1. Four 10GE SFP+ optical ports

10GE SFP+ optical port

The card provides four 10GE SFP+ optical ports to transmit and receive service data at 1 or 10 Gbit/s. Table 5 lists the attributes of a 10GE SFP+ optical port.

When the card is installed on the S5720-HI, the four 10GE SFP+ optical ports support only 10GE SFP+ optical modules, SFP+ cables (1 m, 3 m, 5 m, and 10 m; SFP+ to SFP+), and AOC cables (3 m and 10 m; SFP+ to SFP+).

When the card is installed on the S6720-EI and S6720-C-SI, the four 10GE SFP+ optical ports support GE optical modules, GE copper modules, 10GE SFP+ optical modules, SFP+ cables (1 m, 3 m, 5 m, and 10 m; SFP+ to SFP+), and AOC cables (3 m and 10 m; SFP+ to SFP+).
