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)
