EIA/TIA-455-62-B:2003

This part of IEC 60793 establishes uniform requirements for measuring macrobending sensitivity for category B1 to B4 single-mode optical fibres at 1 550 nm and of category A1 multimode fibres at 850 nm and 1 300 nm, thereby assisting in the inspection of fibres and cables for commercial purposes. This standard gives two methods for measuring macrobending sensitivity: - method A: power monitoring - method B: cut-back. Information common to both measurements is contained in clauses 1 to 8.
