To compute number of Good symbols

Sep 22, 2006 2 Replies

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 ?


  1. 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.
