Supported Cables And Transceivers - Lenovo Flex System EN2092 Product Manual

Supported cables and transceivers

If the 10Gb Uplinks upgrade (49Y4298) is used or the client uses flexible port mapping to activate an
external SFP+ port, then either SFP+ transceivers or DAC cables are required to provide outside
connectivity. The following table lists supported SFP/SFP+ and DAC cable options.

With the flexibility of the EN2092 switch, clients can take advantage of the technologies that they require
for multiple environments:
For 1 GbE links, you can use RJ-45 UTP cables up to 100 m. Clients that need longer distances can

leverage the SFP/SFP+ external ports using a 1000BASE-SX transceiver which can drive distances
up to 220 meters 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 (supported on external SFP+ ports), you can use direct-attached copper (DAC) SFP+

cables for in-rack cabling and 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.
