Ultrawide Bandwidth Hollow Core Fiber for Interband Short Reach Data Transmission

We report a Nested Antiresonant Nodeless hollow-core Fiber with 700nm bandwidth (1240–1940nm) and a minimum loss of 6.6dB/km at 1550nm. Penalty-free 100-Gb/s PAM4 data transmission from O- to L-band is demonstrated over ∼1km of fiber.
