Title Optical fibre cables - Part 2-20: Indoor cables - Family specification for multi-fibre optical distribution cables
Project Number 21539
Abstract/Scope IEC 60794-2-20:2008(E) is part of the IEC 60794 family specification covering multi-fibre optical distribution cables for indoor use. The requirements of the sectional specification IEC 60794-2 are applicable to cables covered by this standard. The main changes from the previous edition include: - cable crushto be measured both during and after load; - cable torsion test length parameter correlated to cable outer diameter; - cable description and construction blank detail specification annexes; - MICE environment blank detail specification is addressed in Annex B.
