Abstract
A novel weakly-coupled ultra low loss FMF is designed and fabricated, and the attenuations of all LP modes are less than 0.168dB/km. We demonstrate 4-mode MDM transmission over 20-km ultra low loss FMF with 10-Gb/s OOK modulation and direct detection. The transmission results indicate that the modal crosstalk during FMF transmission is very low. This novel FMF can satisfy the requirement of high quality MDM transmission systems in the future.
