4 Channels Double Fiber Expandable Passive CWDM Mux/Demux Description
4 Channels Double Fiber Expandable Passive CWDM mux/demux – DCMD-4HE is a member of the 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. The main advantage of xWDM is its passive nature – no power supply or cooling necessary, robustness with no special micro-climate requirements, and as a passive element, it has an MTBF of 100+ years. xWDM is fully data rate and line protocol neutral – it is possible to use with colored transceivers supporting applications such as 1G/10G Ethernet, SDH/SONET, and 8/4/2/1G Fiber Channel. It is simple to install and requires no configuration or maintenance. DCMD-4HE is a passive multiplexer/demultiplexer package based on Thin-Film Filter (TFF) technology, designed to organize 4 duplex, protocol-independent ITU-T G.694.2 compatible Coarse Wavelength Division Multiplex (CWDM) data streams over a pair of single-mode optical fiber. DCMD-4HE operates within the CWDM High-Band range of 1510-1570nm and supports extension via an upgrade port, which can be used to connect legacy gray wavelengths in the range of 1260-1460nm or expand with low-band CWDM multiplexors, such as DCMD-8L or DCMD-4L. The unit features LC/UPC connectors. With a focus on minimal insertion loss, DCMD-4HE is equipped with band-pass or skip filters extending the maximum distance of CWDM connections. DCMD-4HE is manufactured as an LGX-type package, installed in a 19" 1U sub-rack fitting any standard equipment rack. The 1% monitor port ensures easy troubleshooting without downtime.
