Recently, the SDN-based new metro wavelength division multiplexing (WDM) system independently developed by Sino-Telecom has successfully passed the authoritative scientific and technological achievement evaluation conducted by the China Institute of Communications (CIC), with an official evaluation report issued. After rigorous review by industry experts, the achievement has been recognized as internationally advanced in technology, effectively addressing key challenges in computing power network transmission and providing efficient, reliable solutions for data center interconnection (DCI) and metro optical network upgrades.
Focusing on Computing Power Demand, Resolving Industry Transmission Bottlenecks
With the rapid development of the computing power economy and the in-depth implementation of the “East Data, West Computing” project, demand for cross-regional data transmission and computing power scheduling has grown substantially. Traditional metro transmission equipment faces bottlenecks including limited bandwidth, high costs, and complex operation and maintenance, which can no longer satisfy the requirements for efficient large-capacity data transmission.
By addressing these industry challenges through continuous research and development, Sino-Telecom has developed this SDN-based new metro WDM system to enhance transmission performance, unblock cross-regional computing power flows, and support the upgrade of digital economy infrastructure.
Robust Product Performance Balancing Efficiency and Cost Optimization
Based on the core technologies validated in this evaluation, Sino-Telecom has launched its corresponding DCI system (DCI-BOX STN6800-D16). Designed for efficient deployment and simplified operation, the product adopts a high-density, low-power modular architecture that improves single-fiber transmission efficiency, reduces equipment room footprint, and lowers energy consumption and O&M costs.
Equipped with an intelligent management and control platform, the DCI-BOX supports real-time link monitoring, fast fault response, and flexible service scheduling, with easy deployment and high compatibility. Compared with conventional transmission equipment, it delivers clear advantages in deployment cost, O&M efficiency, and scenario adaptability, making it well-suited for diverse computing interconnection scenarios including telecom carriers, cloud providers, enterprises, public institutions, and financial organizations.
Large-Scale Market Deployment with Wide Recognition
Supported by CIC’s authoritative evaluation and proven product performance, the solution has been widely deployed in the market. It has been successfully applied in key projects including metro backbone network upgrades for multiple carriers, data center interconnection for large enterprises, and the construction of computing power hubs, covering major digital economy regions such as the Beijing-Tianjin-Hebei Region, the Yangtze River Delta, and the Guangdong-Hong Kong-Macao Greater Bay Area. At present, this DCI-BOX has seen large-scale deployment by mainstream telecom operators, including China Telecom and China Unicom. With its stable performance and high-quality services, it has gained wide recognition from customers and the industry, with cumulative shipments exceeding 100,000 units.
During stable operation, the system delivers consistent performance, helping customers lower TCO (Total Cost of Ownership) and improve data transmission efficiency. It has earned strong market recognition and broad application prospects.
Deep Commitment to Optical Communications, Empowering Digital Transformation
The successful completion of this scientific and technological achievement evaluation by the national-level industry institute serves as authoritative recognition of Sino-Telecom’s R&D capabilities and product value.
Going forward, the company will continue to focus on optical communications and computing power networks, accelerate the industrial application of its core technologies, and deliver more advanced transmission solutions to empower digital transformation across industries and strengthen the foundation for high-quality digital economic development.
