TIA/EIA/IS-729 ?Technical Specifications for 100 Ohm Screened
Twisted-Pair Cabling
These are the addendums added since the original publication
of the now obsolete ANSI/TIA/EIA 568-A in 1995.
These documents do not include parameters for the specification
of 250MHz Category 6. This is addressed in ANSI/TIA/EIA
568-B.2.1 as an addendum due for publication in July 2002.
The B Series takes precedence over the technical contents
of the aforementioned bulletins, addenda and interim standard.
All definitions have been harmonized across all telecommunications
infrastructure standards. We now have performance specifications
provided for Category 5e balanced 100 Ohm cabling, not exclusive
to UTP. Added are performance specifications provided for
50/125 mm optical fiber and cables. Alternate fiber connector
designs are allowed in addition to the 568SC, this is with
reference to the new Small Form Factor Connectors.
One of the many critical changes from the previous ANSI/TIA/EIA
568-A and its five addendums, is the dropping of the basic
link in favor of the permanent link.
