Specification Description
Link cost The sum of all established/low metric (or currently active) circuits’ MAX rates
in the tunnel.
Data transmission ranges
Table 12 provides the data transmission ranges for different cable types and port speeds for Fibre
Channel. Up to 500km at 1G is supported when using a long distance transport system such as DWDM.
Table 13 provides the data transmission ranges for different optical cable types and port speeds for
GbE SFP ports.
Table 14 provides the data transmission ranges for different cable types and port speeds for copper-
cabled GbE SFP ports and the fixed copper GbE RJ-45 ports.
