23、ng fiber optic cables for outdoor use intelecommunications applications.The first edition of this Standard was approved by ICEA on March 4, 1992, and the secondrevision on September 15, 1999. A third revision was approved by ICEA on June 8, 2005.It was published by ICEA, but was not published as an
24、ANSI approved Standard. Thisrevision to the Standard was approved by ICEA on September 13, 2006. This Standardwas approved by The American National Standards Institute (ANSI) on December 8,2006. This Standard was adopted by the Telecommunications Industry Association(TIA) as TIA-472D000-B in April 2
