Proper Fiber Optic Cable Maintenance
mêçéÉê=cáÄÉê=léíáÅ=`~ÄäÉ=j~áåíÉå~åÅÉ=
To maintain the optimum operating conditions, fiber optic cable requires proper care and
handling. Please follow these basic guidelines:
Do not stretch, puncture, or crush the fiber optic cable.
Always maintain the minimum bend radius that is specified by the fiber optic cable
manufacturer. To avoid fractures of the glass, do not exceed these limits!
Avoid overtightening tie wraps that are placed around the cable. This action may
result in micro-bends, which in turn results in excess attenuation.
Always keep the dust caps on the cable ends until you make the connections. Re-
connect the dust caps when the cable is disconnected. Refer to the “Securing the
Dust Cap on the Fiber Optic Cable” section on page213 for more information.
Do not polish the fiber optic connectors with a cloth made of synthetic fibers. This
action will charge up the fiber and attract dust.
Protect the exposed ends from contact with all surfaces. Contact with hard
surfaces may scratch or chip the end, causing permanent damage.
Do not touch the exposed fiber ends with your finger, as this action will leave oil
residue on the fiber.
Do not use canned or compressed air to clean the connectors.
Clean each connector each time it is inserted into an adapter. Dirty connectors
will contaminate adapters. Clean all suspect surfaces with a Reel Cleaner, Stick
Cleaner, or optic grade alcohol and wipes.
To reduce condensation, ensure that the fiber end is dried after cleaning. Wipes
should be used once, and then discarded.
To ensure proper alignment, avoid tilting the connector during insertion. This
action also prevents damage or scratching to the fiber end.
Use the connector strain relief whenever pulling on the fiber cable. Pulling on the
fiber may damage the glass.
Always store protective covers in a clean container. Always clean contaminated
protective covers prior to use.
Note The minimum bend radius is usually 10-20 times the cable's
outer diameter.
