6 Channel TDM Multiplexer for 3G, HD, SDI, and ASI 

[DLC156] 

DigiLink Video Transport System 

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 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, and competitive price, the DLC156 is 

an ideal solution for fiber constrained, multi-service video transport applications.
