GEZHI Photonics’ Four-port Optical Circulator is a special type of circulator that has one input (port 1), one output (port 4) and two common ports (port 2&3). The light goes through port 1 to port 2. At port 2, any incoming light is guided to port 3 as output, while all input from port 3 is guided to port 4 as output.

Compared to three-port circulator, four-port device has one additional bi-directional port. Hence, it can be used to construct more flexible or more complex optical fiber sub-systems, such as add/drop module, mux/demux module, multi-port bi-directional splitters, WDM optical router, etc.

Features:

• Low Back Reflection
• High Extinction Ratio
• Low Insertion Loss & High Return Loss

Application

• DWDM system
• Add-Drop Multiplexing
• Fiber Amplifier
• Fiber Sensor
• Chromatic Dispersion Compensation Devices
• Fiber Bragg Grating
