Huawei Releases 600G Ultra-High-Speed Optical Network Solution

by September 13, 2018 0 comments

Huawei officially released a 600G ultra-high-speed optical network solution at the fifth Ultra-Broadband Forum (UBBF 2018). Based on Huawei’s latest OptiXtreme oDSP chips, the solution provides an adjustable single-wavelength rate of up to 600G and an industry-leading single-fibre capacity of 40T.

As cloud computing, big data, and AI technologies approach maturity, 5G is nearing commercialization and a large number of emerging services are increasing demands on network bandwidth. According to a report by independent analysis and consulting firm IHS, the per-bit transmission cost of optical networks began decreasing at an annual rate of around 30% upon the large-scale deployment of 100G in 2011.

However, as 100G/200G high-speed transmission technologies have continued to mature in the past 3 years, the decrease of per-bit cost has slowed down. To address dramatically growing bandwidth needs, operators are seeking ultra-high-speed transmission networks that minimize TCO and per-bit transmission cost.

Huawei is presenting its 600G ultra-high-speed optical network solution as an answer to such demands. The solution uses Huawei’s OptiXtreme oDSP chips and features an industry-leading spectral efficiency of 8 bit/s/Hz, 50% higher than the current single-wavelength 400G technology. This solution introduces the following improvements over the previous generation of high-speed transmission:

  • Higher single-wavelength rates: The single-wavelength rate is adjustable from 100G up to 600G, reaching the highest spectral efficiency in the industry. This variety of rates facilitates adaptation to all scenarios.
  • Increased transmission distance and transmission rate: The solution’s new channel-matched shaping (CMS) technology enables the transmission system to automatically match live-network channel environment and compensate for real channel impairments. This achieves optimal transmission performance while increasing the single-wavelength rate and reducing per-bit cost.
  • An AI neuron module: This new module performs real-time labelling and automatic performance optimization for all wavelengths in an optical network. Collaborating with Huawei’s Network Cloud Engine (NCE), the AI neuron module performs autonomous optimization and active protection for optical networks, as well as providing early warnings.

Huawei has been a major contributor to high-speed optical transmission for nearly a decade, establishing 17 optical network R&D centres around the world and partnering with operators worldwide to build high-speed transmission networks. In June of this year, Huawei won their second consecutive “Best Single-Channel Programmable 400G Product” award at the NGON conference in Nice, France, and performed the industry’s first live demo of the 600G solution.

“We are thrilled with the possibilities this solution presents,” said Richard Jin, President of Huawei Transmission Network Product Line. “We look forward to helping carriers achieve more success by maximizing fibre value, improving operation efficiency, and reducing TCO.”
