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:

Extends existing network capacity

Provides low cost future proofing of network capacity

Allows for non-traffic affecting capacity upgrade

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:

Low dispersion

Low insertion loss

High channel isolation

Wide clear bandwidth

Full C-band coverage

Athermal design

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.

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 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 ONS 15216-ID-50 front panel.



Note The LC bulkhead adapters on the ONS 15216-ID-50 front panel 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 and involves opening the ONS 15216-ID-50 module, Cisco recommends that you use a commercially available cleaning kit and closely follow the instructions included with the kit. Only a simple, routine cleaning procedure for these adapters that can be easily performed by the customer is described here.


Customer Supplied Cleaning Materials

These cleaning materials are recommended but are not supplied with the ONS 15216-ID-50 module:

Reagent grade ethyl alcohol in an alcohol dispenser

Lint free laboratory wipes

Clean, dry, oil-free compressed air

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.

Clean the Bulkhead Mating Adapters


Step 1 Read the manufacturer instructions to properly use the compressed air can.


Note Improper use of compressed air may cause more contamination to the part being cleaned and defeat the purpose of cleaning the bulkhead mating adapters.


Step 2 Before blowing the adapter clean, release a short blast of compressed air to remove any dust inside the nozzle of the compressed air can.

Step 3 Blow three to four short blasts of air into the adapter housing to remove any dust.


Note Always keep unused adapter ports and fiber connectors capped with a clean dust cap.



Clean Fiber-Optic Cable Connectors


Step 1 Fold a clean wipe several times to get a pad of six to eight layers of material.

Step 2 Remove the protective cap on the LC/UPC optical fiber cable connector.

Step 3 Dampen (but do not soak) a corner of the pad with alcohol using the alcohol dispenser.

Step 4 Firmly press the tip of the ferrule into the alcohol-moistened area of the wipe. Pinch the wipe firmly with your fingers against the ferrule and twist the ferrule to firmly wipe the ferrule. Repeat this step three times, using a clean alcohol-moistened area each time.


Note The design of the LC connector makes it difficult to clean the entire perimeter of the ferrule, because only a small portion close to the ferrule tip is accessible. Clean the tip of the ferrule and the entire accessible perimeter. Keep the fiber connector capped at all times when not in use.


Step 5 Press the ferrule tip into a clean, dry spot on the wipe and perform the pinch-and-twist procedure described in Step 4 once.

Step 6 Discard the used wipe.

Step 7 (Optional) A couple of short blasts of clean, dry, oil-free compressed air should remove any tissue fragments that may have been deposited on the ferrule during cleaning.

Step 8 Whenever possible, inspect the ferrule end-face to ensure that the cleaning procedure effectively removed the dust/dirt from the ferrule and that no cleaning-induced damages are present.

Step 9 If the ferrule end-face is still dirty, repeat Steps 1 through 8.

Step 10 If the ferrule shows damages (for example, scratches or pits across the fiber core), replace the fiber patch cord with a new one equipped with a defect-free connector.

Defects on the fiber cable connector are likely to damage the mating connector inside the ONS 15216-ID-50, which results in more costly repairs.

Step 11 If the ferrule end-face is clean and damage-free, place the connector into the corresponding clean mating adapter on the ONS 15216-ID-50 front panel following the instructions in the next section.


Install and Route Fiber-Optic Cables


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



Caution When connecting an optical fiber patch cord between the ONS 15216-ID-50 and the optical card ports in the ONS 15454, use the electrostatic discharge wristband supplied with the ONS 15454. Plug the wristband into the ESD jack on the lower right front side of the ONS 15454.


Note Always clean all fiber connectors thoroughly before making the connection with the mating adapter. Very small particles can permanently damage the end of the mating fiber inside the ONS 15216-ID-50 module, which makes regular cleaning imperative. For cleaning instructions see "Fiber Optic Connector Cleaning and Maintenance" section.



Note The ONS 15216-ID-50 front panel features LC/UPC bulkhead adapters. Always use fiber-optic cables equipped with the corresponding (LC/UPC) connector type. Using any other type of connector results in damage to the connector and/or adapter.



Step 1 Place the LC/UPC cable connector in front of the corresponding bulkhead adapter on the front panel of the ONS 15216-ID-50.

Step 2 Align the keyed ridge of the cable connector with the slot in the receiving adapter.

Step 3 Gently push the cable connector into the adapter until you hear a click, which indicates that the latching system is engaged.

Step 4 Open the fiber guide by pulling the fiber guide locker on the appropriate side of the front panel. The top is secured by a spring-ball screw that enables the fiber guide locker to be easily opened or closed.

Step 5 Route the fiber cables through the fiber guide and lock them into place using the fiber guide locker.


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.

Cisco Product Security Overview

Cisco provides a free online Security Vulnerability Policy portal at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

From this site, you will find information about how to:

Report security vulnerabilities in Cisco products.

Obtain assistance with security incidents that involve Cisco products.

Register to receive security information from Cisco.

A current list of security advisories, security notices, and security responses for Cisco products is available at this URL:

http://www.cisco.com/go/psirt

To see security advisories, security notices, and security responses as they are updated in real time, you can subscribe to the Product Security Incident Response Team Really Simple Syndication (PSIRT RSS) feed. Information about how to subscribe to the PSIRT RSS feed is found at this URL:

http://www.cisco.com/en/US/products/products_psirt_rss_feed.html

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability in a Cisco product, contact PSIRT:

For Emergencies only —  security-alert@cisco.com

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

For Nonemergencies —  psirt@cisco.com

In an emergency, you can also reach PSIRT by telephone:

1 877 228-7302

1 408 525-6532


Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been encrypted with PGP versions 2.x through 9.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.

If you do not have or use PGP, contact PSIRT at the aforementioned e-mail addresses or phone numbers before sending any sensitive material to find other means of encrypting the data.


Obtaining Technical Assistance

Cisco Technical Support provides 24-hour-a-day award-winning technical assistance. The Cisco Technical Support & Documentation website on Cisco.com features extensive online support resources. In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.

Cisco Technical Support & Documentation Website

The Cisco Technical Support & Documentation website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, at this URL:

http://www.cisco.com/techsupport

Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

http://tools.cisco.com/RPF/register/register.do


Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support & Documentation website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.


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: 1 800 553-2447

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.
