This paper considers a short packet transmission scheme based on optical fiber sensing technology, which consists of a transmitter and K users. Considering that the error probability in short packet communication cannot be ignored, we first derive the expression of the block error probability of the receiver based on the approximation of the Gaussian function, then the delay boundary is analyzed based on stochastic network calculus, and the delay violation probability under the target delay constraint is finally obtained. According to the simulation results, it can be concluded that the block error probability of the receiver can be reduced by increasing the number of launchers and the length of the data packet, thereby improving the reliability of the short packet transmission system based on optical fiber sensing technology. In addition, by increasing the threshold of block error probability, increasing the information transmission rate and the accumulated departure of the system can be improved, and the waiting time of arriving data packets will be reduced, thereby improving the delay performance of the short packet transmission system based on optical fiber sensing technology.
