From September 11 to 13, 2024, at the 25th China Optical Expo CIOE2024, Huagong Zhengyuan’s industry first launched the new energy vehicle “optical fiber on-on-board plan”. The latest on-board optical network controller OCU is a vehicle-level optical fiber backbone network for the next generation of new energy vehicle E/E architecture. The core control unit for the solution.
Optical fiber “get on the car” to enjoy high-speed vehicle networking
It has become the consensus in the industry that new energy vehicles become super intelligent mobile terminals. The in-vehicle communication network is moving from a distributed architecture to a domain-centralized electronic and electrical architecture. High-bandwidth, low-latency and high-reliability network communication architecture technology has become a new demand for in-vehicle network communication.
The industry is developing the 802.3cz (released in early 2023) standard based on IEEE, introducing optical fiber as the transmission medium, with a transmission bandwidth of up to 50Gbps, and the optical fiber itself has the advantages of high bandwidth, high resistance to electromagnetic interference, low loss, light quality and so on.
The in-vehicle optical network controller OCU pioneered by Huagong Zhengyuan is a new solution to introduce optical fiber into the car and solve the lightweighting of automobile wiring harnesses, which will promote the iterative upgrading of automotive electrical architecture in the future.
Highlights of the new product scheme of on-board optical network controller OCU:
The on-board optical network controller OCU is rich in functions, powerful in performance, safe and reliable. In the on-board network, it can not only complete high-time, high-speed and high-security transmission and communication functions, but also customize the regional vehicle control-related functions according to the car model in the regional subnet. At the same time, the unique self-grouping network function can be in different forms. Flexible deployment in the E/E architecture to meet the diversified needs of network topology.
OCU has the functions of regional control and backbone network communication:
High-speed transmission: real-time transmission of data from optical fiber, T1 Ethernet, video and other interfaces;
TSN gateway: ensure real-time data transmission on optical fiber and T1 Ethernet;
QoS guarantee: data flow classification, scheduling and priority processing, etc., to ensure the real-time and user experience of the business;
Link protection: When the optical link or T1 link fails, switch to the backup link immediately and continuously stream;
Equipment management: traffic and link status monitoring, end-to-end fault alarm, mitigation strategy execution and other functions;
Security authentication: ensure the security of network data transmission through identity authentication;
Regional control: regional gateway, intelligent power distribution, network management, power management, diagnosis, etc.;
Extended functions: customize regional application functions according to customer needs, such as BCM, etc.
PNA Fiber has taken the lead in promoting this program to foreign markets. If you are interested, please feel free to contact us.
