TIA Family of Standards


Telecommunication Industry Association (TIA) Engineering Committee TR‑42 develops and maintains voluntary telecommunications cabling infrastructure Standards for user-owned Premises, such as commercial buildings, residential buildings, healthcare and educational facilities, data centers, and industrial buildings. Generic balanced twisted‑pair, optical fiber, and broadband coaxial cabling topologies, design, installation, application support distances, and outlet configurations are addressed in Common Standards. Component Standards detail requirements for cables, connectors, and cable assemblies. TIA TR‑42 Standards also address specifications for laboratory and field testing, intelligent building design, administration, the pathways and spaces supporting the cabling, and telecommunications grounding and bonding. TIA Technical Systems Bulletins (TSBs) provide non-normative guidance on a wide range of telecommunications cabling media and infrastructure‑related subjects.
