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： An optical communication system has a power dissipating element that is thermally coupled to an optical transmitter. The currents supplied to the transmitter and the power dissipating element are controlled such that the sum of such currents is constant. Accordingly, temperature fluctuations in the transmitter due to patterns in the transmitted data are prevented or at least reduced, thereby reducing thermal tails on measurements. In one exemplary embodiment, a light source is used as the power dissipating element, and the output of such light source is beneficially used to probe another optical fiber or to enhance the OTDR performance or analysis.

摘要： An optical communications system includes a MSAP and an optical transceiver mounted at the MSAP that communicates over an optical network to at least one optical network terminal (ONT). A first electronic module is operatively connected to the optical transceiver and configured to control the optical transceiver and mounted at the MSAP separate from the optical transceiver. A redundant second electronic module is supported within the MSAP and mounted separate from the optical transceiver. A Mux/Demux module interconnects and supports the first and second electronic modules to form an integral unit and mounted at the MSAP separate from the optical transceiver. The Mux/Demux module is configured to switch the second electronic module into communication with the optical transceiver upon failure of the first electronic module.
