Product Details
4 Channel CWDM Band Splitter / Combiner
GEZHI Coarse Wave Division Multiplexing (CWDM) modules combine or
split 4 wavelengths 1270nm, 1290nm, 1310nm, 1330nm into a single
fiber. Its consist by a Mux+Demux into a LGX cassette with a
epxress port for fiber extend and future development. Our 4 Channel
CWDM Band Splitter features wide channel bandwidth (15nm) in ITU
channel allocation.GEZHI CWDM Bank combiner isolation is greater
than 30dB for adjecent channels, and greater than 40dB for
non-adjacent channels. They have also high thermal stability.
