Interestingly the Fibre Channel Spec includes a 266MBit version, so suspect
somewhere along the line it was deemed a 'standard' . I would also guess the
connector layout and shape of the 'GBIC' was adopted from an existing design
as a de facto, it was only with the true GBIC (1Gbit) that the whole standard
with a proper connector came about.
