摘要： An optical network communication system utilizes a coherent passive optical network (PON). The system includes an optical line terminal (OLT) having a downstream transmitter and an upstream receiver system configured for time-wavelength division coherent detection. The system further includes a splitter in operable communication with the OLT, and a plurality of optical network units (ONUs) in operable communication with the splitter. Each of the plurality of ONUs is configured to (i) receive downstream coherent burst signals from the OLT, and (ii) transmit at least one upstream burst signal to the OLT. The upstream receiver system further includes a power control module and a local oscillator (LO) configured to generate an optical LO signal The power control module is configured to adaptively control, in real-time, a power level of the optical LO signal.

摘要： 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.

摘要： A system and method of supporting access to content over first and second networks that allows a user to access content over different networks, either on the same device or with different devices. The access may be supported in a continuous or seamless matter without substantially interrupting access to the content, such as by instigating the transition during a period of time when minimal, if any content, or content of value, is likely to be missed.

摘要： A multiple access point system includes a wireless network including a first channel and a second channel. The system further includes a first access point and a second access point co-located within a single physical location environment, a wireless backhaul connecting the first and second access points to the wireless network, and a processor configured to (i) assign the first channel as a primary channel of the first access point and the second channel as a primary channel of the second access point, and (ii) assign the first channel as a secondary channel of the second access point and the second channel as a secondary channel of the second access point. The primary channel of the first access point does not overlap with the primary channel of the second access point, and the secondary channel of the second access point overlaps with the first access point.

摘要： A method for transmitting data through a multi-media communication network includes converting transmission entities into data symbols at a first communication device, transmitting the data symbols from the first communication device to a second communication device through at least two different types of communication media using only lower PHY layers of the at least two different types of communication media, and converting the data symbols into transmission entities at the second communication device. A network implementing a universal data link includes a first communication device configured to convert transmission entities into data symbols, a second communication device configured to convert the data symbols into transmission entities, at least a first communication medium and a second communication medium communicatively coupled between the first communication device and the second communication device, and a first physical-layer translator configured to translate data symbols without converting the data symbols into transmission entities.

摘要： An optical communication network includes a primary laser source, a first comb generator, and a first transceiver. The first comb generate a first plurality of comb tones having constant frequency spacing. The first transceiver includes a first transmitter having a secondary laser with a resonator frequency injection locked to a frequency of a single longitudinal mode corresponding to a particular comb tone of the first plurality of comb tones. The first transmitter adheres input data onto the injection locked frequency, and outputs a modulated data stream over an optical transport to a second transceiver downstream of the first transceiver. The improvement includes a second comb generator disposed downstream of, receives a seed tone from, and is phase-synchronized with, the first comb generator. The second comb generator outputs a second plurality of comb tones substantially conforming to the frequencies and frequency spacing of the first plurality of comb tones.

摘要： Managing wireless access points and/or other devices providing wireless signaling to multiple clients is contemplated. The wireless access point may be managed according to a load balancing strategy directed towards achieving desired network throughput using forced disassociation of clients based on traffic type or other service related indicators and/or force disassociation of roaming partners based on neighboring access point capabilities.
