CAUTION ! AVOID DIRECT EXPOSURE TO BEAM.
All –5, -7, -8, and -9 Models use laser diodes. These solid-state
laser diodes are located in the optical ports of these units. Laser
diodes produce invisible radiation that may be harmful to human
eyes. Never look directly into the optical port of any fiber optic
unit designed to operate with single-mode optical fiber.

Initial Setup and Alignment Instructions
After the initial installation the units must be adjusted to compensate
for the unique losses in your fiber optic cables. This is a one-time
Office
adjustment. There are two different procedures depending on your
installation. (For PBX to PBX links, please see application note for a
special calibration procedure.)
Telephone to Telephone Line
1. Connect the TLPX-1001 and TLLX-1001 to each other with two
fiber optic cables. Be certain the Tx optical ports of each unit are
connected to the Rx optical ports of the companion unit. Connect
the telephone set, but do not connect the telephone line.
2. Apply power to both units. Turn the Gain adjustment on both units
fully counter clockwise.
3. Slowly adjust the Gain control on the TLPX-1001 until the
telephone rings. Turn the Gain control counter clock wise 1/8 of
turn beyond the point where the phone stops ringing.
4. Place in the “off-hook” mode. If the Sig indicator on the TLLX-
1001 is not already lit, slowly adjust the Gain control on the TLLX1001 until the Sig indicator just illuminates. Do not adjust the
control further.
5. Place the telephone set in the “on-hook” mode. Connect the
telephone line. The system is now ready for operation.
Telephone to Telephone for an intercom use.
Using two TLPX-1001 units and two standard telephone sets as an
intercom.
1. Connect both TLPX-1001 units together with fiber optic cable and
connect a standard telephone to both TLPX-1001 units. For
reference purposes call one side of the link “A” and the other “B”.
2. Lift the telephone set connected to “A” and slowly turn the Level
control on the TLPX-1001 at “B” (with the telephone at this
location on hook) clockwise until the phone just rings. Do not turn
further.
3. Replace the telephone at “A” and determine that the telephone at
“B” stops ringing.
4. Lift the telephone set connected to “B” and slowly turn the Level
control on the TLPX-1001 at “A” (with the telephone at this
location on hook) clockwise until the phone just rings. Do not turn
further.
5. Replace the telephone at “B” and determine that the telephone at
“A” stops ringing.
