2000nm 3-port High Power SM Optical Circulator-15W

The 2000nm 3-port High Power SM Optical Circulator-30W is a compact, high performance light wave olarization independent component that routes incoming signals from Port 1 to Port 2, and incoming Port 2 signals to Port 3. So, fiber optic circulators act as signal routers, transmitting light from an input fiber to an output fiber, but directing light that returns along that output fiber to a third port. They are ideal for high power fiber laser and instrumentation applications.

Features

  • Low Insertion Loss
  • High Power Handling
  • High Isolation
  • PM and Non-PM are available
  • Fiber can be customized
  • High Reliability
  • Excellent Temperature Stability

Applications

  • High Power Fiber Lasers
  • High Power Fiber Amplifier
  • Pump Laser Source
  • Test and Measurement
  • Instrumentation

The 2000nm 3-port High Power SM Optical Circulator-30W is a compact, high performance light wave olarization independent component that routes incoming signals from Port 1 to Port 2, and incoming Port 2 signals to Port 3. So, fiber optic circulators act as signal routers, transmitting light from an input fiber to an output fiber, but directing light that returns along that output fiber to a third port. They perform a similar function as an isolator, protecting the input fiber from return power, but also allowing the rejected light to be employed.

The fiber optic circulator utilizes proprietary designs and metal bonding micro-optics packaging. They’re characterized with low insertion loss, high isolation, high power handling, high return loss, excellent environmental stability and reliability. They are ideal for high power fiber laser and instrumentation applications. It is widely used in combination with fiber gratings and other reflective components in WDM systems, wavelength add/drop, Fiber Amplifier, Fiber Laser application.

If you do not see a standard circulator that meets your needs, we welcome the opportunity to review your desired specification and quote a custom circulator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.

  1. Above specification are for device without connector and may change without notice.
  2. IL is 0.3 dB higher and RL is 5 dB lower for each connector added.
  3. The pass optical power is 2 W only for connector added, the connector is only used for performance testing at low power, higher power requires splicing fibers.
  4. If there is pulse application, please be sure to inform us of pulse energy and peak power.

Order information

P/N: HPPIOC-①-②-③-④-⑤-⑥-⑦

When you inquire, please provide the correct P/N number according to our ordering information and attach the appropriate description would be better. If need any connector, we do not recommend choosing a 250μm bare fiber pigtail. For high power applications, we recommend direct splicing without connectors.
