Trasmition of 40GBase-T and 100Gbase-T over category 7A copper cables Steven Fratello
Need • Copper wires are only useful for short distance transmitions • Alien talk often disrupts the signal on a copper cable • Fext • Next
Need www.cisco.com/en/US/products/hw/optical/ps201... Increase in network traffic 1996-2001
Need • The copper cable determines the distance before the signal becomes to weak and distorted to be recoverable • This distance determines the amount of repeaters used along the wire
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. www.nexans.us/eservice/US-en_US/navigatepub_1...
Knowledge base • Gbase-t- gigabits per second on a copper wire http://www.pmi.it/file/contenuti/003853/img_01.jpg
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
Kavehrad 07 • it is possible to extend the length of category 7 copper cables from 70 meters to 100 meters (Kavehrad 07)
I. Kalet and S. Shamai • Present copper wire systems operate far below theoretical capacity
Viterbri decoder • “1.Branch metric calculation • 2.Path metric calculation • 3.Traceback • Encoded stream > branch metric calculation> path metric calculation> Traceback> decoded stream
Purpose • To Determine the distances which 100Gbase- T is more practical than 40Gbase-T.
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
Do Ability • Very doable • Most info can be recorded on a computer • Only the copper cables are needed
Protocols • Data is sent from one computer to another • Computer receiving the data would record how much Giga bites is received. • Data will be run through the viterbri decoder
Budget • Vendor Object Price • Nexans Category 7A copper $19.55 • cable 200 meters • Science res computer
Methodology • Category 7A cables • 40GBase-T run through 100GBase-T • Copper cable run through copper cable • Internet signal sent over cable Signal strength recorded on receiving computer Data run through Viterbri decoder Data statistically analyzed on spss
