: Recognition of new connectivity and media types, such as Single-Pair Ethernet (SPE) for IoT sensors and security.

Perhaps the most significant technical shift in TIA-942-C is the recommendation for optical cabling media. tia-942-c pdf

| Area | Change in Rev C | |------|----------------| | | Introduces “MDA” (Main Distribution Area), “IDA” (Intermediate Distribution Area), “HDA” (Horizontal Distribution Area), “ZDA” (Zone Distribution Area) – reorganized from earlier labels. | | Redundancy levels | Clarifies “Tier” definitions (I, II, III, IV) and adds guidance for “Concurrent Maintainability” and “Fault Tolerance” . | | Cabling | Supports Category 8 copper (25/40GBASE-T) and OM5 fiber (wideband multimode). | | Hybrid data centers | Adds sections for edge data centers , modular data centers , and multi‑tenant environments. | | Environmental conditions | Updates temperature/humidity ranges to match ASHRAE Class A1–A4 (allowing up to 27°C dry bulb in some classes). | | Power & cooling | More specific references to rack‑level power monitoring , cooling modes (air, liquid), and containment (hot/cold aisles). | | Security | Adds physical security layers (man‑traps, biometrics, surveillance) mapped to tier levels. | | Testing | New annex on testing protocols for copper/fiber links (including MPO/MTP assemblies). | : Recognition of new connectivity and media types,
