Optical fibre cables - Part 2-20: Indoor cables - Family specification for multi-fibre optical cables
IEC 60794-2-20:2013 is a family specification covering multi-fibre optical cables for indoor use. The requirements of the sectional specification IEC 60794-2 are applicable to cables covered by this standard. Annex B contains a Blank Detail Specification and general guidance in case the cables are intended to be used in installation governed by the MICE table of ISO/IEC 24702 (Industrial premises). This third edition cancels and replaces the second edition published in 2008 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - removal of Annex C; - reference to the most recent fibre standards; - reference to the new series IEC 60794-1-2X. This standard is to be used in conjunction with IEC 60794-1-1, IEC 60794-1-2 and IEC 60794-2. Keywords: family specification covering multi-fibre optical cables for indoor use
