Adapter FRU number
00WT111 (Designed to comply with RoHS requirement)
I/O bus architecture
PCIe2.0 x8
Slot requirement
For details about slot priorities, maximums, and placement rules, see PCIe adapter placement rules
and slot priorities (http://www.ibm.com/support/knowledgecenter/POWER9/p9eab/
p9eab_mtm_pciplacement.htm) and select the system you are working on.
FC compatibility
2, 4, 8 Gigabit
Cables
Cables are the responsibility of the customer.
Use multimode fiber optic cables with shortwave lasers that adhere to the following specifications:
• OM3: Multimode 50/125 micron fiber, 2000 MHz x km bandwidth
• OM2: Multimode 50/125 micron fiber, 500 MHz x km bandwidth
• 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 cable, the characteristics of the OM2 cable apply to the entire length of the cables. The
following table shows the supported distances for the different fiber optic cable types at different link
speeds.
