Product Overview of 4 Port Optical Circulator
Fiber Optical 4 Ports 1550nm Circulator For CATV System
Fiber Optical Circulator
4 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 3 port circulator, four port device has one additional bi-directional port. Thus, 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.
