The carrier frequency for 10b2 is 10Mhz.

It's not a modulated signal encoding. There's no modulation, and so there's no carrier.

The bandwidth is probably 20MHz, due to the Manchester encoding.

It is Manchester encoding on a 10MHz clock signal. Perhaps carrier isn't quite the right word.

I take back by correction. Thanks, and sorry. Manchester encoding really is a form of phase modulation (BPSK). It makes sense to think of it as a 10MHz baseband signal modulated by a 10MHz carrier, and therefore having a 20Mhz bandwidth.
