en.Wedoany.com Reported - The PEACE submarine cable, invested by Hengtong and built on a turnkey basis by its subsidiary HMN Tech, is becoming a communication system connecting Asia, Africa, and Europe with a total intercontinental backbone bandwidth of over 90T and an Open Cable architecture.
The continuous development of emerging business forms such as artificial intelligence, cross-border computing power scheduling, and digital trade is driving the growing demand for high-speed intercontinental connectivity. As the underlying core infrastructure of the optical communication industry and the global digital economy, international submarine cables support cross-continent computing power interconnection and global data flow. Meanwhile, about 40% of the world's submarine cables were built around 2000 and are gradually reaching the end of their lifecycle. The hardware foundation, architectural openness, and upgrade potential of a submarine cable system directly determine its ability to carry exponentially growing data traffic over the next 15 to 20 years.
The PEACE submarine cable is the only intercontinental cable system connecting Asia, Africa, and Europe that has been commercially deployed since 2022, featuring the latest hardware foundation and the greatest upgrade potential. The system spans over 22,000 kilometers, linking Asia, Africa, and Europe. In December 2022, the segments in France, Egypt, Kenya, and Pakistan were first put into commercial use; after the Singapore segment was delivered and connected in 2024, PEACE achieved full commercial operation from Singapore to France, providing a high-capacity, high-quality communication network with a latency as low as 136 milliseconds between Singapore and France.
The core highlight of the PEACE submarine cable is its pioneering large-scale commercial adoption of the Open Cable architecture. Leveraging HMN Tech's product technology, this architecture achieves complete decoupling of deep-sea underwater equipment from terrestrial terminal equipment. Core facilities such as the submarine cable backbone underwater equipment, Egypt's cross-border terrestrial cable, and the power supply transmission system determine link transmission stability, ultra-low latency performance, and a 25-year service lifecycle; the DWDM/SLTE transmission terminal equipment at terrestrial stations serves as standardized, replaceable, and upgradable upper-layer application modules, not bound to the cable's core facilities.
This architecture breaks the traditional submarine cable's situation of single-vendor binding, closed ecosystem, and limited upgradeability. Through ultra-large-capacity self-built infrastructure and full-category multi-platform compatibility, the PEACE submarine cable supports the connection of terrestrial communication equipment from different manufacturers. As of now, PEACE has fully integrated and stably commercialized DWDM/SLTE equipment platforms from multiple manufacturers, including Huawei, Nokia, Infinera, and FiberHome, for terrestrial stations. It has completed over a dozen station capacity expansions, supporting customers who purchase spectrum resources to independently light up and activate bandwidth services, making it one of the intercontinental submarine cable systems with the highest networking flexibility and strongest ecosystem inclusiveness in Asia, Africa, and Europe.
In terms of technological iteration, in 2024, PEACE collaborated with terminal station equipment vendors such as Huawei and Nokia to commercially deploy multi-generation high-speed transmission equipment at 400Gbps/500Gbps/600Gbps along the route, with sufficient technical redundancy reserved in the system. In 2025, PEACE supported a major operator customer in deploying 400GE end-to-end applications on the Asia-Europe route. With the application of Huawei's DWDM transmission equipment technology at terminal stations, the PEACE Egypt transit segment has completed the construction of a C+L band ultra-wideband platform and is about to undergo capacity expansion based on 800Gbps technology.
The PEACE submarine cable has established partnerships with multiple operators, including China Mobile, China Telecom, China Unicom, Orange (France), Telecom Kenya, Pakistan Cybernet, Telecom Egypt, and du (UAE). Looking ahead, PEACE plans to continue expanding deep-sea digital infrastructure, promoting capacity expansion and efficiency enhancement, advancing cutting-edge transmission technology iteration, and improving a multi-vendor compatible open service system.
