Single/Dual 12G/3G/HD/SD-SDI Distribution Amplifier (DA) with Optional Fiber Connectivity


The Densité HDA-3961 provides single and dual channel distribution for 12G/3G/HD/SD-SDI signals with flexible routing of inputs to outputs. Flexible output selection enables the HDA-3961 to be used either as a single channel DA with up to 10 outputs, or in dual channel mode with up to five outputs per input. The HDA-3961 provides up to ten reclocked outputs with automatic equalization for up to 60 meters (197 feet) of cable using Belden 4794R at 12 Gb/s, and 100m (328 feet) at 3 Gb/s and up to 150 meters (492 feet) at 1.5 Gb/s using Belden 1694A cable.
