A 500m length of Nested Anti-resonant Nodeless Fibre was presented at the European Conference of Optical Communications this month, it is the lowest loss ever measured in a hollow core fibre of any kind with a value of just 1.3 dB/km, and is shown to carry data. The breakthrough was also publicised in laser focus world.
We report fabrication of a Nested Antiresonant Nodeless hollow-core Fibre (NANF) with a minimum loss of 1.3dB/km at 1450nm and a 65nm bandwidth below 1.5dB/km. The 0.5-km long fibre is effectively single moded and is shown capable of data transmission.
