Passive optical network using a fabry-perot laser as a multiwavelength source

摘要

A passive optical network (PON) comprises an optical device for producing light at a plurality of optical frequencies, an optical receiver for receiving light produced by the optical device, and a wavelength division multiplexer for transmitting the light produced by the optical device to the optical receiver, the wavelength division multiplexer having passbands centered at respective center frequencies, the center frequencies being different than the optical frequencies.
