The ILC156 is a 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 ILC156 is a cost-effective and power-efficient 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 ILC156 supports links in excess of 80 km using hot-swappable 10G XFP transceivers in WDM, CWDM, and DWDM wavelengths. Installing a ILC156 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 ILC156 can also be used as a transport aggregator for Artel’s ILC274 four-channel TDM module.

With its format flexibility, easy configuration, and competitive price, the ILC156 is an ideal solution for fiber constrained, multi-service video transport applications.
