FOREWORD
Amendment 1 to International Standard ISO/IEC 24702 was prepared by subcommittee 25:
Interconnection of information technology equipment, of ISO/IEC joint technical committee 1:
Information technology.
_______________


6.2.2 Environmental classification
Replace the second paragraph of this subclause by the following new text:
Certain environments (e.g. nuclear, chemical, fire, explosive, damage risk from animals, salt
mist) demand additional requirements beyond those of this clause. Further details on specific
environments are given in ISO/IEC TR 29106.

Table 2 – Details of environmental classification
Replace the row starting with EFT/B (comms) by the following new row:
EFT/B (comms) 500 V 500 V 1 000 V

6.3.3.1 General
Replace the second and third paragraphs including all the bullet points by the following:
This International Standard uses the optical fibre cabling channel Classes of clause 8 of
ISO/IEC 11801 (2002), that is:
• Class OF-300 channels support applications listed in Annex E using cabled all-silica
optical fibres in accordance with 8.4.1 to a minimum of 300 m;
• Class OF-500 channels support applications listed in Annex E using cabled all-silica
optical fibres in accordance with 8.4.1 to a minimum of 500 m;
• Class OF-2000 channels support applications listed in Annex E using cabled all-silica
optical fibres in accordance with 8.4.1 to a minimum of 2 000 m.
In addition, this standard specifies the following Classes for optical fibre cabling channels:
• Class OF-25 channels support applications listed in Annex E using cabled plastic optical
fibre in accordance with 8.4.2 to a minimum of 25 m;
• Class OF-50 channels support applications listed in Annex E using cabled plastic optical
fibre in accordance with 8.4.2 to a minimum of 50 m;
• Class OF-100 channels support applications listed in Annex E using cabled plastic or
plastic clad silica optical fibres in accordance with 8.4.2 and 8.4.3 respectively to a
minimum of 100 m;
• Class OF-200 channels support applications listed in Annex E using cabled plastic or
plastic clad silica optical fibres in accordance with 8.4.2 and 8.4.3 respectively to a
minimum of 200 m;
• Class OF-5000 channels support applications listed in Annex E using cabled all-silica
optical fibres in accordance with 8.4.1 to a minimum of 5 000 m;

• Class OF-10000 channels support applications listed in Annex E using cabled all-silica
optical fibres in accordance with 8.4.1 to a minimum of 10 000 m.
Table 9 Channel attenuation of optical fibre cabling channels
Replace Table 9 by the following new Table 9:

NOTE 1 The modal conditions under which the measurement is made are ffs.
NOTE 2 For singlemode channels the nominal wavelength is 1 310 nm.

7.3.1 General
Replace the two paragraphs of this subclause by the following new paragraphs:
Optical fibre channels shall be comprised of components that comply with Clauses 8, 9 and
10. These clauses specify physical construction (core/cladding diameter and numerical
aperture) and transmission performance. Within the reference implementations of this clause,
the cabled optical fibres used in each cabling channel shall have the same specification.
When more than one physical construction or cabled optical fibre Category is used in a
cabling subsystem the cabling shall be marked to allow each cabling type to be clearly
identified.
