Switches and cable length

My understanding is when a switch is setup in Hub emulation mode you still have full bandwidth and cable length available on each port. Is that correct?

It depends on the implementation by the switch vendor. I know Brocade "quick-loop" provides point-to-point connectivity through the switch to any port configured as a quick-loop port. Cable lengths are the same as in a fabric. The only difference really is that the switch port becomes an "FL" port and provides translation and name server mapping of the FC-AL devices and IDs in the public loop to the fabric devices in the switch.
