What this source establishes

Cited to show that ordering information fixes a panel’s geometry and leaves its numbering and internal fiber mapping to the assembly document. The per-cassette figures quoted in the guide are arithmetic on the stated chassis counts, not separate claims by the publisher. No product recommendation or performance claim is made.
