Handling Equipment Precautions and Guidelines
Handling Fiber-Optic Cables
Fiber-optic cables require special handling and connecting
procedures. They can be damaged when handled or routed
improperly.
If you plan to have a front cover installed on your FSP 3000 C shelf
and will be using cables with MPOconnectors, you must have the
front cover extension installed. To determine if your shelf
rack/cabinet configuration supports front covers and extensions, as
well as more information about accessory installation requirements,
see Accessory Installation Requirements.
To avoid damaging the glass fiber, observe the following guidelines:
l Fiber-optic cables should never be bent at sharp angles (less than a 30 mm [1.2 in.]
radius). Do not exceed the values for minimum bend radii and maximum tensile loading
(depends on fiber-optic cable type).
l Make sure to only use fiber-optic cables with a flexible bending protection.
l Do not knot or over flex fiber-optic cables.
l Avoid mechanical stress by routing unsupported fiber-optic cables over short
distances only. Frequent mechanical stress can cause progressive degeneration of
fiber-optic cables.
l Avoid tightening or pressuring fiber-optic cables.
l Avoid twisting or crossing one cable over another.
l Avoid excess cable length. Use a spiral wrap or equivalent.
l Do not tie fiber-optic cables together with a cable clamp or tie strap.
l Do not stand on fiber-optic cables. Keep the cables off the floor.
l Do not allow a greater static load on any section of the fiber-optic cable.
l Do not pull fiber-optic cables too hard. When connecting or disconnecting a fiber-optic
connector, hold the knob of the (plastic) movable part of the plug casing. The cable
should be pulled from a point several centimeters or inches away from the connector.
l The most vulnerable areas of a fiber-optic cable are its connector plugs. Use extreme
care when removing or installing fiber-optic connector plugs to avoid damaging the
connector housing or scratching the end-face surface of the fiber.
l Put protective caps on fiber-optic connectors when not in use.
l Only remove the protective caps right before you connect a fiber-optic cable.
l Never use tools when connecting or disconnecting fiber-optic cables. Excessive force
can damage or mis-align the connection system.
l Never place tools or other hard and heavy items on top of the fiber cable.
l Store unused fiber-optic cables in a cabinet or on a cable rack.
l Clean fiber-optic equipment as described in Inspecting and Cleaning Fiber-optic
Connectors and Receptacles. Never wipe an optical fiber with abrasive material or
organic solvents such as acetone.
l Keep power cables, data cables, and fiber-optic cables clear of foot traffic. Route
cables in vertical cable ducts on the rack under the floor, through the ceiling, or in
protective channels.
l Never eat, drink, or smoke when working with fibers.
