The F-HDMI-SMSC transmitter and receiver pair are used to carry HDMI video signals over longer distances than have traditionally been available. Thor singlemode HDMI over fiber systems only need a single strand of singlemode fiber optic cable with SC connectors. Modern SM-FOC gives these units a range of up to 25km. HDMI video cables are expensive and have a very limited range, typically less than 50 ft. Longer runs of HDMI cables also experience significant distortion of the signal. The F-HDMI-SMSC system allows a user to transport full uncompressed HDMI video at 1080i/1080p with up to 8 incorporated audio signals over a simple and inexpensive fiber optic cable. A simple passive DVI to HDMI adapter can also be used to transport DVI signals over the fiber. For extending set top boxes we also have a IR return path option. This uses an IR receiver at the receiving end to transmit commands from an IR remote over a return optical path. The IR signals are then rebroadcast via an included LED to control equipment on the transmitting end.
