Client protection switch in optical pluggable transceivers activated through fast electrical data squelch

Abstract:

A pluggable optical transceiver includes one or more optical receivers; one or more optical transmitters; and a host interface communicatively coupled electrically to the one or more optical receivers and the one or more optical transmitters and communicatively coupled electrically via a plurality of pins to a host device, wherein, to disable one or more lanes of the one or more transmitters, a fast electrical squelch implemented in less than about 10 ms is utilized to turn off or turn on associated pins for the one or more optical transmitters. The pluggable optical transceiver can be a Quad Small Form-factor Pluggable (QSFP) type module.
