1x2 1064nm/1310nm/1550nm Three Ports PM Fiber Circulator Slow Axis Alignment
The polarization-maintaining optical circulator is a three-port polarization-maintaining optical fiber device for the directional transmission of optical signals. The biggest feature is that the optical signal can only be transmitted in a specific direction, and it has a great difference in reverse application. The device has a very wide range of applications in the field of optical fiber sensing and coherent detection.
