CWDM vs DWDM: How to Choose the Right Option for Your Needs?

DWDM (Dense Wavelength Division Multiplexing) and CWDM (Coarse Wavelength Division Multiplexing) are two common technologies that are frequently taken into account while designing a reliable and effective optical network. Although multiple signals can be transmitted concurrently via optical fibers using both CWDM and DWDM, there are some key differences between the two technologies, including differences in cost, scalability, capacity, and distance.

Let’s examine the features of CWDM and DWDM in this blog post and see which is the best option for your unique network requirements.

CWDM

CWDM technology enables the multiplexing of multiple optical signals using different wavelengths.

Contrary to DWDM, CWDM operates with a larger channel spacing over a wider wavelength range (typically 20nm). CWDM is a workable substitute for applications requiring a shorter reach because of the simpler implementation and lower cost of the optical components due to the larger spacing.

A total capacity of 180 Gbps is possible with CWDM by supporting up to 18 channels, each of which may carry data at up to 10 Gbps. It is most suited for deployments in environments with short transmission distances, such as urban or college networks.

DWDM

In contrast to CWDM, DWDM technology has a substantially higher capacity and longer transmission ranges.

DWDM uses closely spaced wavelengths to carry several signals concurrently over a single optical wire (typically 0.8nm or 0.4nm apart). Long-haul and high-capacity applications benefit from DWDM’s ability to fit a large number of channels into the limited amount of spectrum that is available.

DWDM systems are capable of supporting terabit-level capabilities by supporting hundreds of channels, each with data speeds ranging from 10 Gbps to 400 Gbps. For extensive deployments covering hundreds or thousands of kilometers, such as national or international backbones, it is the preferable option.

Factors to Think About When Choosing Between CWDM and DWDM

1.    Scalability and Capacity:

Analyze the present and foreseeable capacity needs for your network.

  • Compared to CWDM, DWDM offers more scalability if you need to accommodate a large number of channels and data speeds.

2.    Transmission Distance:

Think about how far apart your network nodes are.

  • CWDM is appropriate if your network only spans a few short distances.
  • DWDM is the preferred option for long-haul applications when transmission distances reach hundreds or thousands of kilometers.

3.    Price:

The budget is a key factor in decision-making.

  • Because of its less complicated components and larger channel spacing, CWDM provides a practical solution for shorter distances.
  • Although DWDM tends to be more expensive due to its larger capacity and complexity, it offers more scalability.

4.    Flexibility:

Find out how flexible your network needs to be.

  • CWDM is appropriate for dynamic environments because it makes adding or removing channels simple.
  • DWDM is a reliable and stable solution for networks with known growth patterns, despite its reduced flexibility.

Which One to Choose?

Capacity, transmission distance, cost, and flexibility are some of the factors affecting the choice between CWDM and DWDM. While DWDM has a greater reach and higher capacity, making it suited for large-scale deployments, CWDM is more affordable for shorter distances with lesser capacity requirements. To make an informed choice, carefully assess the requirements of your network and take into account the elements covered in this post. Consultation with optical network specialists can offer helpful insights into choosing the best technology for your unique needs.

Top Reasons to Choose DWDM Mux/Demux

With the internet, there has been a large influx of data, and while this is good for a business as data helps in many ways, it is a challenge to handle big data. Highly efficient and capable data transmission speed seems inevitable.

To solve the paradox of increasing bandwidth with less spending, DWDM Mux/Demux is the perfect choice. This is designed to be capable of transporting even extremely large capacity of data traffic in telecom networks. And all that with high level of efficiency and a greater speed!

A great solution to the bandwidth explosion from the access network!

What is WDM and how does it work?

WDM which stands for wavelength division multiplexing is the process whereby various light waves are multiplexed into one single signal that can be transmitted through an optical fiber.

But the light signals indexed into single signal split into different light waves at the receiver end. There are versions: coarse wavelength division nultiplexing (CWDM) and dense wavelength division multiplexing (DWDM).

And the ‘wavelength steps between the channels’ is the main deference between these WDMs.  For example, while it is 20nm (course for CWDM, for DWDM this is typically 0.8nm (dense).

But here we will discuss the latter, DWDM technology: how it works, its benefits and also the drawbacks if there are any.

DWDM technology works to integrate multiple signals at different wavelengths over the same fiber. This technology is the result of long efforts to find a better solution to the growing need for efficient and capable data transmission. It is uses different colors (wavelength) which are integrated into a device called Mux/Demux which stands for multiplexer/demultiplexer. These devices are meant to integrate and segregate the signals respectively. Mux is used at the feeding end while the Demux on the receiving end.

As the function of Mux is to select one of several input signals to send to the output, it is also called a data selector. It acts as a multiple-input and single-output switch which sends optical signals at high speed over a single fiber optic cable. It eliminates the need for using several devices for different input signals. With Mux, sending a large amount of data over the network at a higher speed is now feasible.

On the contrary, Demux that has one input and more than one out-puts can send one single input signal to one of many devices. Its main purchase is to receive a signal comprising multiple optical frequencies and separates it into its frequency components.

DWDM Mux/Demux modules provide the advantages of DWDM technology in a fully passive solution. They are perfect for long form transmission. In fact, they have a long list of benefits provided you choose the right one for you.  To make the most, you should buy your DWDM Mux/Demux from a reputed supplier like DK Photonics which is known for providing a wide range of high quality optical passive components in China.

Know All about the DWDM and its Utilization and Significance

WDM is the abbreviation for Wavelength Division Multiplexing, it is a popular technology used in currently fiber optic communication systems. By WDM, we can split a number of optical lights in an optic fiber into a number of discrete wavelengths. Each wavelength can be considered to an independent channel running at a special data rate of 5Gbit/s, 10Gbit/s, 40Gbit/s or even 100Gbit/s. If the light in the fiber is split into 16 channels, and each channel running at 40Gbit/s, the total data transmission rate will be 640Gbit/s. In effect, this means maximized use of a single fiber optic to transmit and receive a large number of signals, minimizing costs for telecom companies. WDM technology is also the working principle of optical amplifiers, multiplexers, and demultiplexers. Next, I will give a separate introduction about WDM/CWDM/DWDM technologies.

DWDM and Conventional WDM

DWDM stands for Dense Wavelength Division Multiplexing. It means the divided wavelength channels are very narrow and close to each other. It is widely used for the 1550nm band so as to leverage the capabilities of EDFA (Erbium Doped Fiber Amplifiers), which are effective for wavelengths between approximately 1525-1565 nm (C band), or 1570-1610 nm (L band). Conventional WDM Conventional WDM uses the 3rd transmission window with a wavelength of 1550nm, accommodating up to 8 channels. DWDM basically is the same however along with the higher density channel. An ultra-dense WDM is capable enough to work at the spacing of just 12.5 GHz, allowing some more channels.

CWDM

CWDM refer to Course wavelength division multiplexing, in CWDM technology, it shared the fact that the choice of channel spacing and frequency stability which is the EDFA could not use. There is an increase in channel space; it cannot be used in EDFA. One basic meaning for the CWDM is two (or more) signals are multiplexed onto the single fiber, where one signal was into the 1550 nm band, and then another one into the 1310 nm band. Currently, there is an increase in the channel space. This means the need for less sophisticated and less costly transceivers devices. Working into the similar window of 1550 nm as well as making the utilization of OH-free silica fibers, the maximum efficiencies are gained into the channels 31, 49, 51, 53, 55, 57, 59 and 61 utilizing the wavelengths from 1270 nm through 1610 nm along with the channel spacing of 20 nm. CWDM devices are commonly used in fewer precision optics and lower cost, un-cooled lasers with lower maintenance requirements? Compared with DWDM and Conventional WDM, CWDM is much more cost-effective and less power consumption of laser devices.

Currently, kinds of related CWDM MUX/DEMUX or DWDM MUX/DEMUX or optical amplifiers are available in the market. Networking solutions provider is the right ones to ask for guidance for use of CWDM, DWDM or WDM technology. Choosing the right one means the correct, integrated devices for error-free high-speed data transmission over fiber optic networks. Cost-effective CWDM solutions with optimized performance and built-in expansion capabilities are available from a host of online network solution companies. Choosing the most experienced one to get the reliable CWDM solution is critical.

All Information You Must Keep in Mind Related to the CWDM Mux/Demux

The CWDM strategy multiplexes optical flags together on one single fiber. To accomplish this it utilizes distinctive hues (wavelengths) which are joined in a MUX. The gadget where the optical signs are multiplexed and de-multiplexed is known as a MUX or a fiber optical multiplexer or a CWDM multiplexer. Much of the time these MUXES are aloof so no power is required; henceforth the interim between disappointments is around 500 years.

All optical transmission is finished by double filaments where one fiber is transporting information from east to west and the other west to east. This double capacity is conceivable in light of the fact that one MUX has both a multiplexer and a de-multiplexer. There are two gauges for multiplexing: CWDM and DWDM. The principal distinction is the wavelength ventures between the channels: for CWDM this is 20nm (course) and for DWDM this is regularly 0.8nm (thick). CWDM has 18 wavelengths from 1610 to 1270 with ventures of 20nm.

The main eight wavelengths (1610-1470) are the most utilized and furthermore, are not influenced by what is alluded to as “the waterpark”. This waterpark causes high constriction from wavelengths 1370-1410nm on old kinds of filaments. Strong Optics offers the Passive CWDM MUX in 8 port and 18 ports and we additionally have the full scope of CWDM 1G (24dB/32dB/37dB) and SFP+/XFP 10G ER/ZR optics in stock. The greater part of our CWDM MUXES has the MUX and DEMUX inside and arrives in a 19-inch suspension with rack mounts.

By utilizing inactive multiplexers, a few optical channels of various wavelengths can be joined, which will enable different services to the transmitted together by means of fiber without obstruction. What makes this concept is the way that diverse light hues (wavelengths) don’t influence each other. For transmission, light hues are multiplexed onto a fiber utilizing a wavelength-particular channel (multiplexing). At the other (getting) end of the line, the wavelengths are separated once more, or rather, demultiplexed. Henceforth, any transmission line comprises of a multiplexer and a demultiplexer.

The inactive multiplexer and demultiplexer modules are working with the CWDM matrix concurring ITU G.694.2 standard. The multiplexer/demultiplexer rack modules are a piece of a wide item scope of utilitarian modules for the establishment in particular rack frameworks from MICROSENS. Notwithstanding work area lodgings, clients can choose a 19″ undercarriage with up to 12 openings. When utilizing multi-opening body, the converter might be joined with some other modules from the Enterprise Access family. What’s more, the MICROSENS item portfolio offers dynamic converters for optical or electrical/optical adjustment of information channels to the suitable wavelengths and required reaches.

Utilizing WDM as transmission innovation, organize administrators can fabricate a framework that might be extended relying upon require. What’s more, the limits in all sub-territories of the system are expandable. This speaks to leeway no other innovation can give. Utilizing latent multiplexers is of enthusiasm for link organizes administrators, as well. This innovation will permit giving extra services, for example, joining bi-directional information services with uni-directional TV transmission with no issue, while utilizing the current foundation.

CWDM frameworks have channels at wavelengths divided 20 nanometers (nm) separated, contrasted and 0.4 nm dispersing for DWDM. This permits the utilization of minimal effort, uncooled lasers for CWDM. In a common CWDM framework, laser emissions happen on eight channels at eight characterized wavelengths: 1610 nm, 1590 nm, 1570 nm, 1550 nm, 1530 nm, 1510 nm, 1490 nm, and 1470 nm. However, up to 18 unique channels are permitted, with wavelengths ranging down to 1270 nm. The energy from the lasers in a CWDM framework is spread out over a larger range of wavelengths than is the energy from the lasers in a DWDM framework. The tolerance (degree of wavelength imprecision or variability) in a CWDM laser is up to ± 3 nm, while in a DWDM laser the tolerance is substantially more tightly. On account of the utilization of lasers with lower precision, a CWDM framework is more affordable and consumes less power than a DWDM framework. Be that as it may, the greatest realizable separation between nodes is littler with CWDM.
