Paris, April 17, 2002 � By March 22nd, the Connector committee SC488 within the International Electrotechnical Commission (IEC) had to finally vote on the connector proposal from Nexans GG45. The committee voted 100% positive and the standard IEC 60603-7-7 will be published within the next 3 months.
IEC 60603-7-7: Connectors for use in D.C. Low Frequency analogue and in digital high speed data applications: Part 7-7: 8 way connectors for frequencies up to 600 MHz (Category 7 Detail Specification).
�We are impressed with the broad international support and appreciates the unanimous approval from all countries. We believe this is indisputable support of its vision of "next generation cabling� said Pascal Portevin President of Nexans� Telecom Division.
In August last year the standardization committee for building communication cabling, ISO SC25/WG3, has already chosen GG45 as the interface for Class F cabling systems to ensure backwards compatibility for the high end class of data communication infrastructures.
IEC 60603-7-7 defines a backwards-compatible 600 MHz connector which supports a new high speed interface for Cat. 7 transmission as well as the traditional interface RJ45 for lower speed applications. Besides the 2 transmission paths, the connector contains a switch mechanism, which is activated by a corresponding plug. Backwards compatibility enables enterprises to install today a new 600 MHz infrastructure that is also compatible with the widely used current classes of RJ45 connectors in existing PC's and data-switches.
Since the standard has been finally settled now, end-users who invest into backwards-compatible Cat. 7 connectivity are secured to get a non-proprietary solution with guaranteed interoperable plugs and connectors from multiple vendors.
IEC 60603-7-7 has to be viewed together with a second standard which also describes the 600 MHz interface but in a non backwards compatible form. The split of the documents was made to reach a clear structure: IEC 60603-7-7 describes switched and backwards compatible products. IEC 61076-3-110 describes the non switched products. Both standards use the identical interface definition for 600 MHz. IEC PAS61076-3-110 is already publicly available.
