1000baseSX cards can only operate at 1000Mbps, full duplex. The same was true
for 10baseFL and 100baseFX fibre adapters.

>From Intel's website:
  The Intel® PRO/1000 F Gigabit Server Adapter uses the 82543GC Ethernet
  controller chip labeled with an Intel® brand, SC fiber-based, 62.5/125um or
  50/125um multimode, supports 32/64 bit at 33/66 MHz, and runs at 1000 Mbps.
  It must run in full duplex mode.

  The Intel® PRO/1000 XF Server Adapter uses the 82544 controller, fiber based
  as above and adds PCI-X support. End of Year 2001

Richard Tector
