Table 8.1
Guidelines for Handling Fiber Optic Cable
Guideline Description
Minimum bend Observe the minimum fiber cable bend radius specified.
radius
Skin Contact Do not touch the ends of the fiber optic strands. The fiber can break
easily and pierce your skin.
· Do not let the ends of a fiber optic cable come into contact with
Contamination
dust, dirt, or other contaminants.
· Clean contaminated ends with a soft, clean, lintless cloth and
alcohol.
Protective caps Attach protective caps onto fiber ports when they are disconnected.
Installation Train personnel on usage of the installation tools to place and
training terminate fiber cable, including training on hand-held tools, tension
meters, optical power meters, cleaners, and adhesives.
Installation Observe all local regulations for installation including personal safety
regulations equipment and the guidelines for its use.
Proper disposal Always dispose of fiber waste. Disposing of fiber waste prevents the
contamination of clothes, fingers, or eyes of glass fragments. Do not
leave pieces of fiber cable on your work surfaces.
· Review cable specifications for distances and required connectors.
Specifications
· Review all cable parameters and specifications before installation.
Make sure that you have the proper amount of connectors and
installation equipment. Never attempt to use non-compatible
connectors and installation tools.
· Observe the maximum pulling tensions. Do not pull directly on fiber
Pulling tensions
or force cable into a bend radius less than the maximum allowable.
This will crack the glass and result in optic loss.
· The cable should never be pulled at a force greater than the
maximum allowable pulling tension. Excessive loads from bending
or pulling may cause fiber damage. Use a running line tension
meter to determine the pulling tension applied during cable
placement.
· Never allow tight loops, knots, kinks, or tight bends in the cable.
· The cable should not be pulled around any bends smaller than 20
times the cable diameter when under load and 10 times the cable
diameter at no load.
· Entrance in and out of metal pull boxes must be smooth as not to
damage the cable sheath

surface. The glass is very small and can penetrate
your skin easily.
