Fibre Channel transmission speed

hi FC experts

i am reading the Wikipedia article of Fibre Channel and got a bit confused about the transmission rates of FC described in the article.

Fibre Channel
http://en.wikipedia.org/wiki/Fibre_Channel

in the table of Fibre Channel Speed Variants, the Line-Rates are from 1.0625 to 21.04 Gbaud (eq. Gbps??) while the throughput is from 200 to 5,100 MBps (Mbps??).

in the table of Optical Carrier Medium Variants, the speeds are from 100 to 400 MByte/s (eg. 1/8 Mbps??) for single-mode fibre and multi-mode fibre with varied Transmitters.

so basically... how fast is FC?  Gbps level or Mbps level?

does Line-Rate of FC mean the *internal* transmission speed of a FC switch, while Medium-Seed for the *external* speed between switches?? the bottleneck is here?

many thanks in advance.

regards,
bbao
