In this digital era, information transmission has become an indispensable part of modern society. With continuous technological advancements, urban area network applications have brought us greater convenience and possibilities. Let's delve into an inspiring case of urban area network application that establishes a 40x200G transmission system for clients.

Client's Needs

In a city with a substantial demand for information flow, the client aspired to establish a high-speed and reliable transmission system to meet the demands of extensive data transfer. Through in-depth research and analysis, we discovered a practical solution.

The Solution 

we opted for DCI technology as the foundation. DCI technology utilizes high-speed optical fiber connections between data centers to achieve swift data transmission and efficient management. In this case, we established a 40x200G transmission system to fulfill the client's requirements.

To ensure reliability and fault tolerance in transmission, we implemented the D16HE network scheme. D16HE is a high-density networking architecture capable of supporting large-scale data transfer. By connecting multiple transmission nodes to form a circular network, data can be swiftly transmitted and seamlessly switched.

In this case, the distance around the loop is approximately 200km. We employed Och protection, an optical channel protection technology that automatically switches to a backup optical fiber link in case of a failure in the optical fiber link, ensuring continuous data transmission and data reliability. 

Introduction to Relevant Products
In this case, we primarily utilized two product types: STN6800-D16HE and STN6800-D6HE-II.

D16HE and D16HE-II are Sino-Telecom Technology's 200G/400G stackable wavelength division transmission platforms. They feature ultra-large transmission capacity, compact size, low power consumption, and convenient operation. They offer strong scalability, high reliability, and security for connections, making them widely applicable in data center interconnection and new urban area network transmission. Built on an open software architecture, they provide various open interfaces for easy integration into third-party comprehensive network management systems. 

Final Achievement 

By applying DCI technology, we established an advanced urban area network transmission system for the client. This transmission system injects new vitality into the city's information flow, driving urban development and innovation. Whether it's transmitting large-scale data or meeting latency and bandwidth requirements, we can satisfy the client's needs, providing robust support for the city's information exchange.

This case not only showcases the progress of DCI technology but also highlights people's pursuit of efficient and reliable transmission.

Looking Ahead

The emergence of continuous internet services and the rapid evolution of cloud computing have propelled the flourishing development of DCI networks over the past decade. 

In the foreseeable future, 5G networks, the Internet of Things (IoT), Augmented Reality (AR), Virtual Reality (VR), and edge cloud computing will continue to drive the rapid growth of DCI networks. An open DCI ecosystem will be more conducive to the development and introduction of new technologies, promoting technological innovation and industry prosperity, better meeting the needs of customers and businesses.
