Laser Safety
Introduction
This equipment contains an infrared laser that transmits intensity-modulated light and emits
invisible radiation.
Warning: Radiation
WARNINGS:
• Avoid personal injury! Use of controls, adjustments, or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
• Avoid personal injury! The laser light source on this equipment emits invisible laser
radiation. Avoid direct exposure to the laser light source.
• Avoid personal injury! Viewing the laser output with optical instruments (such as
eye loupes, magnifiers, or microscopes) within a distance of 100 mm may pose an eye
hazard.
•
Do not apply power to this equipment if the fiber is unmated or unterminated.
•
Do not stare into an unmated fiber or at any mirror-like surface that could reflect light that
is emitted from an unterminated fiber.
•
Do not view an activated fiber with optical instruments (e.g., eye loupes, magnifiers,
microscopes).
•
Use safety-approved optical fiber cable to maintain compliance with applicable laser safety
requirements.
Warning: Fiber Optic Cables
WARNING:
Avoid personal injury! Qualified service personnel may only perform the procedures in
this manual. Wear safety glasses and use extreme caution when handling fiber optic
cables, particularly during splicing or terminating operations. The thin glass fiber core
at the center of the cable is fragile when exposed by the removal of cladding and buffer
material. It easily fragments into glass splinters. Using tweezers, place splinters
immediately in a sealed waste container and dispose of them safely in accordance with
local regulations.
