3 Overview
The 673T is a high-performance fiber optic transmitter for 3G HD-SDI,
HD-SDI, SDI, and dual-link SDI signals. The unit converts up to four
channels of serial digital signals on gold-plated BNC connectors to light
pulses that are transmitted over a single multimode fiber optic cable to a 673R
receiver that converts them back to serial digital signals.
The 673T and 673R pair has a transmission range of 1000 meters (more than
3,200ft).
Both the 673T and 673R:
•Feature a maximum data rate of up to 3Gbps, enabling it to be used for
standard definition, high definition and the new 3G high definition serial
digital video signals (SD/HD-SDI)
•Feature a single multimode OM3 fiber optic with SCconnectors
•Include four HD-SDI signals on gold-plated BNC connectors each for the
transmitter and the receiver
