DESCRIPTION
The RFL Fiber Service Unit (FSU) provides an interface between synchronous electrical signals and
optical fiber. It can be used with the RFL 9300, RFL 9745, RFL IMUX 2000 or other types of
multiplexers. It can also be used with any other C37.94 compliant, end device. There are a total of five
varieties of FSUs using both single and multimode fiber heads. They use RS-449, V.35, G.703, X.21
and E1 as inputs and outputs on the non-fiber side of the connection. Note that there is a modification
allowing the unit to be mounted into a 1U Chassis. The FSU is a stand-alone device, which is
essentially a translator to and from data sent using these five interface standards in accordance with the
IEEE C37.94 fiber protocol. The G.703 is 64,000 bps only and thus it has N fixed at 1. The other four
versions use a DIP switch to set the value of N. The characteristics of each of the five types of Fiber
Service Units, is shown in Tables 1, 2 and 3. Mounting dimensions are shown in Figure 12, except for
the 1U version of the unit which is shown in Figure 6 and 9.

INSTALLATION
Installation involves mounting the FSU module in its desired location, connecting all signal, coaxial and
power cables, and programming the module data rate and other configuration settings.
Note 1: Instructions for the 107460-1 thru -4 FSU units also apply to the following units.
108015-1 thru -4, 107460-1-1, 107460-1-2, 107460-2-2 and 107460-3-1
Note 2: Instructions for the 107460-5 FSU also apply to the 108015-5 and 107460-5-1 units.
To install the module, proceed as follows:
1. Carefully inspect the module for any signs of shipping damage. If you suspect damage to the
m
odule, immediately call RFL Customer Service at the number given at the bottom
of this page.
2. Check the assembly number on the front panel of the module to make sure the unit is compatible
with y
our interface requireme
nt as shown in Table 1.
3. Use Table 7 as a wiring guide for the D subminiature connector if your interface is RS-449 or
V.35. Use Table 8 as a wiring guide for the D subm
iniature connector if y
our interface is X.21 or
G.703. Use Table 9 as a wiring guide for the D subm
iniature connector if your interface is 120 ohm
E1. Use Table 10 as a wiring guide for the BNC connectors if your interface is 75 ohm
E1. When
fastening the D subm
iniature connector, make sure that the screws on both ends of the ma
ting
connector are tightened to secure the connector to the FSU front panel.
NOTE
ALL CABLING TO AND FROM THE FIBER SERVICE UNIT INTERFACE CONNECTOR
MUST UTILIZE SHIELDED TWISTED PAIR OR COAXIAL CABLE TO MINIMIZE
CROSSTALK AND INTERFERENCE FROM EXTERNAL SOURCES.
CAUTION
BEFORE ATTEMPTING TO MAKE POWER CONNECTIONS TO THE FIBER SERVICE
UNIT, MAKE SURE THAT YOUR POWER SOURCE IS COMPATIBLE WITH THE FSU. IF
THE IMPROPER VOLTAGE IS CONNECTED TO THE FSU, COMPONENT DAMAGE MAY
RESULT.
A suitably rated power disconnect device and over current protection device (e.g. fuse or circuit
breaker) must be installed between the station battery supply and the FSU power input. The
over current protective device should be rated at 0.5 to 1.5 Amps.
4. Connect input power to the following terminals on the rear-panel terminal block connector TB1, as
shown in Figure 5, see Figure 6 and 9 for 1U chassis installation.
Station battery positive TB1-1
Station battery negative TB1-2
Ground TB1-3
5. Fiber optic cables with type ST series bayonet fiber optic connectors must be connected to the fiber
optic heads on the front panel of the FSU m
odule a
nd to the far end chassis. When connecting fiber
optic cables, m
ake sure the connectors are properly aligned before tightening, and then fully
tighten
them
. This will help minim
ize losses in the connector.

SW201 Selects impedance of E1 port as follows:
Set to 75 when using 75-ohm BNC ports
Set to 120 when using 120-ohm DB-15 port
SW203 Used to set E1 operating parameters as follows:
SW203-1 Selects Timing Mode
ON = Thru timing
OFF = Internal timing
SW203-2 For factory use only (Switch must be set to ON position)
SW203-3 Selects Normal operation or Transmit all ones, on E1 port.
ON = Normal operation (default setting)
OFF = Transmit all ones
SW203-4 Enables or disables jitter attenuator
ON = Disable jitter attenuator
OFF = Enable jitter attenuator (default setting)
SW203-5 Jitter attenuator selection
ON = Receiver (default setting)
OFF = Transmitter
SW203-6 Selects inverted data
ON = Inverted data
OFF = Normal operation (default setting)
