Abstract: A baseband processing unit includes a baseband processor configured to receive a plurality of component carriers of a radio access technology wireless service, and a delta-sigma digitization interface configured to digitize at least one carrier signal of the plurality of component carriers into a digitized bit stream, for transport over a transport medium, by (i) oversampling the at least one carrier signal, (ii) quantizing the oversampled carrier signal into the digitized bit stream using two or fewer quantization bits.

Abstract: Generating an assessment of the suitability of cables, ducts, tubes, pipes and/or other hollow-type of conduits to extraction of cores, conductors, insulation, etc. included therein while still buried in the ground or otherwise positioned out-of-sight so as to be unavailable for visual and/or physical inspection is contemplated. The assessment may be used to indicate a suitability of a cable buried in the ground of a hybrid fiber coaxial (HFC) cable plant to extraction of the type whereby a core of the cable may be extracted using hydraulics while still buried.

Abstract: An optical network includes a transmitter portion configured to (i) precode an input digitized stream of symbols into a precoded symbol stream, (ii) pulse shape the precoded symbol stream with an eigenvalue channel matrix, and (iii) transmit the pulse shaped symbol stream over a digital optical link. The optical network further includes a receiver portion configured to (i) recover the pulse shaped symbol stream from the digital optical link, (ii) decompose eigenvalues of the eigenvalue channel matrix from the recovered symbol stream, and (iii) decode the decomposed symbol stream into an output symbol stream.

Abstract: An optical network communication system includes an optical hub, an optical distribution center, at least one fiber segment, and at least two end users. The optical hub includes an intelligent configuration unit configured to monitor and multiplex at least two different optical signals into a single multiplexed heterogeneous signal. The optical distribution center is configured to individually separate the at least two different optical signals from the multiplexed heterogeneous signal. The at least one fiber segment connects the optical hub and the optical distribution center, and is configured to receive the multiplexed heterogeneous signal from the optical hub and distribute the multiplexed heterogeneous signal to the optical distribution center. The at least two end users each include a downstream receiver configured to receive one of the respective separated optical signals from the optical distribution center.

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.
