Frontplane communication network between multiple pluggable modules on a single faceplate

Abstract:

A pluggable module includes an interface configured to connect to a connector associated with a device having internal circuits; an optical interface configured to connect to a network path, to enable communication between the internal circuits and the network path; and a signal interface configured to connect to a second pluggable module in the device, wherein the signal interface connects to the second pluggable module as an out-of-band channel that operates independently from a backplane of the device and the internal circuits.
