    Abstract: Systems and methods presented herein provide for optical communications. In one embodiment, a communication system includes a plurality of communication nodes and a communication hub. A bundle of optical fibers optically links the nodes to the communication hub. The communication hub includes a laser operable to propagate unmodulated laser light to a first node along a first of the optical fibers in the bundle. The first node is operable to modulate the laser light with a first modulating signal source, and to propagate the modulated laser light to a second node. The second node is communicatively coupled to a second modulating signal source and to the first node. The second node is operable to optically combine upstream communications from the second modulating signal source with the modulated laser light from the first node, and to propagate the modulated laser light with the upstream communications to the communication hub at a same carrier wavelength.

    Abstract: A method to capture random data signals at an end point in a broadband network and process them via digital signal processing (DSP) techniques to determine both linear distortions and nonlinear distortions. In a distribution network, such as a tree and branch cable network, the location of the impairment addition can be identified by determining location of terminals have a distortion and locations of terminals that do not have a distortion. Linear distortions may be determined by an autocorrelation of the captured signal with itself. Nonlinear distortions may be determined by processing measured energy in a vacant band with manufactured energy in the vacant band. If a vacant band is not available, one can be created by demodulating a signal occupying the band, and subtracting the demodulated signal from the measured signal plus interference in a band, leaving only the interference.

    Abstract: A coherent passive optical network extender apparatus includes an extender transceiver for communication with an associated optical headend. The extender transceiver includes at least one receiving portion, at least one transmitting portion, and an extension processor. The apparatus further includes a signal adaptation unit configured to convert a downstream electrical transmission lane into a plurality of individual wavelengths. Each of the converted individual wavelengths are for transmission to one of an optical node and an end user. The apparatus further includes a plurality of transceivers, disposed within the signal adaptation unit, and configured to process and transmit the converted individual wavelengths as a bundle for retransmission to the respective end users.
