passive optical network (PON) interface to be shared among many subscribers. PLC splitters are available in compact sizes; therefore, they can be used in aerial apparatus, pedestals or in-ground as well as rack mount or other module-based value-added product. Installation is simple using a variety of connector types or fusion splicing.
“The PON-based Fiber-to-the-Home network application dominates the worldwide PLC splitter consumption value in 2014,” stated Stephen Montgomery, Director of the Fiber Optics Components group at ElectroniCast Consultants.
“The American region is forecast for flat annual growth (just over 1%); however, the EMEA region is set for 7% per year and the APAC region is forecast to increase at 15% per year, for the component-level PLC splitters, during the 2013-2018 timeframe cover by the ElectroniCast study,” Montgomery added.
