Title: METHODS AND APPARATUSES TO PROVIDE A WAVELENGTH DIVISION-MULTIPLEXING PASSIVE OPTICAL NETWORK BASED ON WAVELENGTH-LOCKED WAVELENGHT-DIVISION- MULTIPLEXED LIGHT SOURCES
Abstract:
Various methods, systems, and apparatuses in which a wavelength-division-multiplexing passive-optical-network includes a first broadband light source and a second broadband light source. The first broadband light source supplies an optical signal containing a first band of wavelengths to a first plurality of optical transmitters. The second broadband light source supplies an optical signal containing a second band of wavelengths to a second plurality of optical transmitters. A fiber is used for bi-directional transmission of optical signals in at least two different wavelength bands.
