If the output power is with acceptable limits, clean and reconnect the transponder and OT
or SVAC and check the alarm status of the shelf. If the output power remains below
specification:
1. Reseat the transponder card. Refer to “Reseating a Card” (p. 3-19).
2.
Measure the optical output power of the transponder. If the output power remains
below specification, Replace the card. Refer to “Replacing System Components”
(p.
3-20). Follow the return and repair process in the Customer and Product Support
guide
to return the faulty card to an authorized repair center for replacement.
3. If the source transponder for the signal is outside the 1830 PSS (alien channel
transport case) replace the source transponder.
4. If the source optical interface is a replaceable pluggable optical module, replace the
SFP or XFP module (see “Replacing an SFP Module” (p. 3-27) or “Replacing an XFP
Module”
(p. 3-30)).

If the encoder is an OT (VA, SVAC or MVAC) port, using an optical power meter,
measure the optical power being received.
If... Then...
the loss over the fiber between the transponder
and OT VA/SVAC/MVAC port is reasonable,
continue with Step 7.
the
loss over the fiber between the transponder
and OT VA/SVAC/MVAC port is higher than
expected,
clean, inspect and connect the fiber between
the transponder and OT VA/SVAC/MVAC
port.

6
Measure the optical power being received at the OT VA, SVAC or MVAC In port.
If... Then...
the loss over the fiber between the transponder
and OT VA/SVAC/MVAC port is reasonable,
clean and reconnect the transponder and OT
VA/SVAC/MVAC port and check the alarm
status of the shelf.
the loss over the fiber between the transponder
and OT VA/SVAC/MVAC port is higher than
expected,
replace the fiber.

7
Clean the OT VA, SVAC or MVAC In port. Clean and reconnect the fiber between the
transponder and OT VA, SVAC or MVAC port. Check the alarm status of the shelf.
