Cables
For information about the cables, see "Cables."
Attributes provided
v NPIV capability is supported through VIOS.
v Requires a PCI Express generation-2 x8 slot for all four ports to operate at full speed.
Cables
Use multimode fiber optic cables with shortwave lasers that adhere to the following specifications:
v OM3: Multimode 50/125 micron fiber, 2000 MHz x km bandwidth
v OM2: Multimode 50/125 micron fiber, 500 MHz x km bandwidth
v OM1: Multimode 62.5/125 micron fiber, 200 MHz x km bandwidth
Because core sizes are different, OM1 cables can only be connected to other OM1 cables. For best results,
OM2 cables should not be connected to OM3 cables. However, if an OM2 cable is connected to an OM3
