Project Description
1310&1550nm 3 port Polarization Insensitive Optical Circulator
The 1310&1550nm 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.

- Above specifications are for device without connector.
- For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower. Power transmits through the connector less than 2W.
- For high power applications, we will use heat sink package, contact DK Photonics for details.
- For high-power applications, IL and ISO will be slightly worse due to the heat absorbed by the Faraday plate and the temperature rise. But they are all within a reasonable range. For more information, please contact DKP.
