Kramer AV 673R/T
4-Channel 3G HD-SDI over Optic Transmitter & Receiver Set
The 673R/T from Kramer is a high-performance fiber optic 4-channel transmitter/receiver pair (673R & 673T) for video signals up to 3G HD-SDI and dual link HD-SDI signals. This pair works by having the transmitter (673T) convert up to four channels of SDI signals on BNC connectors to an optical signal that is transmitter over a single fiber optic cable. The receiver (673R) the takes in the optical signal and converts it back to SDI signals for use on a HD display. The 673R/T is great for long range multimedia distribution type settings with a maximum system range of 3200', for example, cinemas, stores, entertainment centers, professional home theater setups, and also video production and broadcast facilities.
The 673R/T is HDTV compatible and has a multi-standard operation meaning it can send and receive SDI, HD-SDI, 3G HD-SDI and dual link HD-SDI signals. The cable type this system uses is high-quality fiber cable - a single multi-mode OM3 fiber optic cable with SC connectors. There is also reclocking and equalization per each of the four channels allowing for signal strength and quality to be made over extended distances. The front panel contains LED indicators to represent Fiber Optic, Source, and Input Selection.
The 673R/T come in a compact and rugged DigiTOOLS sized enclosure allowing for 3 devices to be rack mounted side by side in a 1U rack space using the optional Kramer RK-3T rack adapter. A power supply and bracket installation kit are included with the pair, and they are backed by a 7 year warranty from Kramer.
