Supported Cables And Transceivers - Lenovo RackSwitch G8124E Product Manual

Supported cables and transceivers

With the flexibility of the G8124E switch, clients can take advantage of the technologies that they require
for multiple environments:
For 1 GbE links, clients can use RJ-45 SFP transceivers with UTP cables up to 100 m. Clients that

need longer distances can use a 1000BASE-SX transceiver, which can drive distances up to 220
meters by using 62.5 µ multi-mode fiber and up to 550 meters with 50 µ multi-mode fiber, or the
1000BASE-LX transceivers that support distances up to 10 kilometers using single-mode fiber (1310
nm).
For 10 GbE links, clients can use direct-attached copper (DAC) SFP+ cables for in-rack 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.
Table 3 lists the supported cables and transceivers.
