Abstract:
1. An access multiplexer for multiplexing telecommunication signals, comprising: a housing; a passive multiplexer coupled to an optical line terminal of a telecommunication network via an optical fiber, the passive multiplexer configured to demultiplex a first multiplexed optical signal from the optical fiber thereby separating the first multiplexed optical signal into optical data signals; and an arrayed media converter having a plurality of optical network units that are situated in the housing and a plurality of modulation elements that are situated in the housing and coupled to conductive connections, the arrayed media converter configured to convert a plurality of the optical data signals into electrical signals, one of the optical network units having an optical receiver and a color adaptive optical transmitter, the optical receiver configured to receive and demodulate one of the optical data signals thereby recovering first data, one of the modulation elements coupled to the one optical network unit and a plurality of the conductive connections that extend from the one modulation element to at least one customer premises, the one modulation element configured to modulate a first plurality of electrical signals with the first data and to transmit the first plurality of electrical signals via the plurality of the conductive connections, the one modulation element configured to receive a second plurality of electrical signals and to demodulate the second plurality of electrical signals thereby recovering second data, the color adaptive optical transmitter configured to receive an optical seed signal and to modulate an optical signal with the second data, the color adaptive optical transmitter further configured to transmit, based on the optical seed signal, the modulated optical signal to the passive multiplexer at a wavelength of the optical seed signal, wherein the passive multiplexer is configured to multiplex the modulated optical signal with optical signals from the optical network units thereby providing a second multiplexed optical signal, the passive multiplexer further configured to transmit the second multiplexed optical signal to the optical line terminal via the optical fiber.
