cabling for distances up to 7 m. These DAC cables have SFP+ connectors on each end, and they do not
need separate transceivers. For longer distances, the 10GBASE-SR transceiver can support distances up to
300 meters over OM3 multimode fiber or up to 400 meters over OM4 multimode fiber with LC connectors.
The 10GBASE-LR transceivers can support distances up to 10 kilometers on single mode fiber with LC
connectors. For extended distances, the 10GBASE-ER transceivers can support distances up to 40
kilometers on single mode fiber with LC connectors. With CX4 ports, client can use InfiniBand 4X copper
cables for distances up to 15 m.
The RackSwitch G8000 switch supports 10 GbE links with the optional dual-port SFP+ or CX4 uplink modules (see
Table 3). Up to two uplink modules can be installed per switch (one on the front panel and one on the rear panel).
Table 3 lists the supported cables and transceivers.
