Solution Overview
Problem
The existing optical fiber sensing systems require a complex configuration with a data line between the host station and the remote station for data communication, making it difficult to construct and maintain an efficient sensing system.
Innovation Solution
The system includes a host sensing device and a remote sensing device, each equipped with optical sensing means and data communication means, allowing for the transmission of sensing data and signal light between the two devices via a single optical fiber, eliminating the need for a separate data line for data communication between the analysis device and the remote station.

1Reliability
If a separate data line is installed between the host station and the remote station for data communication, then reliable data transfer is achieved, but the system configuration becomes complex and construction becomes difficult
Solution Approach 1:
The patent combines the sensing data transmission function and the communication data transmission function into a single optical fiber. The remote station sends both sensing results and communication data through the same optical fiber to the host station, eliminating the need for separate data lines and simplifying the overall system configuration while maintaining reliable data transfer
Solution Approach 2:
The optical fiber is designed to serve multiple functions: it acts as both the sensing medium (for transmitting pulse light and receiving backscattered light) and the communication channel (for transmitting sensing data and communication data). This multi-functionality reduces the number of components needed and simplifies the system architecture
