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.

First Demonstration of Field-Deployable Low Latency Hollow-core Cable Capable of Supporting >1000km, 400Gb/s WDM Transmission

Trials undertaken by Lumenisity, Ciena and the University of Southampton report order-of-magnitude improvements in performance of field-deployable hollowcore fibre cables evidenced by a 38.4Tb/s (800Gb/s-x-48WDM-channels) 20.5km lab-trial using commercial terminal equipment and the demonstration of 1128km/126km reach in full-fill 400/800Gb/s WDM recirculating-loop experiments.

High-Frequency Traders Push Closer to Light Speed With Cutting-Edge Cables

High-frequency traders are using hollowcore fibre technology to speed up their systems by billionths of a second, the latest move in a technological arms race to execute stock trades as quickly as possible.


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.
