OFC 2021: 400ZR and 400ZR+ virtually everywhere and entering commercial reality

Lumenisity’s hollowcore fibre lab trials with Ciena were included in an OFC 2021 report created by global research leader, Omdia. The report stated:

Hollow-core fiber specialist, Lumenisity, announced lab trials using its CoreSmart fiber and commercially available Wavelogic 5 extreme (WL5e) and Wavelogic 5 nano (WL5n) products from Ciena. Lumenisity demonstrated reaches of more than 1,000 km at 400G WDM transmission in a recirculating loop. Although the loss of this fiber is still high relative to conventional single-mode fiber, it has several advantages. The first is low latency that happens in the hollow core fiber because the laser signals are traveling through air and not solid core silica glass. Its CoreSmart fiber increases the reach by 50% while maintaining the same latency. This can be very important in crowded metropolitan areas where data center locations can be very expensive. It may also play an important role for latency-sensitive 5G x-haul applications.

NEW HOLLOWCORE OPTICAL FIBre IS CLEARER THAN GLASS

Prof. Francesco Poletti explains how hollowcore fibre developed at the ORC (University of Southampton) matches or even beats the transparency of solid-core fibres in key wavelengths outside of the telecommunications band, where glass is most transparent. Read the IEEE Spectrum article here.


Hollowcore Optical Fibre Outperforms Standard Fibre at Shorter Wavelengths

On 27th November 2020, a paper was published in Nature Communications highlighting that NANF hollowcore fibre produced at the ORC (University of Southampton) can outperform standard fibres at short wavelengths. Find out more about this research here


Connecting the UK- Made in the UK.

The Photonics Leadership Group have outlined their vision of digitally compressing the UK. This means bringing regions up to 30% closer together, whilst doubling UK hardware content in networks and halving the UK digital carbon impact. Find out more here


OFC 2020: Hollowcore fibre advances towards exceeding telecom fibre limit

Researchers from the Zepler Institute for Photonics and Nanoelectronics at the University of Southampton, UK submitted a post deadline paper at the OFC in 2020. The paper highlights their latest findings in what they call “a new leap in hollowcore fibre performance” and involved close collaboration with Lumenisity.
