The 1310nm&1550nm 4 Port Polarization Insensitive Optical Circulator is a compact, high performance light-wave 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. This component provides high isolation, low insertion loss, and excellent environment stability. It can be used for wavelength add/drop, dispersion compensation and EDFA applications.

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.
