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 different
fiber types and new fiber optic connectors.
Similarly, connectivity requirements for every I/O
device must be known because their connectors
may not be the same as the connectors on a server,
director, or switch. Fiber optic technology is
evolving rapidly with new standards, small form
factor connectors, and enhanced fiber types. IBM®
offers a full range of services for optical cabling. For
more information, see Planning for Fiber Optic Links,
GA23-0367.
Although there are a multitude of fiber optic
connectors, the components of those connectors are
virtually the same: the ferrule (male), the
end-surface, and the coupler (female). This
publication contains the cleaning procedures for
those fiber optic components.
Terms associated with Fiber Optic
cabling 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-receiver
subassemblies and laser source module should
be cleaned only when reduced optical
performance exists.

2. If filtered dry air is available from a central
source, then blow dry air over connector
ferrules, end surfaces and inside couplers to
help remove contamination.
Although figures in this publication show
Enterprise System Connections (ESCON)
components, these procedures apply to any fiber
optic components, including Fiber Channel
Standard (FCS).
Precautions
Please use the following precautions when handling
fiber optic equipment:
v Make sure the cable cutouts in the floor tiles have
the appropriate protective edging.
v Route the cables away from any sharp edges or
projections that could cut the outer jacket.
v Do not route the cables near unprotected steam
or refrigeration lines.
v Do not coil the cable to less than a 96.0 mm (3.78
in.) diameter.
v Do not bend the cable to less than a 50.8 mm (2.0
in.) 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 the
connectors.
v Always clean the connectors before installing,
attaching, or replugging them to reduce link
loss.
v Do not remove the protective plugs or
protective covers until you are ready to clean
the connectors and attach the cables to a device.
v Always leave the protective plugs and
protective covers on unused ports and cable
connectors.
v Connect the cable carefully to prevent damage to
the connector housing or the fiber optic ferrules.
v Before inserting the connector, make sure the
connector and receptacle keying are aligned.

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 free
of dust and other debris which could interfere
with signal quality.
v To facilitate cleaning, use Cleaning Kit IBM PN
46G6844 designed for both connectors and TRSs.
This kit contains 18 lint free cloths, 10
Microswabs, and 10 foam swabs.
v To facilitate cleaning of MPO/MTP style
connectors, use Cleaning Cassette IBM PN
12R7003, which has been specifically released for
end-face cleaning.
v Compressed gas (ref CO2) may be used to
remove dust. Compressed air is not
recommended due to possible oil contamination.
Note: If compressed air is used, keep the air
nozzle approximately 50 millimeters (2 inches)
from the component and continue blowing into
the component for 5 seconds.
v Dust caps applied over the connector end-face
should always be used on unplugged connectors.
v The ONLY acceptable solution for cleaning is
isopropyl alcohol. Do NOT use water for
cleaning.
v For applications running at 8Gb/s and higher,
additional cleaning steps may be required

4. For applications that may require additional
cleaning steps (e.g. data rates @8Gb/s higher);
use 2 applications of isopropyl alcohol wipes
maintaining contact with the ferrule surface for
5-10 seconds. .
8
Fiber Optic Cleaning Procedure
Fiber optic transmitter-receiver
subassembly (TRS)
Use this general procedure to clean a fiber optic
TRS.
Note: The optical ports of the TRS should be
cleaned only when reduced optical performance or
visible port contamination exists. If problems exist
with the function of the TRS assembly, use this
procedure as a last resort to clean the ports before
replacing the card.
1. Clean the inside of the optical port with a dry
Microswab. These can be found in Cleaning kit
PN 46G6844.
2. Compressed gas may be used in instances
where additional cleaning is required. If used, it
should be applied for no more than 3-4 seconds.
Compressed air is not recommended due to an
accumulation of oils. It if is used, a lint free
swab should be used to wipe the port after
cleaning.
Note: Always check the area you have just cleaned
to be sure it is free of lint or cotton fuzz.
General cleaning procedures
9
Fiber optic cable and TRS cleaning
prior to card replacement
This procedure is used to clean both the fiber optic
connector and TRS if the fiber optic card appears to
be failing because of problems with the TRS or the
optical connector (such as optical power levels
measurements out of specification). Refer to
Maintenance Information for Fiber Optic Links
(ESCON, FICON, Coupling Links, and Open System
Adapters), SY27-2597, for the proper measurements.
v Card Test Failure--Fiber Optic Duplex Connector
Clean the Duplex connector using the procedure
in “Fiber optic cable connector” on page 7.
v TRS Failure
Clean the TRS using the procedure in “Fiber
optic transmitter-receiver subassembly (TRS)” on
page 9.
After cleaning the fiber optic component, measure
the optical power level. Replace the card as a failing
component if the measurements are out of
specification limits.
For applications running @ 8Gb/s and higher: if the
cleaning process outlined above does not result in
sufficient optical power levels, applying an index
matching optical gel to the end-face may be used to
bring sufficient results.
