The GPON government and enterprise network solution has been implemented, creating a "low-latency and highly reliable" network for large manufacturing enterprises

In response to the high demands of government and enterprise customers for network stability and security, the Passive Optical Network technology team has recently launched a customized GPON government and enterprise network solution. This solution, with its core advantages of "low latency transmission", "multi-service integration", and "secure isolation", has been successfully applied in the intelligent factory construction of a large automotive manufacturing enterprise. Help enterprises achieve real-time transmission of production data and collaborative control of equipment. ​

In terms of technical design, this GPON solution adopts a "layered networking architecture" : The core layer is redundantly deployed through dual OLT devices to ensure that a single point of failure does not affect the overall network. The access layer connects the PLC equipment, industrial cameras, AGV robots and other terminals in the production workshop to the network through GPON optical splitters. The optical splitter ratio supports flexible configuration from 1:8 to 1:32, adapting to the terminal density requirements of different workshops. To meet the low latency requirements of industrial scenarios, the solution optimizes the GPON protocol stack, controlling the data transmission latency within 10ms, which is 60% lower than that of traditional Ethernet, ensuring the real-time navigation of AGV robots and the synchronous control between devices. ​

The multi-business integration capability is another major highlight of this solution. In addition to the transmission of production data, the solution can also simultaneously carry enterprise video surveillance, voice communication, office network and other services. Through VLAN division and QoS priority setting, it ensures the priority transmission of production data and avoids the interference of office traffic to the production network. In the application of a certain automotive manufacturing enterprise, this solution has enabled real-time transmission of 4K industrial cameras in the body welding workshop. The video transmission frame rate is stable at 30fps, with no lag or packet loss. Meanwhile, by integrating with the enterprise ERP system, production data can be synchronized to the management platform in real time, with a 100% visualization rate of production progress and a 15% reduction in the order delivery cycle. ​

In terms of security, the solution supports AES-256 encrypted transmission and 802.1X authentication to prevent data from being stolen or tampered with during transmission. Meanwhile, the OLT device is equipped with port isolation function, which can completely isolate the networks of different workshops and prevent the spread of network faults in a single workshop. The IT director of the automotive manufacturing enterprise stated: "The GPON solution not only meets our requirements for low latency and high reliability of the network, but also realizes the unified carrying of multiple services, reduces the cost of network construction and maintenance, and provides key support for the digital transformation of smart factories."

At present, this GPON government and enterprise network solution has been expanded to fields such as power, energy, and finance, serving over 500 government and enterprise customers. In the future, it will also launch more customized solutions tailored to the specific needs of different industries.
