Recently, our company has made a breakthrough in scientific and technological achievements and successfully won the evaluation of "25G SFP28 80km Dual Fiber and BIDI for 5G Communication" as a leading scientific and technological achievement in China. This scientific and technological achievement represents an important progress of ETU-LINK in the field of optical communications, and is also a concrete manifestation of our commitment to technological innovation and serving the society. With the application and promotion of this product technology, it will further accelerate the construction and popularization of 5G networks and bring users a better and more efficient communication experience. 25G SFP28 80km Dual-fiberTechnology With its high-speed and long-distance transmission characteristics, provides a solid guarantee for the large-scale coverage of 5G communication networks. In long-distance communication links, data can still be transmitted stably and efficiently, greatly reducing signal attenuation and transmission delay, ensuring fast and accurate transmission of information. BIDI technology cleverly uses a single optical fiber to achieve bidirectional data transmission, which not only saves optical fiber resources and reduces wiring costs, but also improves the efficiency of optical fiber use. This advantage is particularly obvious in resource-constrained urban environments. This Achievement Has a Wide Range of Application Scenarios In the construction of smart cities, it can enable high-speed interconnection in all corners of the city and improve the level of intelligent urban management; in the field of telemedicine, it can achieve high-definition, real-time medical image transmission, making expert remote consultation possible; in the field of industrial Internet, it can help factories achieve efficient communication between equipment and promote the development of intelligent m anufacturing. ETU-LINK has always adhered to the concept of innovation-driven development and continuously explored new boundaries of optical communication technology. The achievement of this scientific and technological achievement (25G SFP28 80km dual-fiber and BIDI for 5G communication) is a strong proof of the company's R&D and technical strength. In the future, the company will further accelerate the promotion and application of scientific research results, use technological innovation as a strong engine, and drive the company to move forward at full speed towards the channel of high-quality development.

On April 22, 2025, the four-day 37th Russian International Communications Exhibition (SVIAZ) opened grandly at the Ruby Exhibition Center in Moscow. As the most influential communications technology event in Eastern Europe, this exhibition attracted 690 outstanding companies to gather together to draw a blueprint for the development of global communications technology. ETU-LINK exhibited products including but not limited to 100G Dual Fiber & BIDI Series Optical Modules, adjustable DWDM, 10G~400G DAC&AOC, etc. Each product embodies ETU-LINK deep thinking on the communications industry and fully demonstrates the innovative technology of R&D team. At the exhibition, ETU-LINK team had in-depth exchanges and negotiations with exhibitors and professional visitors from all over the world, learned about the latest demands and development trends of the international market, and also demonstrated to them the strength and style of Chinese optical communication companies. In this exhibition hall, the young lady of ETU-LINK walked gracefully in a new Chinese-style dress, attracting countless eyes. When walking, the hem of her skirt folded like an unfolded classical folding fan, condensing the oriental aesthetics of square and circle and auspicious meanings between the longitude and latitude. This exhibition not only expanded the international market, but also laid a solid foundation for the international development of the company. In the future, ETU-LINK will continue to adhere to the concept of customer-centricity, technology, products and services as the basis, and provide users with more systematic technical services and higher quality product services.
