1064nm 4-port Polarization Maintaining Optical Circulator

The 1064nm 4-port Polarization Maintaining Optical Circulator(Fast axis blocked) is a compact, high performance lightwave component that routes incoming signals from Port 1 to Port 2, incoming Port 2 signals to Port 3, and incoming Port 3 signals to Port 4. It utilizes proprietary designs and metal bonding micro optics packaging. It provides low insertion loss, broad band high isolation, high extinction ratio, excellent temperature stability and optical path epoxy free. It can be used for wavelength add/drop, dispersion compensation and EDFA applications.

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 850nm to 21000nm.

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. The transmission optical path of A type is different from B type: Type A: 1 -> 2, 2 -> 3, 3 -> 4; Type B: 1 -> 2, 2 -> 3, 3 -> 4;4->1
  4. For this 1064nm Circulator, Due to high IL, it is recommended to use average power of <300mW for Type B and <100mW for Type A. If you need higher handle power, please look for our 1064nm High power Circulator.
  5. If there is pulse application, please be sure to inform us of pulse energy and peak power.
