22、C/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 the Interim European Telecommunication
23、s Standards (I-ETS): I-ETS 300226: Single-mode optical fibre cables to be used in duct and for directly buried application, prepared by ETSI/TIM1/WG1, reviewed and completed by the CECC.

Requirements of the Sectional Specification for Optical Telecommunication Cables a
29、re applicable to cables covered by this Standard. The clause 5 of this Standard describes a Blank Detail Specification for Optical Telecommunication Cables to be used in ducts or direct buried application. It incorporates some minimum requirements common to all European Countries. The clause 6 descr
30、ibes 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 their own responsibility by each National Committee. The future updating and amendment
31、 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 specified in this Standard may be affected by measurement uncertainty arising either from
32、 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 be less than or equal to 0,05 dB for attenuation. The expression of no change in atte
33、nuation 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 shall be agreed between the user and the manufacturer. 3 Normative references This Europ

These normative references are cited at the appropriate places in the text and the publications are listed hereafter.
