| Title | Optical fibres - Part 2-50: Product specifications - Sectional specification for class B single-mode fibres |
| Project Number | 23750 |
| Abstract/Scope | IEC 60793-2-50:2012 is applicable to optical fibre categories B1.1, B1.2, B1.3, B2, B4, B5 and B6. A map illustrating the connection of IEC designations to ITU-T designations is shown in Annex I. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables. This fourth edition cancels and replaces the third edition, published in 2008, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - aligns the requirements with the relevant ITU-T Recommendations; - adds another option to the list of alternative primary coating diameter constructions in Table 2 and subsequent family specifications; - related modification of coating strip force in Tables 4 and 11; - removes the jumper cut-off wavelength in Table 5; - modifies B6 sub-categories; aligns B6-b MFD on B1.3 MFD. Keywords: information transmission equipment and optical fibre cables |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
