Video and data hub converts coaxial television signals into balanced signals transmitted on pair four of Cat 5/6 cable. Ethernet or phone signals enter the back of the hub via RJ-45 ports and pass through to the cable on pairs one, two or three. At the point of use Lynx converter changes the television signals back to coaxial signals accessible via an F connector. The Ethernet (or phone) signal is accessible via an RJ-45 jack. No external power is required. The passive design permits bi-directional operation and is extremely reliable.
