620004-0 Rev. E
IEC/EN 60825-2: Safe Use of Optical Fiber Communication Systems
ing to IEC 825-1. However, the power output level of the LGCell system is so low
that it always falls into the class 1 hazard level even under 100% modulation condi-
tions. The absolute maximum allowed at 1300nm is +9.5 dBm. The absolute maxi-
mum accessible output of the LGCell fiber optic system is –11.5 dBm. Therefore
there is no restriction as to location of use of the LGCell system and there is no label-
ing requirement.
B.3.5 Suggested Work Practices
The LGCell is covered under these parts of section D7 of 60825
The following working practices are suggested for working on the LGCell system:
• Viewing Fiber: Do not stare with unprotected eyes at the connector ends of the
fibers or the ports of the hub.
• Test Fibers Cables: When using test fiber optical cables, the optical power source
shall be the last to be connected and the first to be disconnected.
• Fiber ends: Any unconnected fiber ends should be covered with an approved cap.
Do not use tape.
• Broken Fiber Cables: Do not stare with unprotected eyes at any broken ends of
the fibers. Report and have any broken fiber cables replaced.
• Cleaning: Use only approved methods for cleaning optical fiber connectors.
• Modification: Do not make any unauthorized modifications to this fiber optical
system of associated equipment.
• Live work: Live work is permitted on the LGCell as it is a class 1 hazard.
• Signs: No warning signs are required.
• Test Equipment: Use class 1 test equipment.
