An optical supervisory channel (OSC) communicates inband with the remote IPLC
modules, as well as the optical ILA and is used for the analysis of the fiber span
characteristics, performance monitoring, and IPLC fault handing.
An optical splitter is used to broadcast the received signal from the output of the
preamplifier (E2) toward both
Four power monitors:
AWG Add—Monitors the input of the WSS measuring the total input power of the
combined channels of the local add function
Express In—Monitors the input of the WSS measuring the total input power at the
input to the WSS coming from the
Line IN—Monitors the input at the
signal optical power
Line OUT—Monitors the output at the
line signal optical power
OSC ADD—Monitors OSC power at
OSC DROP—Monitors OSC power at

IPLC Expansion Module Functional Components

The IPLC expansion module is a passive multiplexer/demultiplexer that interfaces only
with the IPLC base module. The IPLC expansion module receives its sole input from and
delivers its sole output to the IPLC base module through the
As such, it does not interface directly with the network or the high-speed backplane of
the PTX3000 Series router.
the IPLC base module and expansion module, which include:
Add filter capable of multiplexing 32 DWDM channels of certain wavelengths
Drop filter capable of demultiplexing 32 DWDM channels having the same certain
wavelengths
Demultiplexing filter whose input (which is also the sole input to the expansion module)
is monitored through a power detector. The power detector determines whether light
is present. If light is present, the power detector determines whether the light has
reached the expansion module through the patch cord between the IPLC base module
and the IPLC expansion module.
