On June 10, Huawei has publicized that with the cooperation of leading European operators successfully completed the industry’s first Dense Wavelength Division Multiplexing (DWDM) live network test with a single-wave rate of 1.66Tb/s.
What is DWDM?
Dense Wavelength Division Multiplexing (DWDM) is an optical multiplexing technology used to increase bandwidth over existing fiber networks. It works by combining and transmitting multiple signals at the same time at different wavelengths on the same fiber.
The test aims to research cutting-edge technology based on a large-capacity data center interconnection (DCI) scenario. It uses a standard G.652 fiber of 96.5 km and only ordinary EDFA optical amplifiers throughout the process.
Testing process and achievements:
During the test, a total of 34 channels were transmitted on the live network and each channel separated by 150GHz and the total fiber capacity exceeded 56Tb/s, as well as the spectral efficiency, exceeded 11bit/s/Hz.
At the same time, this live network test also completed a single-wave transmission of 1.77 Tb/s over 60 km, a single-wave transmission of 1.65 Tb/s over 120 km, and a single-wave transmission of 1.6 Tb/s over 180 km.
These record-breaking results are achieved through Huawei’s advanced CMS (channel-matched shaping) algorithm. It includes advanced nonlinear digital signal processing technology, high-order modulation technology based on 400QAM, and uses enhanced probability constellation shaping (ePCS).
To be mentioned, it also uses a deep neural network drive algorithm to always maintain the most advanced signal processing capabilities, thereby achieving excellent transmission performance.
Additionally, this test also verified the transmission capability of the metropolitan area network based on ROADM. In the G.652 fiber-optic network of 452 km on the existing network, Huawei successfully achieved a single-wave transmission rate of 1.28 Tb/s without an electrical relay. As well as the entire process only uses an ordinary EDFA optical amplifier.
Regarding this, Dr. Maxim Kuschnerov, Director of Huawei’s Optical and Quantum Communications Laboratory, said:
“We have achieved an important milestone in the single-wave 1.6 Tb/s transmission era in DCI and metropolitan area networks.
With Super C+L spectrum innovation, future single-fiber transmission capacity will be achieved. It will exceed 100Tb/s, thus providing sufficient support for the continuous growth of network traffic in the future.”
Huawei brings 5G to fishing boats
Recently, China Unicom Guangdong and the 5G Huawei “Digital Fishing Boat” project won the 2023 GSMA “5G Productivity Challenge Award” by installing 5G to fishing boats for various use cases.
This achievement includes efforts of the two companies to jointly create new 5G technologies, build a 5G operation ecosystem, and promote industrial digitalization through the “5G Fast City” while ensuring the growth of 5G applications.
David Pringle, a GSMA judge and a senior analyst at Pringle Media, pointed out: “On the more than 450 kilometers of coastline in Yangjiang City, Guangdong Province, 5G is completely changing the lives of fishermen, allowing them to keep abreast of weather conditions, sell fish and other products when they go fishing. Stay connected with your family. Guangdong Unicom’s digital fishing boat system has provided services for more than 4,000 fishing boats, and it can also assist the local fishery administration to mitigate the impact of typhoons and combat illegal fishing operations.”
Guangdong Unicom and Huawei used China Unicom’s 5G private network PLUS product system to develop the 5G digital fishing boats system.
Using 5G, cloud computing, the Internet of Things, and Beidou positioning technologies, it can realize all-weather dynamic monitoring of fishing boats’ offshore operations. Through the 5G MetaAAU ultra-large-scale antenna array, the system gives full play to the advantages of the large bandwidth of the 3.5G frequency band, and can still maintain the access capability of 60Mbps downlink and 2Mbps uplink in the 61km far sea range.
On the “digital fishing boat”, fishermen can not only watch the news, but also keep abreast of weather warnings and other information, and make high-definition video calls with their families. In the event of an emergency on the fishing boat, fishermen can call for help with one click through the app and get assistance in time. Fishermen can also use the app to link to major e-commerce platforms and sell seafood products across the country through e-commerce channels.
Guangdong Unicom plans to further promote the digital fishing boat system and provide related services for 40,000 to 50,000 fishing boats in Guangdong Province. At the same time, Guangdong Unicom and Huawei also plan to carry out innovative cooperation with industrial partners in the fields of offshore wind power, offshore pastures, and island tourism through the “5G Fast City”.
