FOCONEC supplies the CWDM mux demux module in single-mode fiber, with SC/APC, SC/UPC, LC/APC, LC/UPC connectors terminated.
It is ABS box packed, has 2 to max 18 channels with wavelengths between 1270nm and 1610nm, and each channel carries data independently from each other.
By deploying multiple channels/wavelengths, a coarse wavelength division multiplexing –CWDM provides flexibility to increase the capacity of existing fiber, and create more connection over a single fiber, allowing network designers to transport different data rates.
All CWDM mux/demux modules are protocol transparent and suit applications including 10/1G Ethernet, SDH/SONET, 8/4/2/1G Fibre Channel, FTTx, CATV, and widely used as a wavelength multiplexing technology for city and access networks.

Dual Fiber 4 / 8 / 16 Channel CWDM Port Configuration
FOCONEC’s CWDM products include:
- Stainless steel tube type CWDM
- ABS box type CWDM Mux/Demux modules up to 18 channels
- Cassette type CWDM Mux/Demux modules
- 19” 1U rack mount CWDM modules
Due to the low insertion loss is needed in WDM networks, we can also add “Skip Component” in a CWDM Mux/Demux module to reduce the IL as an option.
