Zhang Xinquan, Cheng Rong, Yang Qi, et al. Research on intra-channel multiplexing schemes for Tbit/s optical transmission[J]. 2014,(4):1-4. DOI: 10.13756/j.gtxyj.2014.04.001.
As Tbit/s high-rate optical transmission has become a technological hotspot in the field of fiber-optic communication
this paper analyzes its key technology
intra-channel multiplexing.On the basis of comparing three technologies
i.e.NyquistWDM
OFDM and Super-Nyquist in terms of spectral efficiency
performance and feasibility
it gives the specific selection and presents an instructive technological solution to the commercial applications of Tbit/s high-rate optical transmissions.
