About the Fiber Module
Use this module when a medium-distance (distances of 3000m/ 9843ft) fiber link is
required between two ControlNet products. This fiber link provides ground
isolation between nodes and is less susceptible to noisy environments than
traditional copper media.
IMPORTANT
The distance that can be supported is dependent on the quality
of the fiber, number of splices, and connectors. The total loss of
the fiber link must be less than 13.3 dB.
The module provides:
• two fiber channels
• activity LED indicators for each fiber channel

3. Press the module down onto the DIN rail until flush.
The locking tab should snap into position and lock
the module to the DIN rail.
4. If the module does not snap into position, use a screwdriver or similar
device to move the locking tab down while pressing the module flush onto
the DIN rail. Release the locking tab to lock the module in place. If
necessary, push up on the locking tab to lock.

5. Remove the protective backplane cap as shown in “Remove the Protective
Caps” on page 8.
6. Once attached to the DIN rail, slide modules to the left to mate with the
repeater adapter or another repeater module.

Be certain that the adapter and repeater modules are secured
together with DIN rail anchors. Failure to do so may result in
the loss of communications and/ or cause damage to the
modules. The total number of modules that can be attached to
the repeater adapter can not exceed four or the total power
consumption of the modules can not exceed 1.6A @ 5VDC,
whichever comes first.

7. Connect the fiber cable as shown in “Connect the Fiber Cable” on page 11.
If you exceed the module or power limit, you may cause damage
to the repeater adapter and modules.
If this is the right–most module, a DIN rail latch must be used on
the right side of the fiber module.

IMPORTANT
Choose Fiber Cable Types
Multi-fiber cables for backbone use are available with a wide range of fiber counts;
between 2 and 216 fibers. The following figure shows an example of a multi-fiber
backbone cable and two fiber interconnect cable.
The type of fiber cable you choose to use depends on the network environment.
Consult your installation professional to determine
the best type of cable to use for your environmental
conditions.

Estimate Cable Lengths
The maximum length of a fiber cable section for the
9904-RPFM is dependent on the quality of the fiber,
number of splices, and the number of connectors.
The total attenuation for a cable section must be
less than 13.3dB.
Typically cable attenuation for a wavelength of 1300nm is less than 1.5dB/km.
zipcord
Each fiber system has different constraints, therefore determining maximum fiber
optic cable lengths differs for each system. The 9904-RPFM is designed to solve
medium distance applications that require 3km (9843ft) between two ControlNet
products. We guarantee up to 3km, but you can achieve greater distances by
increasing the quality of the fiber cable and termination connector media. The
medium distance module provides ground isolation between nodes and is not
disrupted by the noise that affects traditional copper media.
Avoid splicing your cable. Connectors can cause considerable
attenuation and limit the maximum length of your system. Be
certain to check the attenuation of different cable sections
after the cable is installed.

Specifications for 9904-RPFM Fiber Optic Cable
The quality of the fiber cable determines the distance you can achieve. Consult
your local distributor for attenuation specifications prior to purchasing your fiber
media components. The table below provides specifications for fiber optic cable:
Item Description
Fiber Type 62.5/125 micron
Fiber Termination Type
Fiber Operating Wavelength 1300 nm
Optical Power Budget

This includes all loss associated with the fiber link, including: splices, fiber attenuation, bulkhead
connectors, and the 9904–RPFM ST terminations.
The medium-distance fiber module (9904-RPFM) is designed for use with 62.5/
125µm multi-mode optic fiber and plastic or ceramic ST type connectors. The
wavelength used is 1300 nm.
Termination is simply the process of attaching a connector to the ends of our fiber
cable. We recommend that you use a quality kit such as the Corning Cable Systems
Termination Kit with the unicam ST connectors. The Corning Cable Systems
Termination Kit has proven to be a simple and reliable method to terminate fiber
cable.

Connect the Fiber Cable
If you are going to use only one channel, use either Channel 1 or Channel 2.
To connect the cable for Channel 1:
1. Connect to Channel 1 Receive (RX).
a. Align the knob of the cable connector with the groove of the module
connector, and insert the connector into Channel 1 RX.

Be certain that the fiber cable you connect to Channel 1 (RX)
on one 9904-RPFM repeater to Channel 1 (TX) on the other
9904-RPFM repeater. You can use Channel 1 or Channel 2 on
either module.
The total number of fiber repeaters (9904-RPFS, RPFM)
between any two nodes (path) is limited to 5 repeaters and 6
segments. You may have many repeaters in a system, but a
maximum of five repeaters between any two nodes.
