2.0mm SC/APC ABS BOX 8CH Optical CWDM Multiplexer ModuleProduct Description:Coarse Wavelength Division Multiplexing (CWDM) networks need multiplexer/demultiplexer (MUX/DEMUX) modules to combine and split the multi-wavelength optical signals. These modules are generally called
CWDM MUX/DEMUX. Coupled with highly reliable passive optics (e.g., CWDM SFP/SFP+), CWDM MUX/DEMUX modlues let operators make full use of available fiber bandwidth in local loop and enterprise architectures.
Lightwit Photonics provides a series of CWDM MUX/DEMUX modules with as more as 18 channels (20nm spaced) in simplex or duplex configurations. All the CWDM modules are available with three types of packaging: ABS Pigtailed Box, Rack Chassis and LGX Cassette.
