Abstract
Active Ethernet cables that provide data path redundancy. One illustrative cable embodiment includes a first connector connected to each of a second and third connectors, the first connector including a multiplexer that couples a data stream from a selectable one of the second and third connectors to an output of the first connector. One illustrative method embodiment includes: producing from an output of a first connector a data stream from a currently selected one of multiple redundant connectors; monitoring the data stream for a fault associated with the currently selected one of multiple redundant connectors; and responsive to detecting said fault, producing from the output of the first connector a data stream from a different selected one of the multiple redundant connectors.
