IS/IEC 61746 : Part 2 : 2010 Calibration of Optical Time-domain Reflectometers (OTDR) Part 2 OTDR for Multimode Fibres

( Superseding IS/IEC 61746: 2005 )

Reaffirmed 2018

NATIONAL FOREWORD

This Indian Standard (Part 2) which is identical with IEC 61746-2 : 2010 ‘Calibration of optical time-domain reflectometers (OTDR) - Part 2: OTDR for multimode fibres’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the Fibre Optics, Fibres, Cables and Devices Sectional Committee and approval of the Electronics and Information Technology Division Council.

IS/IEC 61746: 2005 has been withdrawn and replaced with IEC 61746 Series. This superseding of Standards is being published to align it with the latest version of IEC 61746 Series.

The text of IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and 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.
