Standards map: ITU-T, IEC, TIA/ISO, Telcordia, IEEE, national

Every number in this category — 0.35 dB/km, 9.2 µm, 0.75 dB per connector pair, Class 1M, −35 dB reflectance — comes from a standard, and a tender, an acceptance test or a dispute is settled by citing the right one. The bodies overlap: ITU-T defines the fibre, IEC defines how to test it and the cables and connectors around it, TIA and ISO/IEC define structured cabling, Telcordia defines what North American carriers buy, IEEE and ITU-T define the systems that light the fibre, and national bodies adopt or add to all of that. This page maps the documents by body and by task.

In CodingBox

A module's compliance codes point straight into this map: the IEEE 802.3 clause of its PMD, the ITU-T application code of a WDM module, the MSA that defines its memory map. CodingBox decodes those bytes into names, so the datasheet, the standard and the plant specification can be read against each other (Compliance codes, Standards map of optics).
