Huawei Completes Industry's First Live Demo of a 600G Single-Wavelength Ultra-High-Speed Optical Transmission System

[Nice, France, June 26, 2018] Today, Huawei announced the completion of the industry's first live demo of a 600G single-wavelength ultra-high-speed optical transmission system at the Optical Network Innovation Forum 2018. Based on Huawei's latest optical transmission platform, the system adopts Huawei's own unique channel-matched shaping (CMS) technology and an AI neuron module designed for optical networks. Boasting an adjustable single-wavelength rate of up to 600G and a single-fiber capacity of 40Tbit/s, the system can further improve the efficiency of network operations and enable smooth evolution from existing traditional networks to intent-driven networks.

Taking advantage of the rapid development of technologies such as 5G, cloud computing, and Big Data, the optical network industry has fully entered the ultra-high-speed era. According to a report by independent analyst and consultancy firm Ovum, Huawei shipped over 127,000 100G+ ports in 2017, which was more than 1/3 of the total shipments for the global optical network market. Today, 200G is maturing and 400G and 600G are nearing commercialization. The coherent oDSP algorithm is the core technology that powers and commercializes ultra-high-speed optical transmission. It provides core functions such as modulation and demodulation of higher-order modulation signals, multiplexing of polarized optical signals, compensation for fiber link damage, and signal clock recovery. Such importance makes coherent oDSP a critical arena of competition for all vendors in the industry.

The 600G single-wavelength ultra-high-speed optical transmission system adopts Huawei's latest coherent oDSP algorithm, which improves the performance from the following aspects:

50. Ultimate transmission capacity and distance: This is the first time the CMS technology has been introduced in a transmission system. CMS improves the equivalent bandwidth of transmission links, satisfying the requirements of high-speed transmission channels and maximizing the spectral efficiency. By leveraging CMS, the system features the industry's best-performance transmission at 400G to 600G single-wavelength rates, increasing single-fiber capacity by a maximum of 50% to 40T and transmission distance by 30–50%.
50. Optimal power consumption efficiency: The industry-leading 16-nm FinFET manufacturing technique and simplified chip architecture reduce the power consumption per bit by 30%.
50. More intelligent: Huawei's unique built-in AI neuron module enables smooth upgrade to the intelligent management and control of optical networks. Using the optical-layer labeling technology and oDSP algorithm, the module performs real-time labeling, detection, and data collection for all wavelengths directly at the optical layer on the optical transmission network. This eliminates the need for any additional modules or optical-to-electrical conversion processes. In addition, the AI algorithm of the Huawei Network Cloud Engine (NCE) platform provides functions like autonomous optimization, self-protection, and advance warnings of performance deterioration for optical networks. These features help carriers smoothly evolve their traditional networks to intent-driven networks.

Richard Jin, President of Huawei Transmission Network Product Line, said, "Huawei has long been leading the field of 100G, 200G, and 400G ultra-high-speed optical transmission, thanks to our strategic investment in optical networks. The new 600G system provides AI capabilities for optical networks, using Huawei's sixth-generation coherent oDSP algorithm and an additional optical-layer AI neuron module. This will help our customers build intent-driven networks based on user experience."
