4 Wire Data
with Contact Closure
Fiber Link Card System
SYSTEM INSTALLATION INFORMATION
Description
The 4 Wire Data with Contact Closure Fiber Link Card system
provides simultaneous transmission of 4 wire data and
bidirectional contact closure over two optical fibers. It
supports full duplex constant transmission up to 9600bps
(9.6Kbps) in voice frequency range (300Hz-3.4KHz).
The card also interfaces with a dry contact and provides a
contact closure on the far end. The system includes
convenient contact closure input and output status LED
indicators.
The CO (Central Office) Side Card provides the electrical-
optical interface between a Central Office or PBX 4 wire
copper line and two fiber strands, and the Sub (Subscriber)
Side Card provides the optical-electrical interface between the
fiber and a 4-wire copper line to a RTU, PBX, modem or other
customer supplied equipment.
This industrial hardened Fiber Link Card system may be
installed into any RLH card housings, and is covered by our
Limited Lifetime Warranty.
Powering
The 4 Wire Data with Contact Closure CO and Sub cards may
be powered by local or line power. Cards can accept local
power from 22-56VDC@18 mA maximum, or power supplied
from the serving office @15mA.
Note: To maintain high voltage isolation, Fiber Link CO and
Sub cards must be powered from separate power sources.
