Project Description

1064nm 3 port Polarization Insensitive Optical Circulator

The 1064nm 3 port Polarization Insensitive Optical Circulator is a compact, high performance light-wave 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. It’s a compact, high performance component, with high isolation, low insertion loss, low PDL, high stability and reliability. It is widely used in combination with fiber gratings and other reflective components in DWDM systems, wavelength add/drop, high speed systems, bi-direction communication systems, dispersion compensation, EDFA application and optical time domain reflectometer (OTDR) measurements.

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
  3. For this 1064nm Circulator, due to high IL, it is recommended to use average power of <300mW, If you need higher handle power, lower IL, please look for our 1064nm TGG High power Circulator.
  4. If there is pulse application, please be sure to inform us of pulse energy and peak power.
