This four port polarization maintaining optical circulator routes input light from input port to three different output ports in sequence. It has two types of route path, type A the traditional routing from port 1 to port 4; type B the full circle routing from port 1 to port 4 and then back to port 1.
This product features low insertion loss, high extinction ratio, and high isolation.
- High isolation and extinction ratio
- Low insertion loss
- Low cross talk
- High stability and reliability
- Epoxy-free optical path
- Fiber optical networks
- Dispersion compensation
- Polarization sensitive optical systems
