OPTICAL RZ DATA SIGNAL GENERATOR AND CORRESPONDING METHOD

摘要

The invention relates to an optical RZ data signal generator and to a corresponding method for generating optical RZ data signals (ORZ) in optical networks. A simple addition of an electric pulse signal (IS) with an electric NRZ data signal (NRZ) results in an association signal (AS) that yields a high-extinction optical RZ signal (ORZ) when controlled by a controllable optical source (4) with a non-linear control characteristic (K).
