摘要： An optical RZ transmitter comprises an optical signal source and a pair of electro-optical modulators in tandem, one arranged to receive a NRZ electrical data signal and the other a clock signal at the data rate of the data signal. The phase difference between the data signal and the clock signal is controlled by adding a first dither signal to a bias signal applied to the modulator receiving the data signal, and a second dither signal, having a different frequency, to the phase difference. The amplitude of variations in the power of the optical output signal corresponding to cross-modulation of the first and second dither signals is detected and the phase difference is controlled in response to the detected amplitude.

摘要： The invention includes a method for processing messages at a component. One method includes receiving a message formed according to an embedded protocol or an external protocol, processing a portion of the received message for identifying the protocol used to form the message, and processing the received message using the identified protocol. The portion of the received message is formed using a comparison between at least one characteristic associated with the embedded protocol and at least one characteristic associated with the external protocol. Another method includes receiving, at a first type-one component, a message from one of a second type-one component or a type-two component, processing a portion of the message for identifying a protocol adapted for processing the received message, and processing the received message using the identified protocol.

摘要： Techniques to control an optical receiver having a control loop using Bit Error Rate (BER). In one implementation, a bit error rate (BER) associated with a received optical signal is determined. Indication of the BER to a control loop adapted is provided to adjust the optical signal in a manner tending to reduce the BER. The received optical signal is adapted in a manner tending to increase the BER such that the control loop operates within an active control region.
