"Hazard level" refers to the potential hazard from laser emission at
any location in an end-to-end optical fiber communication system that
may be accessible during service or in the event of a failure. The
assignment of hazard level uses the AELs for the classes.
Hazard levels for optical transmission equipment are assigned in either
of the following two ways:
•
the actual output power from the connector or fiber cut.
•
if automatic power reduction is used, the output power at the
connector or fiber cut at one second after automatic power
reduction takes place, provided that maximum output and restart
conditions are met.
Optical telecommunication equipment is generally classified as IEC
Class 1 or FDA/CDRH Class I, because under normal operating
conditions the transmitter ports terminate on optical fiber connectors.
These are covered by a front panel to ensure protection against
emissions from any energized, unterminated transmitter.
The circuit packs themselves, however, may be IEC Class 1 or 3A or
FDA/CDRH Class I or IIIb.
