Polarization Beam Combiner/Splitter (PBC/PBS)

The Polarization Beam Combiner/Splitter is a micro-optic device that can combine two polarized light signals into one output fiber, or split one light into two polarized outputs with their polarization states orthogonal to each other. The typical configuration of PBC uses the two PM fiber for input and the SM fiber for output. It is ideal choice for application in EDFA, Raman amplifier, pump lasers, high speed communication systems and optical fiber sensors.


Key Features:

* Low insertion loss

* High extinction ratio

* Excellent stability and reliability

 

Applications:

* EDFA

* Raman amplifier

* Optical Communications

* Laboratory R&D

* For PBS with working axis type 2, Insertion loss is for polarized light input.* For PBS with working axis type 0, Insertion loss is for un-polarized light input;

* IL is 0.3dB (1310~1550nm) or 0.50dB (980~1060) or 0.80dB (780~850) or 1.50dB (630) higher, RL is 5dB lower and ER is 2dB (1310~1550nm, 980~1060nm) or 3dB (780~850nm, 630nm) lower for each connector added. The default connector key is aligned to slow axis
