Safety Precautions for Enclosed Systems
Under normal operating conditions the FT-2000 OC-48 Lightwave System is
completely enclosed; nonetheless, the following precautions should be observed:
â– Because of the potential for eye damage, technicians should neither
disconnect any lightwave cable nor splice and stare into the optical
connectors terminating the cables.
â– Under no circumstance should lightwave/lightguide operations be
performed by a technician before satisfactorily completing an approved
training course.
â– Since viewing lightwave emission directly with an optical instrument, such
as an eye loupe, greatly increases the risk of eye damage, an appropriate
label must appear in plain view on the front of the main frame or lightguide
termination/interconnection equipment. The label shall read as follows:
NOTICE: UNTERMINATED OPTICAL CONNECTORS MAY EMIT LASER
RADIATION. AVOID DIRECT EXPOSURE TO THE BEAM. DO NOT
VIEW THIS BEAM WITH OPTICAL INSTRUMENTS.
A warning label (Figure 1) is provided on the filter panel of the Enhanced High-
Speed Shelf and on the right front of the High Speed Shelf and Repeater Shelf–
System Controller. The word DANGER is in central office white lettering on a red
background. The text of the warning label is in black lettering on a white
background.
