More Information
Summary:A few-mode fiber （FMF） is designed to support three spatial modes （LP01, LP 11a, and LP 11 b） and fabricated through plasma chemical vapor deposition （PCVD）and rod-in-tube （RIT） method. Using PDM-DFTS-OFDM- 32QAM modulation, wavelength division multiplexing, mode multiplexing, and coherent detection, we successfully demonstrated 200Tb/s （375× 3 × 178.125Gb/s） signal over 1 km FMF using C and L bands with 25 GHz channel spacing. After 1 km FMF transmission, all the tested bit error rates （BERs） are below 20% forward error correction （FEC） threshold （2.0 × 10-2）. Within each sub-channel, we achieved a spectral efficiency of 21.375 bits/Hz in the C and L bands.
