Flex System EN2092 1Gb Ethernet Scalable Switch 5Supported cables and transceiversIf the 10Gb Uplinks upgrade (49Y4298) is used or the client uses flexible port mapping to activate anexternal SFP+ port, then either SFP+ transceivers or DAC cables are required to provide outsideconnectivity. The following table lists supported SFP/SFP+ and DAC cable options.Table 3.

Clients that need longer distances canleverage the SFP/SFP+ external ports using a 1000BASE-SX transceiver which can drive distancesup to 220 meters using 62.5 μ multi-mode fiber and up to 550 meters with 50 μ multi-mode fiber or the1000BASE-LX transceivers that support distances up to 10 kilometers using single-mode fiber (1310nm).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 eachend, and they do not need separate transceivers. For longer distances the 10GBASE-SR transceivercan support distances up to 300 meters over OM3 multimode fiber or up to 400 meters over OM4multimode fiber with LC connectors. The 10GBASE-LR transceivers can support distances up to 10kilometers on single mode fiber with LC connectors.
