5.5 Repacking for Shipment
1. Tag the equipment showing owner’s name, address, and telephone number, together with a
detailed description of the problem.
2. Use the original shipping container if possible. If you do not have it, package the equipment in
a way to prevent shipping damage. Include the RMA inside the container and legibly print the
RMA number on the outside of the package, near the shipping address.
3. Insure the package.
NOTE:
Telect is not liable for shipping damage.
5.6 High Insertion Loss and the Importance of
Cleaning Connectors & Adapters
The major causes for poor performance (high insertion loss) are 1) attenuation due to too sharp
or too many close radius bends in the fiber cable, 2) loose connections, and 3) dirty connectors
or adapters. If you experience insertion loss greater than 25 dB, check for sharp bends and loose
connections. Clean all polished ferrules on the pigtail and both ends of the patch cord or jumper.
Though Telect includes dust caps with all adapters and connectors, it isn’t always possible to
ensure that fiber ferrules stay clean. If you need to clean connectors and adapters, Telect
recommends a commercially available system or solution. Special formulation for cleaning fiber
faces allows the commercial solvent to stay liquid long enough to dissolve impurities quickly and
thoroughly, yet evaporate quickly after wiping dry. Always allow the ferrules to air dry thoroughly
before reconnecting. You may use “canned air” to clean away debris initially, but don’t use an
aerosol after cleaning polished surfaces. Most aerosols contain contaminants.
If a commercial solution isn’t available, you may use
reagent-grade ethyl alcohol, nominally USP > 99%,
available at pharmacies.
Remove both connectors from the adapter.
1. Blow compressed gas through the adapter.
2. Moisten a lint-free wipe with the ethyl alcohol.
3. Wipe completely around the ferrule of the connector
twice. Repeat with a dry wipe.
4. Moisten the center area of a third wipe and pass the
face of the ferrule from the moistened area outward
toward the dry area. Do this twice.
5. Allow ferrule to air dry. Do not wipe the ferrule or allow it to touch anything after completion of
this step and before the ferrule is inserted into the adapter. Do not cover with a dust cap.
6. Insert the connector into the adapter.
7. Repeat Steps 2 through 7 for each connector.
