power is transferred in the fibers and is not accessible. Each optical transmitter and
each optical amplifier is assigned to a hazard level according to IEC 60825–2. This
hazard level is based on radiation that could become accessible under reasonable
foreseeable circumstances, e.g. disconnected fiber connector, fiber cable break.
NOTICE
Hazard Level
The hazard level of the optical transmitter is: 1M: eye safe for normal viewing
(without optical aids).
Where possible, optical transmission or test equipment should be shut down, put into a low power state of
disconnected before any work is completed on exposed fiber, connectors, etc.
Check optical power in a fiber using a calibrated optical power meter.
If it is necessary to look at fibers or connectors: Ensure that the fibers do not transmit optical power. There-
fore, use a calibrated optical power meter.
Do not stare directly into the beam and do not use any unapproved collimating device to view the fiber ends
or connector faces. Always use approved eye protection equipment if hazardous level requires. Do not point
fiber ends at other people.
If the work to be carried out requires the use of eye protection, only use equipment which has been tested and
approved for the wavelengths involved.
Any single or multiple fiber ends or ends found not to be terminated with power levels exceeding hazard level
1 should be individually or collectively covered when not being worked on. Use only covers or covering ma-
terial with sufficient attenuation of the optical power at the wavelength concerned. Sharp ends should not be
exposed.
When using optical test cords, the optical power source shall be the last to be connected and the first to be
disconnected.
Do not make any unauthorized modifications to any optical fiber system or associated equipment.
Replace damaged optical safety labels or attach new labels if labels are missing.
Use test equipment of the lowest class necessary and practical for the task. Do not use test equipment of a
higher class than the location hazard level.
