Additions To TIA/EIA-568-B.1, B.2, & B.3

  1. TIA/EIA TSB72 centralized optical fiber cabling is incorporated as an alternative to the optical cross-connection located in the telecommunications room when deploying 62.5/125µm and 50/215µm optical fiber cable in the horizontal.

  2. ANSI/ICEA S-90-661-1994 for specifying the physical and mechanical requirements of recognized cables was updated.

  3. The 568SC optical fiber connector axial pull off strength requirement was decreased to 19.4 N (4.4 lbƒ).

  4. Globally, the word “polarization” was replaced with “polarity”.

  5. A provision for common mode terminations for testing connecting hardware was incorporated. This revision accommodates telecommunications networking implementations that may employ common mode terminations in the active equipment.
