- ^ a b Transfer speed = lanes × bits per hertz × spectral bandwidth
- ^ a b Effective bits per hertz per lane after loss to encoding overhead.
- ^ a b The spectral bandwidth is the maximum rate at which the signal will complete one hertz cycle. It is typical half the symbol rate, because one can send a symbol both at the positive and negative peak of the cycle. Exceptions are 10BASE-T where it is equal because it uses Manchester code, and 100BASE-TX where it is one quarter because it uses MLT-3 encoding.
- ^ a b At shorter cable length, it is possible to use cables of a lower grade than that is required for 100 m. For example it is possible to use 10GBASE-T on a Cat 6 cable of 55 m or less. Likewise 5GBASE-T is expected to work with Cat 5e in most use cases.
