Project Description

1030nm 3-port Polarization Maintaining Optical Circulator(Both axis working)

The 1030nm polarization maintaining optical circulator is a compact, high performance lightwave 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.

DK Photonics offers a large selection of polarization insensitive or polarization maintaining 3-port/4-port optical circulator. These devices can handle powers rang from 300mW to 20W, and have center operating wavelengths ranging from 500nm to 2100nm.

If you do not see a standard Optical 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 specifications are for device without connector.
  2. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. The default connector key is aligned to slow axis.
  3. For this 1030nm Circulator, due to high IL, it is recommended to use average power of <100mW, If you need higher handle power, lower IL, please look for our 1030nm High power Circulator.
  4. If there is pulse application, please be sure to inform us of pulse energy and peak power.
