OBD2 16 pin to open end tail fiber cable: Bridge technology for automotive diagnostics

The OBD2 16 pin to open end tail fiber cable is a key component in the field of automotive electronic diagnostics, and its core function is to achieve seamless integration between standard OBD2 interfaces and customized tail fiber systems. Taking a certain brand of truck diagnostic system as an example, the cable is connected to the vehicle ECU through a 16 pin OBD2 female head, and the other end adopts an open end tail fiber design, supporting fiber optic sensors or high-frequency signal transmission.

On a technical level, the cable needs to be compatible with SAE J1939 protocol and CAN bus standards. For example, in diesel engine emission monitoring, pin 2 (positive terminal of the bus) and pin 10 (negative terminal of the bus) form a power supply circuit, while pin 7 (K-wire) is responsible for transmitting control commands between the ECU and the diagnostic instrument. The tail fiber at the open end is made of low loss fiber material, supporting high transmission rates.

In practical applications, a logistics company deployed such cables to extend the on-board OBD2 interface to the top of the cab, and combined it with fiber optic exhaust sensors to achieve remote real-time monitoring. The data shows that this solution shortens the fault response time and reduces the annual maintenance cost.
