Standards map: who publishes what

A single 100G link touches a dozen documents from six organisations: the IEEE clause that defines the PMD, the SFF document for the module's memory, the OIF agreement for the electrical interface, the ITU-T recommendation for the fibre, the IEC standards for the connector and laser safety, an MSA for the form factor. This page maps the bodies, their document families and numbering, the IEEE 802.3 clauses by PMD, and the question each document answers — so "which spec says so?" has a quick answer.

In CodingBox

CodingBox implements the SFF-8472, SFF-8636, SFF-8024, CMIS and INF-8077i documents for reading and editing memory, and names the IEEE/FC/IB codes it decodes from the compliance bytes — the specifications section holds the byte-level detail (MSA & standards, Spec revisions).
