Modern fiber-optic communication systems generally include optical transmitters that convert electrical signals into optical signals, optical fiber cables to carry the signal, optical amplifiers, and optical receivers to convert the signal back into an electrical signal. The information transmitted is typically digital information generated by computers or telephone systems.
We experimentally demonstrate integrated sensing and communication over 480-km single-mode fiber with low-cost 12.5-MHz linewidth DFB laser, achieving single-wavelength 1.07-Tb/s transmission with
