a. The link data rate does not represent the actual performance of the link. The actual
performance depends on many factors that include latency through the adapters, cable
lengths, and the type of workload.
b. Where applicable, the minimum fiber bandwidth distance in MHz-km for multi-mode fiber optic
links is included in parentheses.
