Abstract:
1. A device comprising: a transmitter coupled to a first end of an optical link that includes a plurality of optical channels, the transmitter includes a plurality of channels and a plurality of drivers corresponding to the plurality of channels; a receiver coupled to the first end of the optical link, wherein a data transport system comprises the transmitter, the receiver, and the optical link; a controller to control the transmitter and the receiver to operate: a detector coupled between an input of the transmitter and the controller, wherein the detector outputs a detector signal representative of a parameter of a signal at the input, wherein the controller detects an idle state using the detector signal and in response disables data transmission over the data transport system; wherein the first signal configuration includes at least one first code that indicates the transmitter and the receiver are properly configured to transport the data; the at least one first code is represented by combined states of the plurality of auxiliary signals and is a member of a first code set that includes a first plurality of binary codes; the second signal configuration includes at least one second code that indicates the transmitter and the receiver are improperly configured to transport data; the at least one second code is represented by the combined states of the plurality of auxiliary signals and is different than the at least one first code; the controller selectively enables and disables the plurality of drivers to generate the at least one first code and the at least one second code; the data includes first data signals and second data signals; the plurality of auxiliary signals includes first auxiliary signals and second auxiliary signals; the transmitter operates: the receiver operates:
