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).

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.  This Standard specifies requirements for 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 have been added
  • ANSI/TIA-568-C.0 is referenced for application distance support lengths
