Description
The DLC156 is an innovative, six channel TDM multiplexer for transporting uncompressed and compressed video over dark fiber or managed optical networks such as ROADM and OTN. Users can mix and match SD-SDI, ASI, HD-SDI, or 3G-SDI services into a single 10.7 Gb/s optical transport stream.
The DLC156 TDM Multiplexer for the DigiLink chassis is a space efficient, cost-effective module for transporting up to six HD-SDI or three 3G-SDI digital video services over a single optical wavelength, saving fiber cost and simplifying network design and deployment. Using time division multiplexing (TDM), each channel is assigned a fixed time-slot, eliminating complex configurations. Six independent, mixed format video signals are aggregated to a single wavelength and two time slots can be combined to carry 3G-SDI.
The DLC156 supports links in excess of 80 km using industry standard, hot swappable 10G XFP transceivers in WDM, CWDM, and DWDM wavelengths. Installing a DLC156 repeater between the link source and destination extends the range of a link. Up to 240 uncompressed HD channels are possible over a single fiber.
For additional flexibility, the DLC156 can also be used as a transport aggregator for Artel’s DLC274 four-channel TDM module supporting as many as 960 270 Mb/s video services over a single fiber. With its format flexibility, easy configuration via on-board switches or DL-Manager, and competitive price, the DLC156 is an ideal solution for fiber constrained, multi-service video transport applications.
