Isolator PBC/PBS (IPBC/IPBS)

The Isolator Polarization Beam Combiner/Splitter is a hybrid device that has functions of PBC/PBS and isolator in a single compact package. The IPBC/S is characterized with low insertion loss, high isolation, high return loss, high extinction ratio and excellent environmental stability and reliability. It is ideal choice for application in fiber amplifier, and optical communication systems where signal monitoring is required.
 
Key Features:
1.Low insertion loss
2.High extinction ratio
3.High isolation
4.Excellent stability and reliability

 

Applications:
1.Fiber lasers
2.Fiber amplifier
3.Fiber Sensors
4.Optical Communications

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

* For IPBS with working axis type 2, Insertion loss is for polarized light input.

* S=Single Stage, D=Dual Stage

* IL is 0.3dB (1310~1550nm) or 0.5dB (1064nm) higher, RL is 5dB lower and ER is 2dB lower for each connector added. The default connector key is aligned to slow axis.
