NATIONAL FOREWORD

This Indian Standard (Part 1/Sec 1) which is identical with IEC 60793- 1-1 (1995) ‘Optical fibres - Part 1: Generic specification - Section 1: General’ including Amendment 1 (1998) issued by the International Electrotechnical Commission (lEC) was adopted by the Bureau of Indian Standards on the recommendation of the Fibre Optics Sectional Committee and approval of the Electronics and Telecommunication Division Council.

This standard applies to primary coated or buffered optical fibres for use in telecommunication equipfnent and in devices employing similar techniques and defines categories of optical fibres as well as packaging.

The text of the IEC has been approved as suitable for publication as Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
