ANSI/TIA-758-B: Customer-Owned Outside Plant Telecommunications Infrastructure Standard


ANSI/TIA-758-B “Customer-Owned Outside Plant Telecommunications Infrastructure Standard” was developed by the TIA TR‑42.4 Outside Plant Subcommittee and published in March, 2012.

Scope: Customer‑owned outside plant cabling is defined as the cabling installed between buildings or points in a customer‑owned campus environment.  Customer‑owned campus facilities are typically termed “outside plant” (OSP). This Standard specifies requirements for OSP telecommunications pathways and spaces, cable, connecting hardware, and bonding and grounding systems to support a wide range of IT applications (e.g., voice, data, video, alarm, environmental control, security, audio).

Significant changes from the previous edition include:

  • Guidelines for the physical location and protection of below-ground cabling added
  • ANSI/TIA-568-C.0 referenced for application distance support lengths

ANSI/TIA-758-B Content:

  • Cabling Infrastructure
  • Pathways and Spaces
  • Cabling
  • Cabling Enclosures
  • Annexes addressing OSP Symbols and the Physical Location and Protection of Below-Ground Cable Plants
