TB003 - Labelling of Optical Fibre Panels and Enclosures

Text in Italics is reproduced with permission from AS/CA S009.

Applicability

The following applies only to telecommunication cabling installations in Australia and New Zealand seeking conformance of optical fibre labelling to the Wiring Rules - AS/CA S009:2013.

Summary

It is mandatory to meet the labelling requirements for optical panels and enclosures in Australia as part of the cabling Wiring Rules AS/CA S009.  It is also a requirement in New Zealand when AS/CA S009 is specified in project documentation.  Labelling is a requirement placed on the registered cabler under AS/CA S009 because the positioning of the labels must be done at time of cabling installation.

There are two types of labels that shall be applied to optical fibre panels and enclosures:-

·          A Warning Label – a triangular label containing the ‘star-burst’ laser symbol

·          An Explanatory Label – a rectangular label stating the hazard and the caution

The location of the labels shall be:-

·          A Warning Label on each fibre patch panel, even if it is inside an enclosure, and

·          An Explanation Label on the front of a closed enclosure door and another Explanation Label clearly visible when front viewing after the door is opened.

 Conformance requirements

The Cabling Provider Rules require compliance with AS/CA S009, which sets out the requirements for labelling of optical fibre panels and enclosures.

The conformance requirements of AS/CA S009:2013 for labelling of optical fibre panels and enclosures, are based on the requirements of AS/NZS IEC 60825.1:2011 for label sizes and AS/CA S008:2010 for label durability.

All optical fibre panels and enclosures shall be labelled with warning markings to warn of the potential that hazardous laser levels may be present.

The laser warning marking shall consist of:-

(a)    a Warning Label meeting the requirements of Figure 1 of AS/NZS IEC 60825:2011; and

(b)    an Explanatory Label meeting the requirements of Figure 2 of AS/NZS IEC 60825.1:2011.

 Labelling of optical fibre panels and enclosures

AS/CA S009:2013 Clause Numbers are shown here.

 11.1.6.1   Warning of potential hazardous laser levels

All optical fibre panels and enclosures shall be labelled to warn of the potential that hazardous laser levels may be present.

11.1.6.2 Access to emitted radiation

Each optical connector, splice box or other part emitting radiation when opened shall be marked, e.g. with a label, sleeve, tag or tape.

Note: The labelling for connectors may be located in close proximity where mounting the label on the connector itself is not practical.

11.1.6.3 Types of warning markings

The warning marking shall consist of—

(a) a Warning Label meeting the requirements of Fig 1 of AS/NZS IEC 60825.1; and

(b) an Explanatory Label meeting the requirements of Fig 2 of AS/NZS IEC 60825.1.

11.1.6.4 Laser warning marking style

Markings shall be coloured black on a yellow background appropriately sized and legible for the area served. 

11.1.6.5 Laser explanatory label wording

The Laser Explanatory label shall provide the viewer with warning of potentially dangerous laser radiation.  Wording on the label should be such that effective warning is given to any person that may not be familiar with laser radiation and its danger to exposure.  Laser beams heve the ability to damage eyesight.

The text for the Explanatory Label should be as follows:

CAUTION – HAZARD

POTENTIAL VISIBLE AND INVISIBLE LASER RADIATION

DO NOT STARE INTO THE BEAM OR VIEW DIRECTLY

WITH NON-ATTENUATING OPTICAL INSTRUMENT

 

The above wording for the Laser Explanation Label is not mandatory and other words that contain the same meaning may be used.

11.1.6.6 Marking durability

The durability of the marking shall meet Clause 5.3.3.3 of AS/CA S008:2010.

 11.1.6.7  Fibre outlets in work areas

Fibre outlets in work areas do not require Explanatory Label markings.

 11.1.6.8 Marking of groups of connectors, outlets and access points

Groups of connectors, outlets or access points such as patch panels may be marked as a group.  A single clearly visible triangular Laser Warning Label marking may be used rather than having one Laser Warning Label for each connector/outlet.  A minimum of one Laser Explanatory Label shall be installed on the rack or frame for each location.

 11.1.6.9 Multiple markings

Where a group of connectors/outlets are enclosed within a housing then an Laser Explanatory Label shall be clearly visible both before and after the housing is opened.  This may require the use of more than one marking, such as one on the outside of a cabinet door and one inside on the rack/frame.
