摘要
A few-mode fiber (FMF) is designed to support three spatial modes (LP01, LP11a, and LP11b) 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 200 Tb/s (375×3×178.125 Gb/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.
