Recently, China Unicom Chongqing announced the successful completion of the world’s first trial commercial use of “Alps-WDM+OSU”.
China Unicom Chongqing and Huawei Complete the World’s First Trial Commercial Use of “Alps-WDM+OSU”
The innovative Alps-WDM technology is reported to have improved network capabilities and customer experience in the following aspects:
- Improved bandwidth supply capabilities: The bandwidth of integrated access sites increases 10 Gbit/s to 100 Gbit/s. Multiple areas share the bandwidth resource pool, and resources can be obtained on demand.
- Lower network latency and improved flexible grooming capabilities: One-hop transmission at the optical layer and flexible grooming at the electrical layer reduce E2E latency to milliseconds.
- Optimized O&M efficiency, accelerating response to market demands: The Digital Optical Label technology enables one-click automatic planning, deployment, and maintenance for quick responses to customer requirements.
- Green and low-carbon development: Through architecture and technological innovation, Alps-WDM improves the site integration of integrated access equipment rooms and reduces both footprint and power consumption by more than 50%. This helps to better support the green, low-carbon, and high-quality development of China Unicom Chongqing.
This trial commercial use of Alps-WDM has also integrated the OSU technology. The test results show that “Alps-WDM+OSU” supports flexible pipe resource scheduling, lower node latency, and intelligent management and control, thereby reducing costs and improving network service quality. The successful application of “Alps-WDM+OSU” technology enables All-Optical Transport Networks to provide higher-quality services for more industry users. In the future, China Unicom Chongqing will use ROADM+OTN as the all-optical transport capacity foundation to connect to enterprises, homes, and other scenarios. With “Alps-WDM+OSU”, resources can be obtained on demand and made available with one click to facilitate the development of four premium networks, providing better services for various industries and homes and promoting digital construction.
 Four premium networks refers to China Unicom’s solutions published on 2022: the premium 5G network, premium broadband network, premium enterprise network, and premium computing power network
