Handling Optical Connectors and Fiber Optic Lines

Optical connectors are precision components, and must be handled accordingly. In order
to guarantee that the optical connectors function without problem:

FCC Registration

The installation manual for an intentional or unintentional radiator shall caution the user
that changes or modifications not expressly approved by the party responsible for com-
pliance could void the user's authority to operate the equipment.

When inserting and removing shelves and when transporting them, take their weight
into consideration.
Cables may never be disconnected by pulling on the cable. Disconnec-
tion/connection may only be undertaken by pushing in/pulling out the connector in-
volved.
Open optical connections must use a protective cap under all circumstances to pro-
tect against physical damage and dirt.
Before making connections, use isopropyl alcohol and non-fibrous cellulose to clean
the faces of the connectors.
Avoid impact stresses when handling connectors.
Physical damage to the faces of optical connections impair transmission quality
(higher attenuation).
Avoid a bend radius in excess of 30 mm for fiber optic links.
Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment may be greater than room
ambient. Therefore, consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature (Tma) specified by
the manufacturer.
Reduced Air Flow - Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
Mechanical Loading - Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
Circuit Overloading - Consideration should be given to the connection of the equip-
ment to the supply circuit and the effect that overloading of the circuits might have on
overcurrent protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
Reliable Earthing - Reliable earthing of rack-mounted equipment should be main
tained. Particular attention should be given to supply connections other than direct
connections to the branch circuit (e.g. use of power strips).
