| 摘要 |
The invention is based on an optical transmitter (OT) for generation of an optical data signal (SO) out of at least two input modulation signals (MS1, MS2), comprising a laser source (LS) for generation of a laser signal (S20) to be modulated corresponding to said modulation signals (MS1, MS2), at least two optical modulators (EAM1, EAM2) for modulation of said laser signal (S20) according to said modulation signals (MS1, MS2), wherein said modulators (EAM1, EAM2) are optically connected in series to said laser source (LS) and the optical transmitter (OT) comprises a control mean to control said modulators (EAM1, EAM2) such, that the passing laser signal (S1) is modulated subsequently in cyclic order within defined nonoverlapping time windows, an optical modulation unit (OMU) and a method therefore. <IMAGE>
