Abstract
An optical power distributor is coupled to a high-intensity broadband light source to distribute in a shared manner an output of the high-intensity broadband light source to a plurality of optical line terminals. A depolarizer is also described having an input coupled to an output of a polarized broadband light source. A first integrated module has optical transmitters and an optical wavelength router for a first band. A second integrated module has optical receivers and an optical wavelength router for a second band.
