摘要： A system, method, and computer readable medium for increasing an upstream optical coding gain in a passive optical network (PON). In an exemplary embodiment of the invention, the system may include a memory structured to store Optical Network Terminator (ONT) burst timing values, and provide a previous burst timing value of the burst timing values to a translator. Further, an upstream burst grant timing scheduler may provide a scheduled timing value to the translator, wherein the translator may be structured to translate the previous burst timing value to a new expected timing value per an ONT upstream burst in association with the scheduled timing value. Also, a delimiter match and search block may be structured to use the new expected timing value to check a bit stream for a delimiter pattern match. An alarm counter may be provided in the system that is structured to provide an alarm when the delimiter pattern match is not found.

摘要： An amplifier circuit in a PON and a method for using the same. The amplifier circuit may be used, for example in an ONU of the PON. In order to deal with varying customer requirements and the possibility of the ONUs or similar devices being installed at varying distances from the CO, a dynamically adjustable amplifier bias voltage is determined and applied to at least one amplifier in the amplifier circuit. The dynamic bias voltage is preferably a function of the input power to the ONU or the circuit output quality, or both. More than one dynamic bias voltage may be determined and applied in this fashion.

摘要： An xDSL modem having an adaptive hybrid termination impedance. The modem has a transformer with two cores, one connected to the modem's receiver and the other connected to the modem's transmitter. The two cores share an adjustable termination impedance. The modem determines which impedance setting to use, based on one or more measurements of channel loss, local echo power and received power from the far end transmitter, and the like.

摘要： The apparatus (10) includes a laser driver (16) that receives low speed and high speed digital and analog input signals (12, 14), and biases and modulates the laser diode (22) accordingly. The laser driver (16) receives and responds to input from a feedback circuit (36, 38), which includes an average power control portion (36), and a modulation power control portion (38). The average power control portion (36) of the feedback circuit generally determines the DC component of the laser diode output, and compares it to a reference average. The modulation power control portion (38) of the feedback circuit generally determines the maximum and minimum peaks in the laser diode output, takes their average and compares the average to the DC component of the laser output from the average power control portion (36). The laser diode (22) is then driven by the laser driver (16) in response to the comparisons.

摘要： An xDSL modem having an adaptively adjustable guard band comprising a finite number of spaced-apart frequency bins between the upstream and downstream frequencies. The guard band is adjusted by selecting one from among a plurality of filters belonging to a filter bank of the receiver circuitry. A weighted loss in data capacity is calculated when each of the candidate filters are used, and the filter which gives the lowest loss in data capacity, subject to certain criteria, is used. The adjustment is made pursuant to noise and signal characteristics measured during start or restart of an xDSL communications session.
