2x2 Polarization Beam Combiner/Splitter
|
(DPBC/DPBS Series)
The Dual Polarization Beam Combiner/Splitter, 2x2 PBC/S, is a compact high performance lightwave component that
combines or divides two orthogonal polarization signals into one or two output fibers. The most common applications
are in polarization mode dispersion compensator, EDFA, Raman Amplifier, coherent telecommunication systems and
fiber optic sensor. It is characterized with high extinction ratio, low insertion loss and high directivity.
Above specifications are for device without connector.
*For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, and ER will be 2dB lower.
