Robust BPSK Impulse Radio UWB-over-Fiber Systems Using Optical Phase Modulation
Coherent communications Radio frequency photonics
2015/5/22
The impact of fiber dispersion on the performance of optical phase modulated impulse-radio-ultrawideband (IR-UWB) signals is experimentally investigated. 2Gbps BPSK IR-UWB over 78km fiber transmission...
40 Gb/s Carrierless Amplitude and Phase Modulation for Low-Cost Optical Datacommunication Links
Fiber optics communications Modulation
2015/5/22
4 bps/Hz 40 Gb/s carrierless amplitude and phase (CAP) modulation is investigated for next-generation datacommunication links. The 40 Gb/s link achieves double the length of a conventional NRZ scheme,...
Continuous Phase Modulation as an Alternative to QPSK for 100 Gb/s Optical Links
Fiber optics communications Coherent communications
