Handling Fiber Optic Cables

Guidelines for Handling Fiber Optic Cable

• Never touch the tip of a fiber connector. Cleanliness of the connector

ferrule (tip) is important for error-free transmission.

• Always place the dust caps onto the connectors immediately after

disconnecting.

• You can clean the ferrule tips on the connectors with ethyl alcohol.

• Fiber optic cables are often more easily installed and pulled than

copper because of their light weight and flexibility. However, take care

not to exceed the minimum bend radius or maximum tensile strength.

• Procedures for the repairing, splicing, or assembling of fiber optic

cables are available from fiber component manufacturers (many offer

training courses).

Specifications

At each end of a fiber optic cable is a Fiber Interface Module (FIM). At the

transmitting end, the FIM converts electrical signals into pulses of light to

be transmitted over the cable. At the receiving end, the FIM converts the

pulses of light back into electrical signals usable by the node.

The FIM connects the controller to a peripheral cabinet, or NSU. Each FIM

variant may be identified by its optical wavelength and fiber type (indicated

on the FIM faceplate). The same FIM variant must be used at each end of

a fiber optic cable. However, a node may be equipped with different FIM

variants to suit the length of each cable run.

See the SX-200 ICP Technical Documentation for Fiber Interface Module

specifications.

WARNING:FIBER OPTIC SOURCES EMIT INFRARED LIGHT

THAT IS INVISIBLE TO THE HUMAN EYE. NEVER LOOK

DIRECTLY INTO A SOURCE OR INTO THE END OF A FIBER

ENERGIZED BY A SOURCE BECAUSE IT CAN DAMAGE THE

RETINA. WHEN WORKING WITH RAW FIBER OPTIC CABLE,

BE CAREFUL OF THE FIBER ENDS OR SLIVERS THAT CAN

PUNCTURE THE SKIN OR CAUSE IRRITATION.
