Patch Panels
Introduction
This document explains how to install and operate the Cisco ONS 15216 100 GHz
40-channel mux/demux patch panel.
The Cisco ONS 15216 40-channel mux/demux patch panel is a new ONS 15216
FlexLayer unit that allows 40-channels of ITU wavelengths to be placed onto a
single fiber, and removes 40-channels of ITU wavelengths from a single fiber.
The ONS 15216 40-channel mux/demux patch panel can be odd or even patch
panels:
•15216-MD-40-ODD=: 40-channels spaced at 100 GHz on the Odd ITU grid
•15216-MD-40-EVEN=: 40-channels spaced at 100 GHz on the Even ITU
grid
The only difference between the 15216-MD-40-ODD and 15216-MD-40-EVEN
is the operating 100 GHz ITU grid. See “Channel Wavelength Allocation” section
on page 5 for C-band channel wavelength plan for the odd and even patch panels.

The patch panel can combine 40-channels of ITU wavelengths spaced at 100 GHz
to a denser DWDM signal and separate the combined signal to 40-channels of ITU
wavelengths spaced at 100 GHz. To increase the network capacity, the patch panel
is plugged with an interleaver and deinterleaver module and is used along with
another patch panel of a different grid. The interleaver module combines the
signals from the 15216-MD-40-ODD and 15216-MD-40-EVEN patch panels
spaced at 100 GHz to a denser DWDM signal spaced at 50 GHz and the
deinterleaver module splits the combined signal (80 channel signal) to the
15216-MD-40-ODD and 15216-MD-40-EVEN patch panels in the opposite
direction.
For installing the interleaver and deinterleaver module, refer to the “Installing
Cisco ONS 15216-MD-ID-50 Optical Interleaver and Deinterleaver Pluggable”
guide.

Fiber-Optic Connector Cleaning and Maintenance
Connector cleaning is required to maintain the performance of fiber-optic circuits.
It is important that both the LC/UPC connector at the end of the fiber-optic cable
and the mating bulkhead adapter on the front panel of the patch panel are clean
before the connection is made.
Warning Invisible laser radiation may be emitted from disconnected fibers or
connectors. Do not stare into beams or view directly with optical instruments.
Statement 1051
The following warning applies to disposal of chemicals and other materials used
to clean connectors and adapters:
Warning Ultimate disposal of this product should be handled according to all national
laws and regulations. Statement 1040
Note Before installing the fiber-optic cable, always perform the cleaning procedure for
cable connectors described in the following section. Whenever possible, inspect
each connector before connecting it to the mating bulkhead adapter on the front
panel.
Note The LC bulkhead adapters on the faceplate of the patch panel drawer are less
likely to get dirty if they are capped when not in use. Because the procedure for a
thorough cleaning of these adapters is complicated, Cisco recommends that you
use a commercially available cleaning kit and closely follow the instructions
included with the kit.
Customer Supplied Cleaning Materials
The Type A fiber optic connector cleaners (for example, CLETOP reel) are
recommended to clean the cable connectors, but are not supplied with the patch
panel.
