Kramer Electronics is pleased to announce the introduction of the 673T transmitter and 673R receiver for transmitting four channels of 3G HD-SDI, HD-SDI or SDI serial digital signals over fiber optic cable. The two units are the latest additions to the company’s TOOLS line of compact, high-performance signal management solution products.
The 673T and 673R are ideal for delivering long-range serial digital signal to live events, studio broadcasts, video production facilities, and any other application that requires the transmission of serial digital signals at ranges of up to 2950 feet (900 meters). The 673T converts up to four channels of incoming serial digital signals on BNC connectors to light pulses that are transmitted over a single fiber optic cable. The 673R converts the pulses back into four serial digital signals.
The 673T and 673R feature HDTV compatibility and a maximum data rate of up to 3.5Gbps for each input to support SMPTE 259M (SDI), 292M (HD-SDI), 424M (3G HD-SDI) and 372M (dual-link HD-SDI) signal data rates of 270Mbps, 1483.5Mbps, 1485Mbps and 2970Mbps. The fiber optic connection is over single multimode OM3 fiber optic cable with ST connectors and the units provide cable equalization up to 350m for SDI signals, 140m for 1.5GHz HD-SDI signals, and 120m for 3GHz HD-SDI signals.
