Precautions for Unenclosed Systems
During service, maintenance, or restoration, an optical fiber telecommunication system is considered
unenclosed. Under these conditions, follow the practices described below.
CAUTION!
Only authorized, trained personnel shall be permitted to do service, maintenance, and restoration.
1.
Avoid exposing the eye to emissions from unterminated, energized optical connectors at close
distances.
2.
Ensure that only authorized, trained personnel use optical test equipment during installation or
servicing.
3.
Turn off all laser sources before scanning a fiber with an optical test set.
4.
Keep all unauthorized personnel away from the immediate area of the optical fiber systems during
installation and service.
For guidance on the safe use of optical fiber communication systems in the workplace, consult
ANSI
Z136.2, American National Standard for Safe Use of Lasers
in the U.S. or outside the U.S.,
IEC-60825,
Part 2
.

Inspecting and Cleaning Fiber Optic
Connections
When connecting fibers to a back module, ensure that you do not touch the end of the fiber, or allow it
to become dirty. Small amounts of microscopic dust or other contaminants can seriously impair or
disable a fiber optic network. If you touch the end of a fiber prior to connecting it to the back module, or
otherwise allow it to become dirty, you must carefully inspect and clean the connection.
The table below lists some typical contaminants of a fiber optic connection. The inspection and cleaning
procedure begins on page 106 (see "Inspection and Cleaning Procedure" on page 123).
