摘要： An optical drop-and-insert apparatus which can process an optical signal in the form of an optical signal without converting the optical signal into an electric signal. The optical drop-and-insert apparatus expands the pulse width of an optical data pulse in an optical data pulse train on an optical highway and drops the optical data pulse to form an empty bit at the bit of the optical data pulse or another bit so that a new optical data pulse may be inserted into the empty bit. Miniaturization of the apparatus and increase in processing speed can be attained by enabling processing of an optical signal while it remains in the form of an optical signal.

摘要： Using a switching signal from a coarse/fine switching and operation mode switching circuit, the width of change of a counter control value during power up is increased, and the width of change is reduced once a steady state is reached. In the steady state, the frequency of updating is limited by a control signal from an update permit control circuit. In the steady state, the frequency band of a current source in an LD driving circuit is reduced in width.

摘要： In a data decision circuit: a clock generation unit generates a clock signal based on a phase difference signal so that the clock signal has an optimum phase with respect to a phase of an input data signal; a data determination unit determines data values carried by the input data signal, by using the clock signal; a phase-difference detection unit detects a rising-side phase difference and a falling-side phase difference, where the rising-side phase difference is a phase difference between a rising of the input data signal and a next transition in the clock signal, and the falling-side phase difference is a phase difference between the transition and a next falling of the input data signal; and a phase-difference-signal generation unit generates the phase difference signal so as to represent a difference between the rising-side phase difference and the falling-side phase difference.
