Data record std.tia-526-7-a.definition.attenuation

Verified 2026-10-25 Confidence: High

Clause 3.1.2 of ANSI/TIA-526-7-A (2015) treats attenuation and loss as the same quantity: the drop in optical power across the cabling under test, given as a positive decibel figure derived from the ratio of input to output power.
