Lenovo G7028 Product Manual page 6

For 10 GbE links (supported on SFP+ ports), customers can use direct-attached copper (DAC)
SFP+ cables for in-rack cabling for distances up to 7 meters. 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. The 10GBASE-LR
transceivers can support distances up to 10 kilometers on single mode fiber.
The supported SFP/SFP+ and DAC cable options are listed in the following table.
