System integration and delivery
| Mode | Deliverables and use |
|---|---|
| Complete instrument | DAS instrument and software for end-user projects |
| Modules | Optical, acquisition and processing modules for integration into customer enclosures |
| OEM | Adaptation of enclosure, markings, interfaces and configuration |
| ODM | Project-specific mechanical, interface, functional and software design |
| Software integration | Agreed data and phase protocols for AI and third-party platforms |
| Application integration | Combined configuration of sensing cable, DAS, AI and application platforms |
Signal path: sensing fiber → DAS core module → Gigabit Ethernet and data protocol → server/edge computing → application platform. Standard single-mode fiber is used; configure peripherals, cable and protocols for the project.
Agree interface access, version management, integration drawings, software functions and support in the supply configuration. Validate third-party software and algorithms in the integrated system.
Frequency range depends on fiber length, scan rate, gauge length and SNR. The 100 kHz upper limit applies only to short-range configurations with adequate high-speed sampling, not simultaneously across a 30–100 km fiber. Conventional per-point temporal sampling must satisfy the Nyquist criterion with anti-aliasing margin.
