50 GHz/100GHz Optical Interleaver and De-interleaver Module
Introduction
This document explains how to install and operate the Cisco ONS 15216 50 GHz/100 GHz Optical Interleaver and De-Interleaver module used in the Cisco ONS 15216 FlexLayer four-slot shelf assembly. The FlexLayer product provides 50 GHz of channel spacing in Dense Wavelength Division Multiplexing (DWDM) systems.
Safety Information
Before you install, operate, or service the Cisco ONS 15216 50 GHz/100 GHz Optical Interleaver and De-interleaver module (hereafter referred to as the ONS 15216-ID-50), read the Cisco Optical Products Regulatory Safety and Compliance Information document for important safety information you should know before working with the system.
The ONS 15216-ID-50 is compliant with GR 1089, UL60950 /CSA 22.2 No. 60950-00, and IEC 60950.
Laser Radiation Emission Restrictions
The Class 1M Laser safety and warning label is affixed to the ONS 15216-ID-50 module and indicates that the product should never be used or installed in an optical network with emissions higher than Class IM.

Product Description
The ONS 15216-ID-50 is a C-band 50 GHZ/100 GHz module that operates in the Cisco ONS 15216 FlexLayer four-slot shelf assembly in 50-GHz channel spacing DWDM systems. The ONS 15216-ID-50 module can interleave and de-interleave signals and extract a fraction of the signals for monitoring purposes. These are some of the module's applications and uses:
•

Features
The ONS 15216-ID-50 is a modular component that provides signal interleaving and de-interleaving in 50-GHz channel spacing DWDM systems. It is optically and electrically passive and requires no temperature control. It uses fused fiber coupler technologies and a birefringent crystal technology platform. The module's ultra-low dispersion coupled with the wide bandwidth (Wideband 100 GHz) reduces the concerns of dispersion accumulation and bandwidth narrowing, making the ONS 15216-ID-50 ideal for Multi-OADM Metro ring or mesh-based architectures.
Some of the ONS 15216-ID-50 module's operating features include:

Functional Description
The ONS 15216-ID-50 module increases capacity by combining two optical data streams into a single, more densely spaced stream. The module 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 15216-ID-50 is a bidirectional module 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 design is illustrated in Figure 1.
Figure 1 Module Design
The interleaver 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 tap coupler enables aggregate 50-GHz-spaced transmitted optical channel spectrum monitoring at the output (TX-MON port).
The de-interleaver 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 tap coupler on each of the two Demux paths enables even (EVEN-MON port) and odd (ODD-MON port) channel signal spectrum monitoring.

Install the ONS 15216-ID-50 Module
The ONS 15216-ID-50 module operates in the Cisco ONS 15216 FlexLayer four-slot shelf assembly. The FlexLayer shelf can be installed anywhere in the rack (in other words, above or below the DWDM generating equipment), according to local site practice.
The 15216-ID-50 module is passive and requires no power cabling or connections. All connectors are on the front panel, which is equipped with LC/UPC bulkhead adapters. Fiber-optic cables equipped with the corresponding (LC/UPC) connector type are used. The module port numbers are labelled on the front panel, and port assignments are provided in Figure 2.
For more information about the FlexLayer product, see the Cisco ONS 15216 FlexLayer User Guide.
Figure 2 ONS 15216-ID-50 Module
Install the 15216-ID-50 Module in the ONS 15216 FlexLayer Shelf
The FlexLayer shelf assembly is 1 RU high and can be mounted in a 19- or 23-inch rack (2-way mounting brackets). The shelf assembly is houses four Add/Drop, Splitter/Combiner FlexLayer, or Interleaver/De-Interleaver modules, or two VOA FlexLayer modules. Figure 3 shows the FlexLayer shelf assembly and FlexLayer modules, including the ONS 15216-ID-50.

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 ONS 15216-ID-50 are clean before the connection is made.
Warning
The following warning applies to disposal of chemicals and other materials used to clean connectors and adapters.

•
When cleaning a paired cable connector (bulkhead mating adapter), always clean the mating adapter first.
If properly maintained (only used with clean, defect-free fiber connectors and capped when not in use), the mating adapter should not require cleaning. However, if you suspect the adapter is dirty, clean it by blowing with clean, dry, oil-free compressed air.

Operation
This section explains how to monitor performance on the ONS 15216-ID-50 module and how to remove the module from the Cisco ONS 15216 FlexLayer shelf assembly.
Monitoring Performance
The ONS 15216-ID-50 module uses Optical Test Access Port (TAP) devices to enable passive access and monitoring in the fiber-optic network. The TAPs enable network-based intrusion detection system sensors to operate efficiently without interruption. They send traffic data to a monitoring device by splitting the network signal, without introducing delay or changing the content or structure of the information contained in the packets. An OSA (Optical Spectrum Analyzer) or PM (Power Meter) can be used for optical power monitoring and optical analysis.
Table 3 shows the manufacturer-specified TAP split ratios for the TAP coupler's optical power in the ONS 15216-ID-50 module. The split ratio denotes the ratio of the TAP input signal to the output signal.

Note
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
