Record-Low-Loss 83 μm 2 Effective Area Fiber and Transmission of 40x369 Gb/s Channels over a Trans-Atlantic Submarine Link with 101 km Spans

We present optical fiber with 83 μm2 effective area and record-low attenuation of 0.1522 dB/km. We conduct experiments with 404 km of fiber in 101 km spans, demonstrating trans-Atlantic system transmission with 369 Gb/s channels. © 2021 The Author(s)
