# Product Documentation
# Product Description

    8 Channels Single Fiber Passive CWDM Mux/Demux – SCMD-8B is member of EDGE Optics xWDM Series product line. We designed EDGE Optics xWDM Series products to allow easy, gradual, logical and cost efficient expansion of network bandwidth using industry leading passive WDM technology. Main advantage of xWDM is its passive nature – no power supply or cooling necessary, robustness – no special micro-climate requirements and as passive element, it has MTBF 100+ Years. xWDM is – it is fully data rate or line protocol neutral – it is possible to use with colored transceivers supporting such applications as 1G/10G Ethernet, SDH/SONET and 8/4/2/1G Fiber Channel. It’s simple to install, requires no configuration or maintenance.

SCMD-8B is passive multiplexer/De-multiplexer package based on Thin-Film Filter (TFF) technology, allowing organize 8 duplex and parallel protocol independent ITU-T G.694.2 compatible Coarse Wavelength Division Multiplex (CWDM) data streams over single fiber of single mode optical fiber. With our focus to provide maximally low insertion loss, SCMD-8B is equipped with band-pass or skip filters extending maximum distance of CWDM connections. SCMD-8B is manufactured as LGX type B module, installed in 19” 1U subrack fitting any standard equipment rack. SCMD-8B is used togeather with counterpart SCMD-8A module in other end of line. Monitor port(1%) ensures easy troubleshooting without downtime.
