Interlogix S7717DT-RST1 Specsheet

Singlemode

Singlemode Fiber Transmission System

Bi-directional digital current loop data transmission

The S7717D digital current loop transmission system provides
superior noise-free transmission of the 20 mA standard suitable for
use in many applications including those found in communications
and monitoring systems. A complete system consists of a transmitter
and a receiver operating over one or two single-mode fibers. Utilizing
high-speed data conversion and digital transmission, the system
provides highly accurate data transmission. The units can be
configured as active or passive receivers and drivers. The
SMARTS diagnostic technology provides an built-in diagnostic
LEDs for monitoring data and optical signal strength.
