OPTICAL TRANSMITTER FOR TRANSMITTING A MULTILEVEL AMPLITUDE-SHIFT-KEYING MODULATED SIGNAL |
| 摘要 |
An optical transmitter for transmitting a multilevel amplitude-shift-keying modulated signal includes an optical modulator for modulating an optical signal with a multilevel amplitude-shift-keying modulation, and a spectral filter adapted to increase a high-frequency component of the modulated optical signal relatively to a central frequency component. The multilevel ASK modulation is quaternary ASK and the symbol rate of the optical modulator is above 40 Gbaud. An optical link connects the optical transmitter to a quadratic direct detection optical receiver. |
