Installing the Cisco ONS 15216-MD-48-CM Interleaver (Coupler) and Deinterleaver Pluggable

This document explains how to install and operate the Cisco ONS 15216-MD-48-CM interleaver (coupler) and deinterleaver pluggable.

Overview of the Cisco ONS 15216-MD-48-CM Interleaver and Deinterleaver Pluggable

The Cisco ONS15216-MD-48-CM=: 50 GHz/100 GHz C-band interleaver and deinterleaver pluggable provides signal interleaving and deinterleaving in 50-GHz channel spacing DWDM systems. It operates inside the ONS 15216-MD-40, ONS 15216-EF-40, or ONS 15216-MD-48 odd and even patch panels.

For installing the 15216-MD-40 patch panel, refer to the "Installing the Cisco ONS 15216-MD-40-ODD and 15216-MD-40-EVEN Mux/Demux Patch Panels" guide. For installing the 15216-EF-40 patch panel, refer to the "Installing the Cisco ONS 15216-EF-40-ODD and 15216-EF-40-EVEN Mux/Demux Patch Panels" guide. For installing the 15216-MD-48 patch panel, refer to the "Installing the Cisco ONS 15216-MD-48-ODD and 15216-MD-48-EVEN Mux/Demux Patch Panels"

The ONS 15216-MD-48-CM interfaces between the following:

  • 15216-MD-40 odd/even patch panels and 80 channels of wavelengths
  • 15216-EF-40 odd/even patch panels and 80 channels of wavelengths
  • 15216-MD-48 odd/even patch panels and 96 channels of wavelengths

The advantages of installing the ONS15216-MD-48-CM are:

  • Extends existing network capacity.
  • Provides low-cost future proofing of network capacity.
  • Allows for non-traffic affecting capacity upgrade when the patch panel is equipped with the ONS15216-MD-48-CM interleaver and deinterleaver pluggable at first installation.

Features

The ONS 15216-MD-48-CM is optically and electrically passive and requires no temperature control. It uses fused fiber coupler and birefringent crystal technologies.

The operating features of the ONS 15216-MD-48-CM include:
  • Low dispersion
  • Low insertion loss
  • High channel isolation
  • Wide clear bandwidth
  • Full C-band coverage
  • Interleave and Deinterleave 80 or 96 channels
  • Athermal design

Functional Description

The ONS 15216-MD-48-CM pluggable increases the network capacity by combining two optical data streams into a single, more densely spaced stream. This pluggable can be used in mux mode to combine two 100 GHz optical signal streams into one 50 GHz stream, or in demux mode to separate the 50 GHz stream into two 100 GHz streams.

The ONS 15216-MD-48-CM is a bidirectional pluggable in which the mux and demux functions are implemented in two different sections to enable signals flowing in opposite directions to be managed separately. This functionality is illustrated in the following figure.

Figure 1. Functional Description of the ONS 15216-MD-48-CM Interleaver and Deinterleaver Pluggable

The interleaver (3dB optical coupler) in the mux section combines the even and odd channel signals at 100 GHz spacing (EVEN-RX and ODD-RX ports, respectively) into the 50 GHz channel spacing signal.

The deinterleaver in the demux section separates the 50 GHz channel spacing signal into even and odd channel signals of 100 GHz spacing (EVEN-TX and ODD-TX ports, respectively).

The interleaver and deinterleaver module is plugged inside the patch panel and is interconnected with another patch panel of a different grid (odd or even).

Optical Interconnections

The optical interconnections between the odd patch panel, ONS 15216-MD-48-CM interleaver and deinterleaver pluggable and the even patch panel is shown in the following figure:

          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 optical mating adapter on the front panel.



          Note


          The LC optical mating adapter on the faceplate of the device is less likely to get dirty if it is capped when not in use. On some devices, the optical mating adapter has a shutter. The shutter automatically closes when the LC/UPC connector is disconnected. This prevents entry of dirt.

          The procedure for a thorough cleaning of these adapters is complicated. 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 device.

          If properly maintained (only used with clean, defect-free fiber connectors and capped when not in use), the mating adapter would not require cleaning. However, if you suspect the adapter is dirty, clean it by using the CLETOP stick swab.


          Note


          For multifiber cable assemblies, use specific cleaning tools or materials designed for the assembly type.


          Cleaning the Optical Mating Adapter

          Procedure
            Step 1   Read the cartridge cleaning instructions (provided by the manufacturer) to insert the cartridge cleaning tip into the optical mating adapter.
            Step 2   Slide the lever on the cartridge to swipe the mating surface.
            Note   

            Always keep unused adapter ports and fiber connectors capped with a clean dust cap. The optical mating adapters that have shutter need not be capped.


            Cleaning Fiber-Optic Cable Connectors

            The tools required to clean fiber connectors are:
            • Inspection microscope
            • Type A Fiber Optic Connector Cleaner (CLETOP reel)
            • Optical swab
            • Optical receiver cleaning stick
            Procedure
              Step 1   Using an inspection microscope, inspect each fiber connector for dirt, cracks, or scratches.
              Step 2   Replace any damaged fiber connectors.
              Note    Replace all dust caps whenever the equipment is unused for 30 minutes or more.
              Caution   

              Do not reuse optical swabs. Keep unused swabs off of work surfaces.

              Step 3   Clean the fiber connectors with CLETOP reel:
              1. If present, remove the dust cap from the fiber connector.
              2. Press the lever down to open the shutter door. Each time you press the lever, you expose a clean wiping surface.
              3. Insert the connector into the CLETOP cleaning cassette slot, rotate one-quarter turn, and gently swipe downwards.
              4. Use an inspection microscope to inspect each fiber connector for dirt, cracks, or scratches. If the connector is not clean, repeat the above sub-steps.
              5. Insert the fiber connector into the applicable adapter or attach a dust cap to the fiber connector.
              Note    Before replacing a dust cap on a connector, verify that the dust cap is clean. To clean the dust cap, wipe the outside of the cap using a dry, lint-free wipe and the inside of the dust cap using a CLETOP stick swab (14100400).
