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.

Abstract: Client-side protection systems and methods are implemented by a network element using a fast electrical squelch with a first optical transceiver and a second optical transceiver. A client-side protection method includes detecting a protection switching event affecting one or more lanes associated with the first optical transceiver; causing a fast electrical squelch to the affected one or more lanes of the first optical transceiver to provide a Loss of Signal (LOS) thereto; and subsequent to the LOS to the first electrical transceiver, causing a fast electrical squelch to corresponding one or more lanes of the second optical transceiver to enable the corresponding one or more lanes thereon.
