4. Safety of laser product
Optical amplifier module contains laser diode source. This device is rated under IEC60825-1
“Safety of Laser Products”,
Part 1: Equipment classification and requirements as CLASS 3R
laser product
.
When operating the equipment note the following:
Most fiber optic laser wavelengths are totally invisible to the eye and will cause permanent eye damage.
Never look into the end of a fiber on a powered device through a magnifying device (microscope, eye loupe, magnifying
glass, etc.). Before using such devices always double check that power is disconnected or, if possible, completely disconnect
the unit from any power source.
To verify the light output always use an instrument, such as an optical power meter.
Operate only with the proper optical fiber installed in the optical output connectors.
Whenever the optical connectors are empty the device should be turned off.
Before applying power always connect a fiber to the outputs of the device.
Never leave equipment with radiating bare fibers accessible - always cap the connectors.
5. Cleaning of optical connectors
The fiber ends may be damaged if contaminated connectors are inserted. The warranty does not cover some types of
damage, made by the customer. The standard optical connector for optical amplifier is FC/APC.
During the operation each fiber connector may be contaminated by dust or dirt. Even tiny particles of dust will affect the
transmission quality. Dusty fiber optic connector will contaminate other connected optic parts. If optical reception power and
output level of the receiver decrease, active fiber connection should be cleaned and maintained.
Always clean all the fiber optic connectors before setting.
Reel cleaners or prepackaged lint free wipes or swabs with alcohol are the most convenient means of cleaning optical
connectors.
Fiber connectors should never be left uncovered.
Do not exceed the minimum bending radius when connecting cable to the system.
