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.

General Safety Practices
The equipment discussed in this document may require tools designed for the purpose being described.
RLH recommends that service personnel be familiar with the correct handling and use of any installation
equipment used, and follow all safety precautions including the use of protective personal equipment as
required.
Caution - Severe Shock Hazard!
•Never install during a lightning storm or where unsafe high voltages are present.!
•Active phone lines may carry high DC voltages. Use caution when handling copper wiring.!
•Observe the power requirements of this device and use appropriate power sources.
Special Handling Requirements
Be careful when handling electronic components
"
•This product contains static sensitive components. !
•Handle the cards at their edges only.!
•Follow proper electrostatic discharge procedures.!
This card utilizes circuitry that can be damaged by static electricity. When transporting the card, carry it in
an ESD safe container such as the antistatic bag provided with the card. Before handling cards, discharge
yourself of static electricity by physical bodily contact with earth ground. When handling cards, hold by
outer edges and avoid touching circuitry. Failure to follow ESD precautions may cause serious damage to
the card and prevent proper operation.
Warning!
The intra-building port(s) of the equipment or subassembly is suitable for connection to intrabuilding or
unexposed wiring or cabling only. The intra-building port(s) of the equipment MUST NOT be metallically
connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as
intra-building interfaces only (Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation
from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to
connect these interfaces metallically to OSP wiring.

Guidelines for handling terminated fiber cable
"
•Do not bend fiber cable sharply. Use gradual and smooth bends to avoid damaging glass fiber.!
•Keep dust caps on fiber optic connectors at all times when disconnected.!
•Do not remove dust caps from unused fiber.!
•Keep fiber ends and fiber connectors clean and free from dust, dirt and debris. Contamination will cause
signal loss.!
•Do not touch fiber ends.!
•Store excess fiber on housing spools or fiber spools at site!
Installation

4-Wire Data with Contact Closure System Diagram
Before installing
• Check for shipping damage. In case of damage, file a claim immediately with the carrier, then contact RLH
customer service.
• Check the contents to ensure correct model, mode and fiber connector type.
• Have a clean, dry installation environment ready.
Required for installation
• RLH card housing for RLH Fiber Link Cards.
• 24-56VDC@18mA local power sources as needed.
The 4 Wire Data with Contact Closure Fiber Link Card is designed to be installed into any RLH card
housing. The housing should be properly installed before installing the card. All electrical and fiber optic
connection are made directly onto the card.

4 Wire Data with Contact Closure Card Connectors
Connect fiber optic cable
Fiber Link cards are equipped with two optical connectors. Connect fibers to the transmitter and receiver
marked TX and RX. Connect the transmitter (TX) fiber on one card to the receiver (RX) fiber on the other
card and vice versa. Always route fiber cable loosely, avoiding tight bends.
Connect 4 wire data pairs
The analog voice-frequency data transmission supports full duplex constant transmission up to 9600 bps.
The module has a contact output that corresponds to the contact input on the opposite end module.
The copper pairs from the CO or PBX connect to the green SEND/INPUT and RECEIVE/OUTPUT screw-
down terminals on the CO Card.
The copper pairs from the remote terminal connect to the green SEND/INPUT and RECEIVE/OUTPUT
screw-down terminals on the Sub Card.
Connect contact closure leads
Connect the contact closure leads to the black contact closure INPUT and green Contact Closure
OUTPUT screw terminals. The INPUT of one side corresponds to the OUTPUT at the other end. The
contact input is a dry contact only. Output is a normally open contact only.
"
Contact Closure Connection Diagram
Contact closure operation status may be determined from the 2 status LED’s. The red LED is ON when
the input is active, and OFF when no input is present. The yellow LED is ON when the contact closure
output is closed, and OFF when the output is open.

RJ-45 connectors
RJ45 adapters are available to enable connections to the cards using a standard RJ-45 connector. RJ
jacks are gel filled to prevent corrosion.
CO side RJ adapters connect pins 1,2 to the card input connector and pins 7,8 to the card output.
Sub side RJ adapters connect pins 7,8 to the card input and 1,2 to the card output. Refer to the Ordering
information for CO and SUB side RJ connector part numbers.

"
Connect Power
Connect a 24-56VDC (15mA minimum) local power source to the black AUX. P.S. screw-down terminals
on the Card. The power input is not polarity sensitive. The CO card can operate off of simplexed line
power on the SEND/INPUT and RECEIVE/OUTPUT pairs where available.
Troubleshooting
If trouble is encountered, verify all connections, signal and voltage levels. If trouble persists, replace the
unit and retest. If technical assistance is required, contact RLH Industries, Inc. Technical support
department. Refer to the contact information at the end of this document.
