# Product Documentation
4 Channels Double Fiber Passive DWDM Line Termination Unit DDLT-4
# Product Description

4 Channels Double Fiber Passive DWDM Line Termination Unit – DDLT-4 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.
DDLT-4 is passive double fiber 1-side Optical Add-Drop Multiplexer (OADM) package based on Thin-Film Filter (TFF) technology, allowing extract 4 data streams from ITU-T G.694.1 compatible Dense Wavelength Division Multiplex (DWDM). DDLT-4 acts as one side termination unit, meaning that link with is extracted in site where DDLT-4 is installed, is not added towards other side of DWDM link. DDLT-4 is manufactured as LGX type B module, installed in 19” 1U sub rack fitting any standard equipment rack.
