10/100 Ethernet
Fiber Link Card System
Environmentally hardened, substation grade
Description
The RLH 10/100 Ethernet Fiber Link Card system converts a
copper 10Base-T or 100Base-TX to a fiber optic 100Base-FX
transmission signal of either multimode or single-mode. The
cards transmit the data signals over fiber optic cable, allow for
network extension over long distances, and provide electrical
isolation between both ends of the network.
The Ethernet Fiber Link Card may be used as a complete
system, with a card at each end, or it may be connected
directly to any 100Base-FX device. The card includes Link
Fault Passthrough (LFP) mode with an LED indicator for link
loss failure that allows for rapid fault isolation.
This hardened, substation grade system is covered by our
Exclusive Unconditional Lifetime Warranty.
Note: The cards listed in this document replace all other
models. See the ordering section for part number information.

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.
• Use caution when handling copper wiring and follow appropriate safety regulations.
Special handling requirements
Be careful when handling electronic components
ATTENTION
ELECTROSTATIC
SENSITIVE
DEVICES
• This product contains static sensitive components.
• Handle Fiber Link 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.
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

Applications
Network equipment in high voltage areas can be at risk due to Ground Potential Rise (GPR). A copper
network cable referenced to a remote ground can become a path for high voltages during a ground fault.
Placement of all-dielectric fiber optic cable (instead of copper) completely eliminates the presence of a
remote ground, which dramatically increases safety of personnel and reliability of equipment. By utilizing
fiber optic cable, the Ethernet FIber Link Card provides absolute electrical isolation between both ends of
the network.
Copper twisted pair Ethernet is limited to 100m/328ft without extenders. Fiber optic cable provides long
distance service (up to 120km/74mi.) without any additional equipment. Fiber is immune to EMI/RF
interference, ground loops, and high voltage surges from lightning or ground faults, and is ideal in
electrically noisy environments such as near large power sources, electrical motors, and radio
communications equipment.

Installation
Prior to installation:
• Check for shipping damage
• Check the contents to ensure correct model and fiber type
• Have a clean, dry installation environment ready
Required for installation:
•24-56VDC (3W minimum) power source
•RLH Fiber Link Card housing
Measure the DC voltage of the source power to ensure that it is 24-56VDC (3W minimum). All electrical
and fiber optic connection are made directly onto the card. The Ethernet fiber link card is designed to be
installed into any RLH card housing.
Connect fiber optic cable
Multimode and single-mode Ethernet cards are equipped with either two ST or SC female optical
connectors, or a single SC bi-directional connector. Connect fiber cable to the Transmit (TX) and Receive
(RX) optical connectors. The other end of the fiber may be connected to another Ethernet fiber link card
or any 100BASE-FX Ethernet device.
The TX connector of each card must be connected the RX connector at the other end. For bi-directional,
single fiber models, there is only a single SC connector used for both transmitting and receiving. Always
route fiber optic cable loosely avoiding tight bends.
Connect Ethernet cable
The TP (RJ-45) Ethernet port will auto-sense for 10Base-T or 100Base-TX connections.
The port is auto MDI/MDIX, which means that the card can connect to another card, switch or
workstation without changing straight through or crossover cabling.
Page 4!!!RLH Industries, Inc. • Tel. 866-DO-FIBER • Fax [phone] • www.fiberopticlink.com

Connect Power
Connect a 24-56VDC (200mA minimum) power source to the screw-down terminal on the Ethernet card.
The power input is not polarity sensitive. The terminal unplugs from the card to make wiring easier.
DIP Switch Settings
The front panel DIP switches may be set for optional modes. The factory default is ON for all switches.

Recycle power (See note)
After changing any of the DIP switches, recycle the power to the card by flipping switch 6 (Reset) from ON to RST then
back to ON.
DIP switch 2 must be set to MAN when switches 3 and 4 are set to 10 and HDX respectively.
Note: Connecting an auto-negotiating device to a non-auto-negotiating device may result in an
unpredictable port setting with poor link performance. When operating in Manual mode, both mating ports
must be set to the same data rate and duplex mode.

Troubleshooting
If trouble is encountered, verify all copper and fiber connections and settings. If any of the DIP switches
were changed, you must recycle the power by flipping switch 6 to RST (Reset) and ON again to enable
the settings. Refer to the LED Indicators on the front panel, they show availability of power, modes of
operation, and data being received by the fiber and TP port.
