Data record `std.tia-526-14-d.method.transparent-cord`

Verified 2026-10-25 Confidence: Medium

The TIA foreword of ANSI/TIA-526-14-D (2023) allows a second, sacrificial test cord to spare the reference cord from wear, citing TSB-4979, and notes that it stays modally transparent only when its core and numerical aperture closely match; otherwise the launch drifts from encircled flux.
