Low loss, large bandwidth antiresonant hollow-core fiber design for short-reach links

Published date: March 2020

Additional Information: Funding Information: Besides, one might think of exploiting the wide optical bandwidth and low chromatic dispersion of the fibres to implement WDM at low baud rates, in combination perhaps with higher order modulation techniques that can address the limitations imposed by such relatively high DGD. Orthogonal Frequency Division Multiplexing (OFDM) for example, is a format that is known to be resilient to multipath interference [10]. 4. Conclusions We have presented an approach to achieve low loss, multi-mode operation of hollow-core, antiresonant fibres based on the ALIF structure. Using this approach, a series of fibres were designed with increased multi-mode content. A fibre with twice the bandwidth of the current generation of GI fibre targeting WDM for short-reach datacoms was chosen as the best trade-off. This geometry guides 7 mode groups, or a total of 24 modes, with losses under 0.6 dB/km. Although the single channel data rate is likely inferior to DGD optimised GI fibre due to a large DGD, the proposed fibre has the potential to achieve 100 Gb/s data rate or better using WDM over its increased bandwidth. OFDM is suggested as a modulation format to mitigate the effects of DGD in which case the bandwidth could be used to achieve 200 Gb/s or greater data rates.
