(Amendment)Safety of laser products -- Part 2: Safety of optical fibre communication systems (OFCS)
Safety of laser products -- Part 2: Safety of optical fibre communication systems (OFCS)
Provides requirements and specific guidance for the safe operation and maintenance of optical fibre communication systems (OFCS). In these systems optical power may be accessible outside the confinements of transmitting equipment or at great distance from the optical source. This standard requires the assessment of hazard levels at accessible locations as a replacement for classification according to IEC 60825-1. It applies to the complete installed end-to-end OFCS, including its components and subassemblies that generate or amplify optical radiation. Individual components and subassemblies that are sold only to OEM vendors for incorporation into a complete installed end-to-end OFCS need not be assessed to this standard, since the final OFCS should itself be assessed according to this standard. The objective of this Part 2 of IEC 60825 is: to protect people from optical radiation resulting from OFCS; - provide requirements for manufacturers, installation organizations, service organizations and operating organizations in order to establish procedures and supply information so that proper precautions can be adopted; - ensure adequate warnings are provided to individuals regarding the potential hazards associated with OFCS through the use of signs, labels and instructions.

Varnost laserskih izdelkov - 2. del: Varnost komunikacijskih sistemov z optičnimi vlakni (OFCS) (IEC 60825-2:2004/A1:2006)
Ta 2. del IEC 60825 podaja zahteve in posebna navodila za varno obratovanje in vzdrževanje komunikacijskih sistemov z optičnimi vlakni (OFCS). V teh sistemih je optična moč lahko dostopna izven omejitev opreme za prenos ali na veliki razdalji od optičnega vira. Ta standard zahteva oceno stopenj nevarnosti na dostopnih lokacijah kot nadomestilo za razvrstitev v skladu z IEC 60825-1. Velja za celotne nameščene OFCS med dvema točkama, vključno z njihovimi sestavnimi deli in podsklopi, ki generirajo ali ojačajo optično sevanje. Ni treba, da so posamezni sestavni deli in podsklopi, ki se prodajajo samo prodajalcem-proizvajalcem originalne opreme (OEM) za vgradnjo v kompletne nameščene OFCS med dvema točkama, ocenjeni po tem standardu, saj mora biti sam končni OFCS ocenjen v skladu s tem standardom. Namen tega 2. dela IEC 60825 je: - zaščititi ljudi pred optičnim sevanjem, ki ga povzroča OFCS; - zagotoviti zahteve za proizvajalce, organizacije, ki nameščajo, servisne organizacije in organizacije za obratovanje, z namenom vzpostaviti postopke in zagotoviti podatke, da bi lahko bili zagotovljeni ustrezni varnostni ukrepi; - zagotoviti, da so posameznikom zagotovljena ustrezna opozorila glede morebitnih nevarnosti, povezanih z OFCS, z uporabo znakov, oznak in navodil.

4.4 Cable connectors
Replace the existing text of Subclauses 4.4.1, 4.4.2 and 4.4.3 as follows.
4.4.1 Unrestricted locations
In unrestricted locations, if the accessible radiation level exceeds:
– hazard level 2 within the wavelength range 400 nm to 700 nm, or
– hazard level 1 in all other cases,
then suitable means shall limit access to the radiation from the connector.
NOTE In an unrestricted location the highest hazard levels permitted are hazard level 2M for the wavelength
range 400 nm to 700 nm and hazard level 1M in all other cases (see 4.9.1)
---------------------- Page: 5 ----------------------
60825-2 Amend. 1 © IEC:2006 – 5 –
4.4.2 Restricted locations
In restricted locations, if the accessible radiation level exceeds:
– hazard level 2M within the wavelength range 400 nm to 700 nm, or
– hazard level 1M in all other cases,
then suitable means shall limit access to the radiation from the connector.
NOTE In a restricted location the highest hazard level permitted is hazard level 1M, 2M or 3R, whichever is the
higher (see 4.9.2).
4.4.3 Controlled locations
In controlled locations, if the accessible radiation level exceeds:
– hazard level 2M within the wavelength range 400 nm to 700 nm, or
– hazard level 1M in all other cases,
then suitable means shall limit access to the radiation from the connector.
NOTE In a controlled location the highest hazard level permitted is hazard level 3B (see 4.9.3).

4.6 Labelling or marking
Replace the existing text of Subclause 4.6 by the following.
4.6.1 General requirements
Where required by this subclause, each optical connector, splice box or other part emitting
radiation when opened shall be marked (e.g. with a label, sleeve, tag, tape etc.), if the hazard
level at the location is in excess of hazard level 1. The information shall consist of the
information identified in Tables 1, 2 or 3 as applicable.
Where the accessible radiation at points of disconnection is hazard level 1 or hazard level 1M
it is permitted for the above information to be provided in information for the user instead of
as a marking on the product.
Markings shall be coloured black on a yellow background. Labels reproduced in the
documentation provided by the manufacturer or by the operating organisation are permitted to
use black on a white background.
It is acceptable to reduce the marking in size, providing that the result is legible. For
subassemblies containing lasers or optical amplifiers, it is the responsibility of the
manufacturer of the subassembly to provide such labelling; all other labelling is the
responsibility of the operating organization.
Except as permitted below, each optical connector, splice box or other part that is intended to
permit access to optical radiation when opened shall be marked (e.g. with a label, sleeve, tag,
tape etc.) in accordance with Tables 1, 2 or 3, as applicable.
---------------------- Page: 6 ----------------------
60825-2 Amend. 1 © IEC:2006 – 7 –
In addition to the marking required in this Part 2, certain subassemblies may also need to be
marked because of their stand-alone application under Part 1, and in such situations it is left
to the manufacturer of the OFCS whether they supplement the marking required by Part 1 or
replace it with the marking as required by Part 2.

Conditions applicable to the above table:
a
Subclause 4.4.1 requires access to radiation from a connector to be limited to hazard level 1 by a
suitable means and the mechanical design of the fibre cables must be consistent with the relevant
standard within the IEC 60794 series (see 4.3). Therefore, hazard level 1M is exempt from marking
requirements.
b
Hazard symbol warning label according to IEC 60825-1, Figure 14.
c
Where the source of the radiation is a light emitting diode, the word “Laser” above shall be replaced by
“LED”.
d
Replacing the word “Radiation” with “Light” for radiation in the range 400 nm to 700 nm is optional.
e
Explanatory label (outline) according to IEC 60825-1, Figure 15. It is permitted for this outline to also
