Isolator Polarization Beam Combiner/Splitter
|
(IPBC/IPBS Series)
The Isolator Polarization Beam Combiner/Splitter is a compact devices which provides both polarization beam
combining and optical isolation in one integrated component. The most common application is to combine the
light of two pump lasers into a single fiber to double the pump power to an Erbium-Doped Fiber Amplifier (EDFA)
or a Raman Amplifier. Due to IPBC/IPBS has extremely low insertion loss it can improve the amplifier performance.
