Preface

Fiber optic server interfaces include:v Enterprise Systems Connection (ESCON®)

v Fibre Connection (FICON®)

v IntraSystem Coupling (ISC)

v OSA - Express® (Gbe) Gigabit Ethernet

v External Time Reference (ETR)

Each requires connectivity planning for differentfiber types and new fiber optic connectors.Similarly, connectivity requirements for every I/Odevice must be known because their connectorsmay not be the same as the connectors on a server,director, or switch. Fiber optic technology isevolving rapidly with new standards, small formfactor connectors, and enhanced fiber types. IBM®

offers a full range of services for optical cabling. Formore information, see Planning for Fiber Optic Links,GA23-0367.

Although there are a multitude of fiber opticconnectors, the components of those connectors arevirtually the same: the ferrule (male), theend-surface, and the coupler (female). Thispublication contains the cleaning procedures forthose fiber optic components.

Terms associated with Fiber Opticcabling include:1. Long wavelength laser (LX)

2. Short wavelength laser (SX)

3. Single Mode (SM)

4. Multimode (MM)

5. Mode Conditioning Patch cabling (MCP)

6. Fiber Optic SubAssembly (FOSA)

7. Fibre Channel Standard

8. Multi-Fiber Push-on (MPO)

Notes:

1. The optical ports of a transmitter-receiversubassemblies and laser source module shouldbe cleaned only when reduced opticalperformance exists.

2. If filtered dry air is available from a centralsource, then blow dry air over connectorferrules, end surfaces and inside couplers tohelp remove contamination.

Although figures in this publication showEnterprise System Connections (ESCON)components, these procedures apply to any fiberoptic components, including Fiber ChannelStandard (FCS).

Precautions

Please use the following precautions when handlingfiber optic equipment:

v Make sure the cable cutouts in the floor tiles havethe appropriate protective edging.

v Route the cables away from any sharp edges orprojections that could cut the outer jacket.

v Do not route the cables near unprotected steamor refrigeration lines.

v Do not coil the cable to less than a 96.0 mm (3.78in.) diameter.

v Do not bend the cable to less than a 50.8 mm (2.0in.) radius.

v Do not pull cables into position; place them.

v Do not grasp the cable with pliers.

v Do not attach a pull rope or wire to theconnectors.

v Always clean the connectors before installing,attaching, or replugging them to reduce linkloss.

v Do not remove the protective plugs orprotective covers until you are ready to cleanthe connectors and attach the cables to a device.

v Always leave the protective plugs andprotective covers on unused ports and cableconnectors.

v Connect the cable carefully to prevent damage tothe connector housing or the fiber optic ferrules.

v Before inserting the connector, make sure theconnector and receptacle keying are aligned.

viii Fiber Optic Cleaning Procedure

General cleaning procedures

Before performing any of the following procedures,read the statements in “Safety” on page iii.

v End-faces on fiber optic connectors must be freeof dust and other debris which could interferewith signal quality.

v To facilitate cleaning, use Cleaning Kit IBM PN46G6844 designed for both connectors and TRSs.This kit contains 18 lint free cloths, 10Microswabs, and 10 foam swabs.

v To facilitate cleaning of MPO/MTP styleconnectors, use Cleaning Cassette IBM PN12R7003, which has been specifically released forend-face cleaning.

v Compressed gas (ref CO2) may be used toremove dust. Compressed air is notrecommended due to possible oil contamination.

Note: If compressed air is used, keep the airnozzle approximately 50 millimeters (2 inches)from the component and continue blowing intothe component for 5 seconds.

v Dust caps applied over the connector end-faceshould always be used on unplugged connectors.

v The ONLY acceptable solution for cleaning isisopropyl alcohol. Do NOT use water forcleaning.

v For applications running at 8Gb/s and higher,additional cleaning steps may be required

Single coupler

Clean the inside of the coupler with a swabsaturated with isopropyl alcohol. Swabs can befound in Cleaning Kit PN 46G6844.

Note: Always check the area you have just cleanedto be sure it is free of lint or cotton fuzz.

2 Fiber Optic Cleaning Procedure

Duplex coupler

This procedure is used to clean any duplex coupler.

Clean the inside of the coupler with a swabsaturated with isopropyl alcohol. Swabs can befound in Cleaning Kit PN 46G6844.


General cleaning procedures 3

Wrap plug

This procedure is used to clean any wrap plug

1. Retract the wrap plug protective cover (ifpresent) to expose the ferrules. Keep theconnector protective cover retracted during thisprocedure.

2. Gently wipe the ferrule and the end-face surfaceof the wrap plug with an alcohol pad. Makesure the pad makes full contact with theend-face surface. Wait 5 seconds for the surfaceto dry.

Repeat three times with fresh surfaces of thealcohol pad. Allowing 5 seconds for the surfaceto dry between applications.


Protective plug

This procedure is used to clean any protective plug.Before performing this procedure, complete theappropriate procedure for cleaning the coupler ortransmitter-receiver subassembly (TRS) into whichthe protective plug will be inserted.

1. Gently wipe the plastic tip of the protectiveplug at least 5 times with an alcohol pad usinga pinch and twist motion. Give special attentionto the ridges at the ends of the tips.

2. Wait 5 seconds for the alcohol to dry

3. Immediately insert the protective plug into theTRS assembly or coupler. Make sure the twolatches are properly engaged with the shell.


Laser optical source module

Note: The optical ports of the laser source moduleshould be cleaned only when reduced opticalperformance or visible port contamination exists.

1. Remove the optical cover from the laser module.

2. Clean the inside of the optical port with a dryMicroswab. Rotate the swab once in a clockwisedirection.

3. Retry the measurement procedure. If opticalperformance is still not improved, replace themodule.


Fiber optic cable connector

Use this general procedure to clean any fiber opticcable connector. Repeat these steps as necessary.

1. Gently wipe endface with lint-free pad in onedirection.

2. Using a can with compressed gas held uprightand approximately 2 inches from the connectorend, release a stream of gas on the connectorendface for no more than 5 seconds.

3. Gently wipe the ferrule and the end-face surfaceof the connector with an alcohol pad. Makingsure the pad makes full contact with theend-face surface. Wait 5 seconds for the surfaceto dry.

Single connector:

Duplex connector:

Repeat three times with fresh surfaces of thealcohol pad. Allowing 5 seconds for the surfaceto dry between applications.


4. For applications that may require additionalcleaning steps (e.g. data rates @8Gb/s higher);use 2 applications of isopropyl alcohol wipesmaintaining contact with the ferrule surface for5-10 seconds. .


Fiber optic transmitter-receiversubassembly (TRS)

Use this general procedure to clean a fiber opticTRS.

Note: The optical ports of the TRS should becleaned only when reduced optical performance orvisible port contamination exists. If problems existwith the function of the TRS assembly, use thisprocedure as a last resort to clean the ports beforereplacing the card.

1. Clean the inside of the optical port with a dryMicroswab. These can be found in Cleaning kitPN 46G6844.

2. Compressed gas may be used in instanceswhere additional cleaning is required. If used, itshould be applied for no more than 3-4 seconds.Compressed air is not recommended due to anaccumulation of oils. It if is used, a lint freeswab should be used to wipe the port aftercleaning.



Fiber optic cable and TRS cleaningprior to card replacement

This procedure is used to clean both the fiber opticconnector and TRS if the fiber optic card appears tobe failing because of problems with the TRS or theoptical connector (such as optical power levelsmeasurements out of specification). Refer toMaintenance Information for Fiber Optic Links(ESCON, FICON, Coupling Links, and Open SystemAdapters), SY27-2597, for the proper measurements.

v Card Test Failure--Fiber Optic Duplex Connector

Clean the Duplex connector using the procedurein “Fiber optic cable connector” on page 7.

v TRS Failure

Clean the TRS using the procedure in “Fiberoptic transmitter-receiver subassembly (TRS)” onpage 9.

After cleaning the fiber optic component, measurethe optical power level. Replace the card as a failingcomponent if the measurements are out ofspecification limits.

For applications running @ 8Gb/s and higher: if thecleaning process outlined above does not result insufficient optical power levels, applying an indexmatching optical gel to the end-face may be used tobring sufficient results.
