TIA standards documents are developed within the Technical Committees of the TIA and the standards coordinating committees of the TIA standards board. Members of the c

24、ommittees serve voluntarily and without commission. The companies that they represent are not necessarily members of the TIA. The standards developed within the TIA represent a consensus of the broad expertise on the subject. This expertise comes from within the TIA as well as those outside of the T

Users are encouraged to verify that they have the latest revision of the standard. This addendum has been prepared by th

33、2) corresponds to the designations of used within ISO/IEC 11801 or ISO/IEC 24702. Existing Note 1 of table 1 becomes Note 2. ANSI/TIA-568-C.3-1 2 6.4.3 Array Subclause 6.4.3, “Array” shall be modified as follows: 6.4.3 Array 6.4.3.1 General Array system connectivity methods require a specific combin

34、ation of components (array patch cord, optical fiber transitions, duplex patch cord) to maintain polarity. Some of the components are common to other connectivity methods such as duplex systems. NOTES 1 - The array patch cords and array cables of shown in figures 7, 8 and 9through figure 12 are show

35、n unpinned on both ends for simplicity. In some instances, such as when supporting parallel signals, it may be necessary to use a combination of unpinned and pinned connectors on array cables and array patch cords. At any connection using MPO connectors, it is necessary for one plug to be pinned and

36、 the other to be unpinned. 2 - See ANSI/TIA 568 C.0 for guidance on usage of polarity methods. 6.4.3.2 Array patch cords and array cables The Array patch cords and array cables should be clearly identified. 6.4.3.2.1 Type-A:1-1 array patch cord and array cable Type-A:1-1 array patch cords and array
