FIBER SENSING SYSTEM, RELAYING APPARATUS, AND FIBER SENSING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18484894 titled 'FIBER SENSING SYSTEM, RELAYING APPARATUS, AND FIBER SENSING METHOD
Simplified Explanation
The present disclosure describes a fiber sensing system that includes a submarine cable and multiple relaying apparatuses connected in series via the cable. Each relaying apparatus consists of a DAS interrogator connected to a subsequent apparatus through a sensing optical fiber, and a terminator connected to a preceding apparatus via the same fiber. The DAS interrogator emits probe light into the sensing optical fiber, while the terminator terminates the probe light from the DAS interrogator in the preceding apparatus. The DAS interrogator then receives backscattered light of the probe light from the fiber and extracts DAS data from it.
- The fiber sensing system includes a submarine cable and multiple relaying apparatuses connected in series.
- Each relaying apparatus comprises a DAS interrogator, a sensing optical fiber, and a terminator.

Possible Prior Art
One possible prior art is the use of distributed acoustic sensing (DAS) technology in fiber optic sensing systems for structural health monitoring in civil engineering applications.
What are the limitations of the current fiber sensing system described in the patent application?
The current system may have limitations in terms of:
- Distance over which the sensing optical fiber can effectively transmit data
- Sensitivity to external factors that could affect the accuracy of the measurements
How does the fiber sensing system compare to traditional monitoring methods in terms of cost-effectiveness?

Original Abstract Submitted
A fiber sensing system according to the present disclosure includes a submarine cable, and a plurality of relaying apparatuses being connected in series to one another via the submarine cable. The relaying apparatus includes a DAS interrogator being connected to a relaying apparatus at a subsequent stage via a sensing optical fiber in the submarine cable, and a terminator being connected to a relaying apparatus at a preceding stage via the sensing optical fiber. The DAS interrogator outputs probe light to the sensing optical fiber. The terminator terminates probe light being output from the DAS interrogator in the relaying apparatus at the preceding stage to the sensing optical fiber. The DAS interrogator receives backscattered light of probe light from the sensing optical fiber, and acquires the DAS data from the received backscattered light.
