PM Coupler

As general, PM coupler is made on the technology of fusion & Tapering. It works at 1310nm or 1550nm, with this configuration of

1x2 and 2x2. It is designed by Panda 125/250um PM fiber, which is possible to with connector on request. This coupling ratio is

covering 50/50， 20/80，30/70，40/60 and etc. Its E.R is assured 20dB more.

Below is its application,

Optical amplifier

Power Monitoring

Coherent communication

Fiber sensors

Fiber gyroscope

Also this PM coupler is made on filter type, which is fast-axis blocked or both slow and fast axis working

as axis alignment.
