Reference documentation for fiber label management, address formats, and customer specifications.

How Physical Infrastructure IDs (PIIDs) get assigned to colo rack positions — and how TSmartLabel cross-references Excel fiber assignments against DFSA scope documents to catch gaps.
Customer Label Formats (Meta / Google / Microsoft / Anthropic)
The exact label templates used by each hyperscaler customer — field layout, line order, direction logic, and the common mistakes that make labels unreadable on site.
