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.

Features

• High isolation and extinction ratio
• Low insertion loss
• Low cross talk
• High stability and reliability
• Epoxy-free optical path

Applications

• Fiber optical networks
• Dispersion compensation
• Polarization sensitive optical systems
