Please log in for more thread options Hello - ----------------------------------------------------------------------------------- A. What would be total number of Symbols that can be Received in 1 sec , for 100Mbs, 1000Mbps PHY? Would this depend on the media whether it is Copper of Fiber ? My understanding is that it would depend on the media, as the Encoding/Decoding schemes are different- for 1000B-T which uses 4PAM-5 , and 1000B-X uses 8B/10B. Could the experts please comment on the above ? As per my calculation for 1000BASE-X Fiber media which uses 8B/10B encoding 1. For every 8 bits of data 10 symbols are used , so in 1 sec for 1000Mbps it would Receive 1250MSymbols. Is this number right ? 2. For 1000BASE-T what would the total number of symbols that can be Received in 1Sec? I would appreciate corrections/comments on the above or any pointers . Thanks Kott | ||||||||||||||||

Sounds very much like homework. Most USENET groups frown on dong student's homework. > Hello -
