Data record `std.tia-526-14-d.method.otdr-bidirectional`

Verified 2026-10-25 Confidence: Medium

Clause G.6 of ANSI/TIA-526-14-D (2023) defines bidirectional OTDR attenuation as the mean of the two directions, keeping both cords connected between the two runs so identical fiber pairs meet each time, and warns that reflectance must not be averaged because it depends on direction; no averaging is defined for source and meter results.
