Guangdong Telecom partners with Huawei to build the first 400G all-optical network in the Greater Bay Area

Recently, China Telecom Guangdong and Huawei jointly built the first 400G all-optical capacity network in the Guangdong-Hong Kong-Macao Greater Bay Area, deploying advanced all-optical cross-OXC, ultra-high-speed 400G, automatic switched optical network ASON, iMaster NCE and other solutions to provide high-quality transportation capacity of ultra-low latency, ultra-large bandwidth, ultra-high reliability, super intelligence, green and low-carbon for Shaoguan, Guangzhou and Shenzhen, and help the super computing power of the national hub Shaoguan cluster radiate to the Greater Bay Area, realizing "business development by calculation" and supporting the high-quality development of the digital economy in the Bay Area.

The network can realize the deep integration of the powerful computing power of the Shaoguan cluster with the digital industry of the Greater Bay Area, and realize the high-quality transportation capacity to connect the computing power supply side and the demand side, so that the computing power can be transmitted unimpeded to enterprise users, so that users are as convenient as electricity, so that the computing power is within reach, "computing" can be used to its fullest extent, and thousands of industries can be empowered. According to reports, Guangdong Telecom has created an ultra-low latency circle covering the Guangdong-Hong Kong-Macao Greater Bay Area and South China through the ROADM architecture of the integration of one and two branches, coupled with advanced all-optical cross-OXC, which can quickly connect multiple provinces (regions and cities), so that the computing power can be "instantaneously reachable". When a fiber failure occurs, the network can automatically find a recovery path, and the business availability rate exceeds 99.999%, so that the computing power service "never interrupts" At the same time, with single-wave 400G technology, single-fiber capacity can reach a maximum of 48Tbps, further reducing single-bit costs, enabling the smooth transmission of massive data between enterprises and computing power centers.

As one of the eight computing power hubs in the national "Eastern Digital and Western Computing" project, the Shaoguan cluster will undertake the real-time computing power needs of core cities in the Greater Bay Area such as Guangzhou and Shenzhen, and build a computing power center that radiates to South China and even the whole country. It is expected that by 2025, the Shaoguan cluster can be built into a world-class computing power facility cluster. Based on the high-quality all-optical capacity network, Guangdong Telecom can provide high-quality computing power services for thousands of industries and greatly improve the user experience. For example, after the online cloud VR education is rendered in the cloud, it can be quickly transmitted to the end user with a millisecond-level delay circle, effectively avoiding the appearance of user vertigo; in scenarios such as "East Digital Storage" and "East Digital West Training", tens of terabytes of massive data can be quickly transmitted to the hub cluster relying on super-large bandwidth; smart factories can achieve ultra-reliable 7 × 24-hour "zero-interruption" connection with the industrial cloud to meet the demands of scenarios such as cloud quality inspection and flexible manufacturing.

The era of computing power has come. Guangdong Telecom, adhering to the concept of innovation-driven development, took the lead in deploying the first 400G all-optical capacity network in the Bay Area, relying on a strong all-optical base to provide ubiquitous high-quality capacity, and helped the Shaoguan cluster become a real-time computing power center radiating to the Bay Area, South China and even the whole country. In the future, Guangdong Telecom will continue to provide network services with the ultimate experience for enterprises in the Guangdong-Hong Kong-Macao Greater Bay Area, and promote the digital transformation and upgrading of industries such as industry, agriculture, and service industries.
