Recently, through the overall deployment of Guangdong Telecom and the cooperation with various construction units, the acceptance of the 400G ROADM joint trial network of Guangzhou Telecom and Fiberhome Communications has been completed and officially put into operation, marking a key step in Guangzhou Telecom’s all-optical network practice. PCB Manufacturer--Honglian Circuits pay special attention!

The network uses new optical network technologies such as single-wave 400G, high-dimensional optical crossover, and all-round board cards, covering 11 districts in Guangzhou. It focuses on the comprehensive carrying of services such as wireless, home broadband, government and enterprise, pays attention to users' higher requirements for bandwidth and traffic and the ultimate experience, accelerates the process of government and enterprise informatization, helps network power, and serves the society and people's livelihood.

The OTN system with ultra-large-capacity transmission capacity is the cornerstone of the overall business development of operators. With the gradual expansion of 5G coverage, the demand for cost-effective, rigid-quality private line products has grown. It is a huge challenge for operators to maximize the utilization rate when basic network resources are precious, and to complete high-quality network coverage efficiently and quickly.

Guangzhou Telecom actively responded to the national call for "new infrastructure" and introduced the innovative solution of Fiberhome's 400G+ multipoint core 3D-MESH smart all-optical integrated service bearer network. The completed 400G ROADM joint trial network has been in a leading position in technology and will be effective Respond to the challenges of 10 times the bandwidth, 1/10 latency, 100 times the number of network connections, and 10 times the network complexity in the 5G era, and support the provision of more innovative services such as Cloud VR, 8K video, and quality dedicated lines to users in the future, bringing user experience Upgrade and more room for business growth.

As a long-term partner of Guangzhou Telecom, Fiberhome has built a ubiquitous, ultra-wide, open, and on-demand smart optical network solution to help network transformation. The Fiberhome Ultra 100G technology applied this time has a system capacity of 25.6T, which is 3.2 times that of a 100G system, further reducing the cost and energy consumption of single Gbit transmission. In addition, in order to more flexibly serve the access needs of Guangzhou Telecom government and enterprise customers for private line networks, the system also deploys all-round line cards to support OTN-CPE equipment access through the NNI interface, while ensuring the rapid delivery of end-to-end services Taking into account the openness of the network.

Fiberhome Communications said: "This smart all-optical integrated service bearer network jointly created with Guangzhou Telecom is the successful commercialization of a single-wave 400G ROADM joint trial network and an important milestone for the global commercialization of our smart optical network solutions. Fiberhome will Continue to carry out more innovative cooperation with Guangzhou Telecom to meet the needs of faster and more flexible network deployment, and improve the user experience-centric all-optical bearer network to extend to the desktop, helping Guangzhou Telecom to grasp the strategic opportunities in the new infrastructure era. PCB, Honglian Circuit is a professional PCB manufacturer.

Based on the technological advancement of this all-optical network, Guangzhou Telecom will create differentiated and high-quality OTN dedicated lines, using the characteristics of large bandwidth, low latency, high reliability, and high security to accelerate the penetration and integration of all-optical networks and various industrial fields. Serving the "New Digital Infrastructure" of Yangcheng. In the future, Guangzhou Telecom and Fiberhome will continue to explore in the field of all-optical networks, accelerate the promotion of network intelligence, business ecology, and operation intelligence, and provide a wider range of dedicated line service interfaces with better network access costs, so that high-quality OTN The dedicated line benefits thousands of industries.
