Installing the Cisco NCS 2000 Series Passive Optical Modules
Introduction
This document explains how to install and operate the Cisco NCS 2000 Series passive optical modules, the
fiber shuffle, and the MPO fan-out unit. The Cisco NCS 2000 Series encompasses platforms from Cisco NCS
2002 onwards.
The passive optical modules are used to build the optical network system. The fiber shuffle and MPO fan-out
unit mechanically holds 14 and 10 passive optical modules respectively, thus enabling interconnection of flex
spectrum ROADM nodes that contain 16-WXC or SMR-FS cards.
The passive optical modules, fiber shuffle, and MPO fan-out unit can be installed on:
• 19-inch (482.6 mm) or 23-inch (584.2 mm) EIA standard racks
• 19-inch (482.6 mm) IEC rack
• 600 mm x 600 mm or 600 mm x 300 mm ETSI rack
The following table lists the PIDs of the fiber shuffle and MPO fan-out unit:

Rack Mounting Bracket
All passive optical modules, except for the 8-degree mesh patch panel module, are installed using the rack
mounting bracket (NCS2K-MF-1RU=). The rack mounting bracket is 19 inches (482.6-mm) wide and can
be mounted on a 19-inch (482.6-mm) ANSI or an IEC equipment rack. However, by using a pair of external
brackets (either straight or Z-shaped), it can also be mounted on a 23-inch (584.2-mm) ANSI, a 600 x 600
mm (23.6 x 23.6-inch), or a 600 x 300 mm (23.6 x 11.8-inch) equipment rack.
The Cisco NCS passive optical modules size can be single slot or double slot.
• Single slot cassette units: NCS2K-MF-4X4-COFS=, NCS2K-MF-MPO-8LC=, NCS2K-MF-DEG-5=,

NCS2K-MF-8X10G-FO=.
The rack mounting bracket has two cut outs.
• Each cut out (left or right) can accommodate two single slot cassettes, for a total of four single slot
cassettes in the rack mounting bracket.
• Each cut out (left or right) can also accommodate one double slot cassette, for a total of two double slot
cassettes in the rack mounting bracket.
• If a rack mounting bracket slot remains empty, it can be filled with a blank-slot filler panels.
Diagram 1 in the following figure indicates the rack mounting bracket installed on a 19-inch ANSI or IEC
equipment rack.
Diagram 2 in the following figure indicates the rack mounting bracket installed on a 23-inch ANSI equipment
rack.

The MPO-8 and MPO-16 cables have a similar physical appearance. Hence, when connecting the cables to
the MPO-8 or MPO-16 adapters, use only MPO-8 and MPO-16 cables to connect to their respective adapters
because the optical signals will not pass through the module if a wrong cable is used.
