CWDM Mux Demux

CWDM Mux Demux are used to combine two or more wavelengths onto a single fiber, and/or separate two or more wavelengths out of a single fiber. It is widely used in MAN (metropolitan area network), LAN (local area network) and PON (passive optical network).

CWDMs are able to transport up to 18 CWDM wavelengths with a channel spacing of 20 nm in the spectrum grid from 1271 nm to 1611 nm. (For the ITU CWDM wavelength grid, please refer to ITU-T G.694.2)


Based on thin film filter technology and epoxy-free in optical path

 Passive CWDM module, no power & no cooling required

 Cost-effective way to increase capacity of existing fiber infrastructure

 Up to 18 Channels between 1270 nm to 1610nm

 Various connectors and adapters are available - LC/APC, LC/UPC, SC/APC, SC/UPC, FC/APC, FC/UPC, etc.

 Various package type: steel tube, ABS box, cassette box, metal module, LGX, 19" 1U rack

 Monitor port, upgrade (expansion) port and other specified ports are available upon request



 Provide customized services, including but not limited to the operating wavelengths, port configuration, isolation desired, bandpass characteristics, package type and add skip component

 Transport protocol and rate transparent: different rates of data could be transmitted simultaneously across the same fiber link without disturbing other transmissions
