A.2.6

Fiber Optic Cable Connections

This system normally operates as a Class I Laser Product

(no hazard), however during servicing operations, when

optical connectors are being connected, disconnected, or

handled without dust covers, it is possible to be exposed

to Class IIIB laser radiation which can cause eye damage.

Fiber optic connectors are delicate and can be damaged

easily by dirt or debris on the end of the connector. Keep

ﬁber optic connectors free of dust and debris by cleaning

the connector before and after use. Carefully clean the

ﬁber optic connector and cable ends with a cotton swab

dipped in alcohol or an alcohol wipe. Keep safety cap on

connectors when not in use.

The OC3 radio repeater cable carries DS1 clocks, data, and over-

head for two directions. OC3 ﬁber optic cables must be run sepa-

rately. If the repeater cable is not used, the embedded data in the

overhead must also be cabled individually. In this case, separate

cables must be run for MCS-11, audio, RS-232, and ELMC.
