Parallel optical transmitter/receiver module for data communications enables larger and longer transfer of data by detecting and/or correcting time displacements between parallel data channels

摘要

The module has a parallel optical transmission module with a displacement data transmission unit which can transmit parallel synchronous reference signals for a number of parallel data channels with a wavelength different from that of the data signals. The reference signals are transmitted with or without data signals. A displacement data receiver unit (45) in a receiver module (15) extracts the reference signals and can detect a displacement between the data channels on the basis of the reference signals.- DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an evaluation circuit
