We report on two recirculating loop transmission experiments over a hollow-core fiber of the Nested-Antiresonant Nodeless type (NANF). transmitted 61 channels in C-band at 32 GBaud, with either PM-QPSK or PM-16QAM modulation. In addition, L-band interferers co-propagated NANF all times, though they were not recirculated loop, to check for presence possible crosstalk effects between C and NANF. ...

As internet traffic demand continues to increase, high-speed electro-optic modulators and high-bandwidth RF components are needed stretch intensity modulation direct detection (IMDD) systems their limits. In this study, we experimentally demonstrate the transmission performance using next generation of digital-to-analog converters (DAC) thin-film lithium niobate (TFLN) modulators. C-band, trans...
