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:

• A set of photodiodes are included on selected ports of each module for optical power monitoring.

•USB communication channel can be used to retrieve the optical power levels monitored by the photodiodes

and the inventory and insertion loss (IL) data of the optical paths stored in the modules. The USB channel

can also be used to activate electrical actuators or LEDs present on the front panel of the module.

Safety Information

Before you install, operate, or service the passive optical modules, you must read the Regulatory Compliance

and Safety Information for Cisco NCS 2000 Series document for important safety information and warning

translations.

The passive optical modules are compliant with the GR 1089, UL60950 /CSA 22.2 No. 60950-00, and IEC

60950 standards.

Laser Radiation Emission Restrictions

The Class 1M Laser safety and warning label affixed to the passive optical modules indicate that the product

should never be used or installed in an optical network with emissions higher than Class 1M.

Class 1M laser radiation when open. Do not view directly with optical instruments. Statement 281

Warning

Safety Information

Laser Safety During Operation

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or

view directly with optical instruments. Statement 1051

Warning

Electrical Safety

The passive optical modules are optically and electrically passive and require no electrical connections. No

electrostatic discharge (ESD) or other electrical safety considerations apply.

Fiber Shuffle

The MF-6RU unit is six RU high and can be used to interface 14 single slot passive optical modules with the

NCS 2015 ECU. It contains a USB 3.0 hub that consolidates all USB 2.0 connections between the passive

optical modules units and the NCS 2015 ECU using a single USB cable. It allows connections between line

cards and optical passive modules units using simple cabling. The slots are covered by blank units. The

MF-6RU unit is shipped with USB connectors connected to the corresponding blank units. A plastic transparent

door can be installed in front of the unit for fiber and cable management. Mounting brackets are shipped with

the unit.

MPO Fan-out Unit

The MF10-6RU unit is six RU high and can be used to interface 10 double slot passive optical modules with

the NCS 2015 ECU. It contains a USB 3.0 hub that consolidates all USB 2.0 connections between the passive

optical modules units and the NCS 2015 ECU using a single USB cable. It allows connections between line

cards and optical passive modules units using simple cabling. It also has an additional USB 3.0 port on its

faceplate that allows it to be connected to only one MF10-6RU unit.

The slots are covered by blank units and USB connectors are connected to the corresponding blank units. A

plastic transparent door can be installed in front of the unit for fiber and cable management. Mounting brackets

This procedure describes the steps to install the MF-6RU or MF10-6RU unit on the ANSI or ETSI equipment

rack.

Procedure

Step 1 For a 23-inch ANSI or 21-inch ETSI rack installation, mount the four brackets on the MF-6RU unit or

MF10-6RU unit and:

a) Place the mounting bracket flush against the MF-6RU or MF-0-6RU unit.

b) Align the mounting bracket screw holes against the MF-6RU or MF10-6RU unit screw holes.

c) Insert the M6 screws and tighten them.

d) Repeat steps 1a through 1c to mount the remaining three brackets on the unit.

Step 2 Install the MF-6RU or MF10-6RU unit on the appropriate rack equipment:

a) Lift the MF-6RU or MF10-6RU unit to the desired position in the rack.

b) Align the screw holes on the mounting brackets with the mounting holes in the rack.

For a 19-inch ANSI rack installation, external mounting brackets are not installed on the MF-6RU

or MF10-6RU unit. The unit is mounted directly on the equipment rack using screws and washers.

Note

c) Insert the screws and tighten them.
