Abstract
Methods, circuits and active optical cable assemblies for simultaneous transmission of low-speed optical data and high-speed optical data over an optical fiber link are disclosed. In one embodiment, a method of optical communication includes controlling a laser such that an output of the laser transmits high-speed optical data at a first bit rate, and modulating an amplitude of the output of the laser such that the laser transmits low-speed optical data at a second bit rate simultaneously with the high-speed optical data. In another embodiment, a circuit for providing optical communication includes a laser and a laser driver circuit that digitally modulates an output of the laser to transmit high-speed optical data at a first bit rate. The circuit further includes an amplitude modulation circuit that modulates an amplitude of the laser to transmit low-speed optical data at a second bit rate simultaneously with the high-speed optical data.
