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:
