It aims to create a smooth and unimpeded "light" information channel for the future intelligent transportation business such as real-time vehicle identification, etc automatic charging, vehicle road coordination, etc. on the expressway, to ensure the transmission safety of traffic production data, and better serve the safe and convenient travel of the majority of car owners. It is planned to install etc stations on high-speed trunk lines all over Guangdong, and establish real-time communication between etc stations and data centers through backbone network. At the same time, the network must also be able to support the unified bearing and independent operation of various services of the highway, and improve the level of security. So we need three key values:
1. 100g ultra long distance transmission, to create a smooth and unimpeded "optical" high speed: 7Nm self-developed odsp chip, to achieve the industry-leading 100g ultra long distance transmission capacity; lower power consumption, lower delay, to ensure vehicle road cooperation.
2. Industrial level security guarantees the transportation and production data transmission: physical isolation, optical layer encryption, data security; ASON (automatic switching optical network) is resistant to multiple optical fiber cutting failures, with a reliability of 99.999%.
3. Support the unified bearing of various businesses of Expressway and improve the efficiency of network operation and maintenance: the original unified bearing technology of hard and soft pipelines, without mutual interference. Hard pipeline (WDM) carries high priority services such as charging and voice services; soft pipeline (Ethernet) carries office, video monitoring, bandwidth sharing, and improves bandwidth utilization.
