Description of 4CH CWDM
4CH Fiber CWDM Cassette Module with LC UPC Adaptor
CWDM
CWDM MUX DEMUX Module is compact coarse wavelength division
multiplexer, It provides channels up to 16 even 18 with 20nm channel spacing from
1260~1610.CWDM MUX DEMXU Modules based on optic bench platform(that
consists of multiple filter collimator and substrate,wedges) to
greatlyy reduce manfuacturing cost and improve optical
performance.For compact CWDM MUX DEMUX applications.

Optical Path
Single Fiber Bidirectional Transmission The wavelength of TX and RX is Different |
Dual Fiber Bidirectional Transmission The wavelength of TX and RX can be Same or Different |
CWDM systems can transport 18 wavelengths (1270~1610nm) with a
channel spacing of 20nm. In custom application typically use 1470
to 1610nm in the spectrum grid. Compare with DWDM, CWDM has a wider
channel spacing than DWDM.
