High-capacity WDM Coherent Transmission over Hollow-core Fiber

In this paper, we experimentally demonstrate a wavelength division multiplexing (WDM) coherent transmission of 20-channel 60 GBaud dual-polarization 16-level quadrature amplitude modulation (DP-16QAM) signals over 342 m homemade nested anti-resonant nodeless fiber (NANF). To our best knowledge, we achieve a record NANF transmission of net bit-rate of 448.6 Gbit/s per wavelength and net capacity of 8.97 Tbit/s, respectively.
