Many times in facility-wide installations or infra-structure digital video signals are extended from central equipment location like rack or server room to displays or consoles located more than 500-ft (150-m) to 16,000 (5 km). Use of copper via HDMI or DVI direct cables or via UTP cable gives limited distance so use of fiber cables is preferred. The typical installation are for medical facilities like hospital, corporate IT infrastructure, digital signage, kiosks, public displays, institutional, government or campus-wide installations.

Teq AV/IT has taken a lead as world's best HDMI and DVI extender manufacturer over world with its new innovative and broad fiber extender product line.

With lower cost of fiber cables and connectors or already existence of these cables for data network infra-structure, it has become more affordable to implement HDMI/DVI extender over fiber cables. Extending digital video signals DVI and HDMI over fiber offers two distinctive advantages over its copper or UTP cable predecessors: Loss-less digital HD quality of video signal and longer (minimum double to 30-fold longer extending distance). For extending Digital signage players, kiosks, public displays, presentation projectors or KVM consoles or computer, there is no better extending medium than fiber.
