Apparatus and methods for nulling non-random timing jitter in the transmission of digital optical signals

摘要

A clock recovery circuit for following rapid changes in the time phase of a data stream is disclosed. The circuit comprises a low Q resonator coupled to a detection device, such as an electro-optic modulator in a time division demultiplexer or a decision circuit of a receiver. Preferably, a high Q resonator or phase locked oscillator is provided, as well. The present invention is particularly useful in a telecommunications system for transmitting solitons. A method of compensating for changes in time phase of a data stream is also disclosed.
