摘要： When merging optical pulse streams having a high bit rate, there is the problem that, for example given a bit rate of 40 Gbit/s, the pulses at the multiplexer output have 25 pulses temporal spacing and approximately 5 mm spatial spacing. Given a precision of 10% of the bit rate, the light waveguides must be matched with a precision of 0.5 mm, which previously required mechanical or inserted length-adjustable open beam optics and which leads to high outlay. In the optical delay line, by contrast, the temperature of a light waveguide is varied such that the desired optical length is set via the change in the refractive index of the optical fibers. The optical fibers are wound on coil bodies that have a through bore containing a heating element connected to a temperature control.

摘要： A subcarrier system generates a phase comparison signal in a transmitter and transmits the phase comparison signal together with an optical subcarrier multiplex signal in the same transmission channel of an optical network. A receiver measures a phase distortion between a phase reference signal and the received phase comparison signal for each modulation section of the received subcarrier symbols, calculating at least one correction value and correcting time jitters or phase impairments of all parallel received or regained subcarrier symbols as a function of the phase distortion of the received phase comparison signal. Time jitter/phase jitter can be compensated without high hardware expenses.
