摘要： An optical communication system comprises a network interface device (NID) having a media converter coupled to an optical fiber of a passive optical network (PON). The media converter converts optical signals from the PON into electrical signals for communication across at least one non-optical channel, such as a conductive or wireless connection, to customer premises equipment (CPE), such as a residential gateway or other customer premises (CP) device. Rather than implementing an optical media access control (optical MAC) layer in the NID, an optical MAC layer for handling PON protocols and management is implemented by the CPE, thereby effectively extending the customer end of the PON across at least one non-optical connection to the CPE. By implementing the optical MAC layer at the CPE, the complexity of the NID is reduced thereby lowering the cost of the NID. In one embodiment, in an effort to further reduce the complexity of the NID, the optical MAC layer is configured to control a laser-on state of an optical transmitter in the NID.

摘要： The present disclosure generally pertains to an arrayed media converter (AMC) that has an array of Wavelength Division Multiplexing-Passive Optical Network (WDM-PON) Optical Network Units (ONUs) for terminating an optical channel in the feeder or distribution portion of a telecommunication network. The ONU converts an optical signal from the optical channel into at least one electrical signal for transmission to a customer premises. Thus, the AMC serves as an interface between at least one WDM-PON link and at least one conductive connection, such as a twisted pair. In one exemplary embodiment, the AMC comprises a sealed housing that is environmentally hardened to protect the AMC from environmental conditions, including changes in weather. Such an AMC may be used to provide a robust, cost effective Fiber To The Curb (FTTC) solution, but the AMC may be used at other points within the network, if desired.

摘要： A correlation optical time domain reflectometer (OTDR) system embeds an OTDR signal in a digital data signal that is to be converted into an optical signal and transmitted across an optical fiber to a remote receiver. In particular, the digital data signal is amplitude modulated with the OTDR signal, which is based on a pseudo noise (PN) sequence, such as an M-sequence. The amplitude modulation is relatively small, for example, less than about 10% of the digital data signal's peak amplitude in an effort to limit the OTDR signal's effect on communication performance. A sequence recovery element receives reflections from the optical fiber and converts the reflections to digital samples. Each digital sample from the sequence recovery element is correlated by correlators that respectively correspond to delays and, hence, locations along the optical fiber, and accumulators accumulate the correlation values from the correlators. Based on the accumulated values, the correlation OTDR system unobtrusively identifies anomaly locations along the optical fiber while payload data is being communicated across the fiber.

摘要： A communication system has a trunk extending from a network facility, such as a central office, with a plurality of distribution points positioned along the trunk. Each leg of the trunk defines a shared channel that permits peak data rates much greater than what would be achievable without channel sharing. As an example, the connections of each respective trunk leg may be bonded. Further, the same modulation format and crosstalk vectoring are used for each leg of the trunk. The crosstalk vectoring cancels both far-end crosstalk (FEXT) that couples between connections of a given trunk leg and crossover crosstalk that couples between one trunk leg and another. In addition, logic determines an amount of excess capacity available for each leg of the trunk and controls error correction based on the determined excess capacity.

摘要： The present disclosure generally pertains to systems and methods for communicating data. In one exemplary embodiment, a system has a high-speed channel, such as an optical fiber, between a network facility, such as a central office (CO), and a first intermediate point between the network facility and a plurality of customer premises (CP). Digital communication links, such as DSL links, are used to carry data between the first intermediate point, such as a feeder distribution interface (FDI), and a second intermediate point, such as the Distribution Point (DP). Non-shared links may then carry the data from the second intermediate point to the CPs. The links between the two intermediate points are bonded to create a high-speed, shared data channel that permits peak data rates much greater than what would be achievable without bonding. In some embodiments, multicast data flows may be prioritized and transmitted across a set of connections to each of the intermediate points. In addition, it is possible to power components at the intermediate points from one or more of the CPs.

摘要： A communication system comprises a plurality of line cards having transceivers coupled to a plurality of subscriber lines. Each line card has at least one transceiver within the same vectoring group, and each line card also has vector logic capable of cancelling crosstalk induced by a tone communicated by any member of the vector group. Further, the line cards are coupled to one another via a data connection across which a vectoring stream carrying vectoring information from one line card to the next. The bandwidth of the vectoring stream is reduced by dynamically adjusting time slots of the vectoring stream based on bit loading for the communicated tones.
