Description of 3CH CWDM
3CH CWDM Mux Module ABS Box with customized wavelength and
connector
CWDM
CWDM DEMUX Module ABS box 1470-1610nm with SC/APC Connector is
based on dielectric thin-film technology designed for integration
in low cost Metro and Access networks. These include applications
such as fiber to the home, business or curb. The module enables 4
or 8 or 16 channels to be either combined or separated.CWDM module
has low insertion loss, high channel isolation, and flat passband.
Additional filters, to enable cascading of devices, or addition of
1310nm or other wavelength, can also be included in the module.

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.
