SAS uses wide ports composed of (usually, other widths are possible) four 3 gbit links. Each of these has a data rate up to 300 MB/s (not 375, due to 8/10b coding). Thus, a "single" SAS cable carries 1.2GB/s, while a single FC link carries 400 MB/s. SAS links can be up to 8 meters long, although of course this does not compete with the km-long links FC can achieve.
