The maximum length of fiber optic runs is limited to 300 meters. This is imposed by our use of
802.3X/802.1Qbb Priority Pauses. SFP-10G-LR is supported between fabric interconnect and FEX, but the
300 m limit still applies.
Note
QSFP Transceivers and Cables
The Cisco 6454 Fabric Interconnect supports Cisco 40GGBASE and 100GBASE Quad Small Form Factor
(QSFP) transceiver modules.
