500SCM01 1MRB200059/ C1MRB15004R0001 Star coupler module is an important part of optical fiber communication equipment, with specific functions and structural characteristics. The following is a detailed description of the star coupler module:
Definition:

500SCM01 1MRB200059/ C1MRB15004R0001 Star coupler is an n×m type coupler, which is used to combine the optical power input from n optical fibers and evenly distribute it to m optical fibers. Here n and m are not necessarily equal, so star couplers are often used as multiterminal splitters.

The 500SCM01 1MRB200059/ C1MRB15004R0001 Star coupler module can be extended in the manufacturing process to create multi-mode fiber couplers with more than 4 ports by fusion double cone forming technology. Multiple independent multimode fibers are twisted and fused with each other to make a star coupler. The coupler can be transmission type or reflection type. In a transmission star coupler, power is input to any port on one side of the coupler, and power is transmitted to all ports on the other side. Reflective star couplers then couple light from any port to all ports of the coupler3.

In addition, 500SCM01 1MRB200059/ C1MRB15004R0001 star coupler module also has passive and active points. Passive star couplers are characterized by high reliability and low cost, while active star couplers are very useful in implementing LAN, which can receive a signal from any transmitter, then convert the optical signal into a current signal, and amplify this signal current, and then use this current to drive the light source and re-generate the optical signal. Active star couplers also contain collision detection devices that prevent collisions between packets sent simultaneously by different terminals.3
