have received adequate training in laser safety and servicing of the system
involved. Examples include optical cable ducts and switching centers.
• 3.14 Location with Restricted Access: A location where access to the protective
housing is restricted and not open to the public. Examples include industrial and
commercial premises, PBX rooms, computer system rooms, and optical test sets.
Distributed fiber networks may pass through unrestricted public areas, restricted
areas within premises, as well as controlled areas or they may be deployed entirely
within restricted business premises.
• 3.18 Optical Fiber Communication System: An engineered assembly for the
generation, transference, and reception of optical radiation arising from lasers in
which the transference is by means of optical fiber for communication purposes.
• 3.19 Reasonable Foreseeable Event: An event, the occurrence of which under
given circumstances can be predicted fairly accurately, and the occurrence of
which is a possibility. Examples of reasonably foreseeable events might include
the following: fiber cable break, optical connector disconnection, operator error or
inattention to safe working practices. Reckless use or use for completely inappro-
priate purposes is not to be considered as a reasonably foreseeable event.
B.3.3 Installation Notes
The LGCell is covered under these parts of section 5 of 60825:
• 5.2.1.3 Test Equipment: During installation or testing of an optical fiber cable or
system, only test equipment of laser Class 1 should be used.
• 5.2.1.5 Installation Rules: Each person engaged in the installation or service of an
optical fiber cable communication system should observe all rules, procedures, and
practices established for the safe operation of optical fiber communication sys-
tems.
B.3.4 Evaluation of LGC System
The LGCell is covered under Annex A of 60825.
The LGCell system is a self-contained product that contains an optical fiber commu-
nication system that would be safe under normal operating conditions because the
optical radiation is totally enclosed and contained under intended operation. How-
ever, because of the extended nature of the system, the optical power may be accessi-
ble a kilometer from the optical source. The LGCell system contains LEDs, which are
the source of radiation covered under IEC 825. Usually a whole fiber optical commu-
nication system would not be classified under IEC 825-2 in the same way required
under IEC 825-1. This is because, under intended operation, the optical power is
totally enclosed, and it could be argued that an interpretation of IEC 825-1 would
give a class 1 to all systems, which may not accurately reflect the hazard potential of
some systems. If the emitter can be operated separately, it should be classified accord-
