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