High Speed Confusion........I am a mechanical engineer working in the field of electrical interconnections (connectors). Can someone explain in basic terms what the frequecny of operation the following "protocols" run at:

CAT 5
100 Base T Ethernet
1000 Base T Ethernet
IEEE 1394
Mil-Std-1553
Fiber Channel

Any comments are welocme. Thank you in adavcnce.

Cat 5 is the cable spec for fast ethernet (100BaseT) The 5 means the twisted pairs are twisted 5 times per foot.

100 Base T is fast ethernet, transmitted over Twisted pair cable. It has a raw data rate of 100 Mbits/s and is full duplex

1000 Base T is Gigabit ethernet, over twisted pairs, raw data rate of 1000 Mbits/s and is full duplex

IEEE 1394 is firewire. raw data rate is 400/Mbit/s and up.

Mil-std-1553 is a command/response bus transmitted over a single twisted shielded pair. 1553 is very robust, with emissions controlled to met aircraft EMC requirements. Raw data rate is 1Mbit/s and is half duplex

Fiber Channel is a protocal that can be implemented over either copper wire or fiber. It has variable data rates starting at about 100Mbits/s and going to well above 1000Mbits/s.
