Connector Handling
1)
NEVER TOUCH THE FIBER END FACE OF THE CONNECTOR.
2) Connectors not in use should be covered over the ferrule by a plastic dust
cap. It is important to note that inside of the ferrule dust caps contains a sticky
gelatinous residue that is the by-product of the making of the dust cap. This
residue will remain on the ferrule end after the cap is removed. Therefore it is
critical that the ferrule end be cleaned thoroughly BEFORE it is mated to the
intended unit.

Troubleshooting
Common problems include lack of continuity in the optical fiber, lack of power (or
reversed power), or improper input levels. The units are designed to work with a
75 Ohm system. Consult IOM2806 for additional troubleshooting of the transmit-
ter. If problems persist, contact the factory.

Repair Service
For equipment repair or technical assistance, contact Customer Service (800) 732-
5252 (USA) or (540) 382-0462. A Returned Material Authorization (RMA) number
must be issued by Customer Service before the return of a failed unit. Units should
be returned in their original shipping carton, if available. Always include a com-
plete description of the failure or observed anomalies. All units are marked with
model number and serial number. This identification sticker is placed on the rear
panel (transmitter) or on the product label (receiver). The serial number is a date
code used as a reference for warranty service.
Problem
Check
Comments
No optical power out of Tx.
Check Tx AC power connec-
tion.
If AC power is connected,
check the primary AC power
source to verify it is working.
Contact Force, Inc. if no
cause for this problem can be
found.
No optical power at the 2809
Rx.
Check optical power output at
the Tx.
If there is optical power at the
Tx output, verify proper fiber
is connected to the Rx. If the
proper fiber is connected,
ensure the integrity of the
fiber.
Signal out of 2809 Rx is noisy.
Check optical power at the
Rx.
See IOM2806 for the correct
transmitter input levels
required for proper opera-
tion. Be sure to ground the
case of the Tx and Rx. Also,
verify that all optical connec-
tors are APC type.
No signal out of Rx.
Verify the input signal at the
Tx.
See IOM2806 for the correct
transmitter input levels
required for proper opera-
tion.
Signal out of Rx is distorted.
Verify input signal at Tx.
The Tx input must be within
the specs given in IOM2806.
A larger signal will cause dis-
tortion.
Verify fiber size.
Single-mode fiber must be
used with this product.
