# Product Documentation
# Product Description

40 Odd Channels Double Fiber Passive 50 GHz DWDM Mux/Demux – DDMD-40-50 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.
DDMD-40-50 is passive multiplexer/demultiplexer package based on AAWG (Athermal Arrayed Waveguide Grating) technology, allowing to organize 40 duplex, protocol independent parallel ITU-T G.694.1 compatible Dense Wavelength Division Multiplex (DWDM) data streams over pair of single mode optical fiber. DDMD-40-50 supports 40 50GHz Odd channels and it can be used as standalone, or togetaher with DDMD-40-50I by plugging it to Upgrade port. DDMD-40-50 is manufactured as standart 1U high 19” subrack fitting any standard equipment rack.
