The Kramer 673R/T 4-Channel 3G HD-SDI over Single Fiber Optic Transmitter & Receiver is ideal for converting 3G HD-SDI and dual link HD-SDI signals to optical signals and vice versa. The transmitter converts up to 4 channels of SDI signals to optical signals, while the receiver converts them back to SDI signals.
Featuring reclocking and equalization for each channel, the system offers error-free transfer of signals for up to a distance of 3200’ (1000 m) via a single multimode OM3 fiber optic cable with SC connectors. It also includes LED indicators to indicate detection of fiber optic, source, and input signals.
The 673R/T system is compatible with HDTV signals and offers different operation standards such as SDI (SMPTE 259M), HD−SDI (SMPTE 292M) and 3G HD−SDI (SMPTE 424M), and dual−link HD−SDI (SMPTE 372M).
