The bidirectional couplers are configured to at least partially obtain a second data stream that includes at least the first data component and to obtain a third data stream that includes at least the second data component. In some embodiments, the bidirectional couplers may include a signal separation module or stage that is configured to further separate the first and second data components.

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： An apparatus and method are provided for setting the AC and DC bias levels of a laser diode in an optoelectronic transceiver so as to control the device's extinction ratio. An optical output of the transceiver is looped back to an optical input of the transceiver. The method includes setting a DC bias level for the laser diode, setting an AC bias level for the laser diode to each of a predefined sequence of AC bias level settings, and receiving from the transceiver a sequence of optical output power measurements, the sequence of optical output power measurements including an average optical output power measurement corresponding to each of the AC bias level settings in the predefined sequence. From the received sequence of optical output power measurements preferred AC and DC bias level settings are determined and stored in the transceiver so as to control the AC and DC bias levels of the laser diode.
