Abstract
A data transport system for transporting data and auxiliary signals over an optical link comprises a transmitter, a receiver and an optical link. The transmitter and receiver are coupled to a first end of the optical link. The optical link includes a number of optical channels. A controller is coupled to the transmitter and the receiver, and controls the transmitter and the receiver to operate in a first state when data are detected at an input of the transmitter. Data are transported via the data transport system in the first state. The controller controls the transmitter and the receiver to operate in a second state when the data are detected as absent at the input of the transmitter. Data are prevented from being transported via the data transport system in the second state.
