PRECAUTIONS FOR HANDLING FIBEROPTIC CABLING

Precautions for Handling Fiberoptic Cabling

Observe the following precautions when handling fiberoptic

cabling:

• Fibers can be broken by poor handling, especially at

connectors.

• Dirt is harmful to fiberoptic connectors.

• Clean the ends of connectors with alcohol cleaning pads

before testing or reassembling equipment.

• Do not bend fibers too tightly, especially near connectors.

• Do not drop connectors on hard surfaces.

• Do not touch the ends of the connectors with your fingers.

• Do not leave connectors without dust caps.
