21、e optics and is part of the CEN/CENELEC/ETSI (European Telecommunications Standards Institute) cooperation agreement. It complements the Sectional Specification already published as EN 60794-3 (EN 187100). It uses information provided by the ETSI on functional and system related aspects by means of
22、the Interim European Telecommunications Standards (I-ETS): I-ETS 300229: Single-mode optical fibre cables to be used in Optical Aerial Telecommunication Cables, prepared by ETSI/TM1/WG1, reviewed and completed by the CECC.

27、vers Optical Aerial Telecommunication Cables Requirements of the Sectional Specification for Optical Telecommunication Cables are applicable to cables covered by this Standard. The clause 5 of this Standard describes a Blank Detail Specification for Optical Aerial Telecommunication Cables. It incorp
28、orates some minimum requirements common to all European Countries. The clause 6 describes the different options following these minimum requirements accepted as European Standards. The numerical values for these standard options existing in the different european countries have been provided under t
29、heir own responsibility by each National Committee. The future updating and amendment of the table of clause 6 will be done on the same way. Detail Specifications may be prepared based on this Family Specification following in particular requirements of clauses 5 and 6. 2 General The parameters spec
30、ified in this Standard may be affected by measurement uncertainty arising either from measurement errors or calibration errors due to lack of suitable standards. Acceptance criteria shall be interpreted with respect to this consideration. The total uncertainty of measurement for this Standard shall
31、be less than or equal to 0,05 dB for attenuation. The expression of no change in attenuation means that any change in measurement value either positive or negative, within the uncertainty of measurement shall be ignored. The number of fibres tested shall be representative of the cable design and sha
32、ll be agreed between the user and the manufacturer. 3 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
33、dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
