摘要： In one example, an optical network access switch includes independent first and second banks of individually selectable optical inputs, as well as independent first and second groups of individually controllable optical outputs. A first multiplexer is connected to the optical inputs of the first bank and the optical outputs of the first group, and a second multiplexer is connected to the optical inputs of the second bank and the optical outputs of the second group. Finally, a configuration interface communicates with the first and second multiplexers and receives a switching command which specifies the connection/disconnection of an optical output to/from an optical input.

摘要： This disclosure concerns methods for calibrating optical emitters. For example, one calibration method is employed in connection with an optical transceiver that includes a laser. A range of temperatures is defined that includes low end and high end temperatures. At a first temperature, within the range, a first bias current to the laser is adjusted until the laser generates an optical signal at a first predefined power level. At a second temperature outside the range, a second bias current to the laser is adjusted until the laser generates an optical signal at a second predefined power level. If the second temperature is greater than the high end temperature, the second predefined power level is defined as less than the first predefined power level, and if the second temperature is less than the low end temperature, the second predefined power level is defined as greater than the first predefined power level.
