Comparison of J1939 to Open End Tail Fiber Cable with CAN Bus and Other Protocols

The characteristics and advantages of J1939 to open end tail fiber cable compared to CAN bus and other communication protocols.

Compared with CAN bus, J1939 is an application layer protocol developed based on CAN 2.0 protocol, which adds network layer, application layer, and network management specifications on the basis of CAN. J1939 defines detailed PGN and SPN, achieving compatibility and standardized communication between devices from different manufacturers. The CAN bus mainly provides services at the physical layer and data link layer, with relatively few specifications at the application layer. The J1939 to open end tail fiber cable combines the advantages of J1939 in vehicle internal communication with the long-distance and high-speed advantages of fiber optic communication, and can meet more complex communication needs.

Compared with other communication protocols such as LIN bus, LIN bus is a low-cost serial communication protocol mainly used for low-speed sensor and actuator communication in automobiles, with a lower transmission rate, usually below 20Kbps. The J1939 to open end tail fiber cable is suitable for high-speed and real-time communication scenarios, and can meet the communication requirements of complex electronic systems in vehicles.

Compared with Ethernet protocol, Ethernet has high bandwidth and good scalability, but in terms of real-time and reliability, J1939 protocol has more advantages in the automotive field. The J1939 to open end tail fiber cable has been optimized for automotive application scenarios, which can better meet the strict requirements of vehicles for real-time communication and reliability, and provide stable and reliable communication support for automotive electronic systems.
