The 54 to 860 MHz Z-Distribution FBR, RF video hub (not a switch), distributes 134 NTSC/6 MHz channels or hundreds of HD/SD channels over a structured, “568” Category cable system. The video hub automatically splits, amplifies, slopes, and adjusts input and output signals to maintain level integrity. The back-bone cable can either single-mode fiber (angle polished) and/or standard coax cascaded to other hubs in a star topology. Hubs are bi-directional, and are capable of remote broadcasts, and handling return channel information, video-on-demand, using DOCSIS or FSK.
The active hub can auto-adjust input signals ±3dB in both slope and level to minimize signal variations from the service provider.
