Abstract

Data is transmitted across an optical fiber communications system by modulating a stream of data into a stream of symbols (e.g., by using QAM modulation) and then frequency division multiplexing a number of symbol streams into a single high-speed channel to be transmitted across a fiber. The receiver reverses this process. In order to preserve the timing of the original data stream, on the receive side, the recovered data stream is synchronized to the received symbol stream, which in turn was synchronized to the original data stream on the transmit side. Thus, the recovered data stream is synchronized to the original data stream, preserving the original timing of the data stream.
