Laser Safety Information and Guidelines
The FSP 3000 C equipment uses lasers as fiber-optic transmitter sources. These lasers
are inherently safe unless mishandled. The equipment meets the specifications for a
hazard level 1M product and a Class 1M Laser product, even if a fiber-optic transmitter is
switched to “Forced On” during installation or testing operations (21 CFR 1040.10 and
1040.11, IEC 60825-1:2014 Ed. 3.0, and IEC 60825-2:2004+A1:2006+A2:2010
compliant). To switch a laser or transmitter to “Forced On” means that the laser or
transmitter is set to forced on mode.
The product is characterized by the fact that
l Under normal operating conditions, no human access to hazardous laser radiation is
possible because the equipment operates as a closed system;
l During operation, laser aperture terminations feed into fiber connector receptacles
comprising a removable protective plug; and
l All laser circuit packs operate in a controlled environment.
The accessible laser radiation at the connectors that can be opened by an end user is not
hazardous for the naked eye (hazard level 1M), provided that the laser safety
mechanisms are activated and no optical instruments are used, which may focus the
laser beam.
In compliance with Class 1M laser safety requirements, the lasers of some traffic
modules are controlled by an Automatic Laser Shutdown (ALS) mechanism and
Automatic Restart Procedure (ARP). The ALS mechanism reduces the optical output
power of the network transmitters in the event of a broken network fiber or an opened
connector. The ARP causes the laser to automatically restart once the disruption has
been corrected.
