  1. Trasmition of 40GBase-T and 100Gbase-T over category 7A copper cables Steven Fratello

  2. Need • Copper wires are only useful for short distance transmitions • Alien talk often disrupts the signal on a copper cable • Fext • Next

  3. Need www.cisco.com/en/US/products/hw/optical/ps201... Increase in network traffic 1996-2001

  4. Knowledge base

  5. Knowledge base CAT 7(ISO Class F)600 MHz1.2 GHz in pairs with Siemon connector Full-motion videoTeleradiologyGovernment and manufacturing environmentsFully Shielded (S/FTP) system using non-RJ45 connectors but backwards compatible with hybrid cords.Until February 2008, the only standard (published in 2002) to support 10GBASE-T for a full 100m.

  6. Kavehrad 07 • it is possible to extend the length of category 7 copper cables from 70 meters to 100 meters (Kavehrad 07)

  7. Enteshari/Kavhrad 09 Tranmition at 40Gbase-T is practical at lengths up to 50 meters Transmition at 100GBase-T can be practical at lengths up to 10 meters

  8. Viterbri decoder • “1.Branch metric calculation – calculation of a distance between the input pair of bits and the • four possible “ideal” pairs (“00”, “01”, “10”, “11”). • 2.Path metric calculation – for every encoder state, calculate a metric for the survivor path • ending in this state (a survivor path is a path with the minimum metric). • 3.Traceback – this step is necessary for hardware implementations that don't store full • information about the survivor paths, but store only one bit decision every time when one • survivor path is selected from the two.” • Encoded stream > branch metric calculation> path metric calculation> Traceback> decoded stream

  9. Purpose • To Determine the distances which 100Gbase- T is more practical than 40Gbase-T.

  10. Hypothesis Alternate hypothesis- The 100Gbase over the copper cable will be more practical than the cable transporting 40Gbase in short distances Null Hypothesis- The 40Gbase transmition over the copper cable is always more practical

  11. Do Ability • Very doable • Most info can be recorded on a computer • Only the copper cables are needed

  12. Protocols • Data is sent from one computer to another • Computer receiving the data would record how much data is received • Data will be run through the viterbri decoder

  13. Budget • Vendor Object Price • Nexans Category 7A copper $19.55 • cable 200 meters

  14. Methodology • Category 7A cables • 40GBase- run through 100GBase-T • Copper cable run through copper cable Signal strength recorded on receiving computer Data run through Viterbri decoder Data statistically analyzed on spss
