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

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

4. Knowledge base

5. CAT 7 (ISO Class F)600 MHz 1.2 GHz in pairs with Siemon connector Full-motion video Teleradiology Government and manufacturing environments Fully 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.GHz

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 tramition over the copper cable is always more practical

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

12. 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
