17 Structured Cabling History How did it start?. 1976: Invention of Ethernet Xerox PARC: Robert Metcalfe & David Boggs Ethernet: Distributed Packet Switching For Local Computer Networks ALOHA based: uses CSMA/CD, developed in the 60s. 1980: IEEE publishes the first draft of Ethernet 1982: The Ethernet Blue Book Xerox PARC 10Mb/s 1985: First IEEE standard Based on The Ethernet Blue Book Shared bus topology 1980s: AT&T implements 1Mb/s Ethernet on twisted pair. No Cable category yet. 100m limit established. 8P8C connector

20 Structured Cabling History First the IEEE designs an application. (in collaboration with the TIA and ISO) Then the TIA and ISO can offer a cabling system for it. Not the opposite!

30 40G over Copper Does NOT exist yet Future Solutions So the following solutions do NOT accept 40G: Category 6 A Category 7 Category 7 A

31 Future 40G Base-T Future Solutions IEEE NG Base-T study group formed and is studying 40Gbase-T at 2GHz TIA/EIA TR42.7 has started working on a specification of a future Category 8 solution ISO PDTF study group is evaluating options for Class I and Class II.

32 Future 40G Base-T Future Solutions The TIA/EIA Category 8: First sample F/UTP system proved functional. Most solutions will be F/UTP, but U/UTP is possible if and when the technology allows it. Most likely the usual 8P8C (RJ45) connector. 2-connector channel only! Permanent link 24m only!!! Patch cords 4 to 8m depending on resistance.

33 Future 40G Base-T Future Solutions The ISO Class I: Based on Category 8.1 components. This is equivalent to TIA Category 8. The ISO Class II The ISO Class II: Based on Category 8.2 components. S/FTP cable similar to Categoy7 A, but improved to 2GHz. Non-RJ45 connectors similar to those from Category 7 A. Providing improved performance

35 Standards Evolve Conclusion As technology advances, the standards change to adapt. This is always a work in progress. Choosing the right cabling system must include an analysis of the current and future needs. But it is the application that determines the cabling, not the opposite.
