OptaSense - Model ODH4+ -Distributed Acoustic Sensing Interrogator
The ODH4+ Distributed Acoustic Sensing Interrogator from Luna Innovations is a high-performance instrument designed for improved fiber optic sensing. This device delivers an enhanced signal-to-noise ratio while offering variable spatial resolution, which allows for refined measurement accuracy across a variety of applications. The system`s upgraded sensitivity and performance features make it a suitable choice for advanced distributed sensing requirements. The technology underpins the monitoring of acoustic signals over extended fiber optic networks, providing precise data used in sectors such as energy, infrastructure, and security. The improvements in the ODH4+ focus on achieving greater sensing accuracy and reliability, essential for analyzing complex environmental and structural conditions.
The ODH4+ IU provides value to both engineering and geoscience applications which require variable spatial resolution. Unlike conventional interrogator units , the ODH4+ IU is capable of measuring with ANY fiber from ANY vendor (single mode, multi-mode or enhanced high backscatter) for superior signal-to-noise ratio levels. With the ability to provide variable spatial resolution regardless of the glass present in the cable, operators are no longer limited to a specific fiber dedicated to single measurement, expanding the possibilities for sensing any physical process.
When combined with high backscatter fiber, the ODH4+ unit delivers a level of enhanced distributed acoustic sensing sensitivity capable of responding to the smaller signals associated to more subtle changes in the reservoir like those associated with the hydraulic fracturing processes.
The ODH4+ IU utilizes a key redesign of OptaSense’s leading-edge interrogator unit technology specifically designed to take advantage of the availability of new enhanced fiber-optic technology for specialized applications and signal requirements. The new IU design delivers superior performance, generating cleaner and stronger signals on a variety of fibers.
The ODH-4+ offers several enhancements to our current interrogator unit technology, including more robust laser controls optimizing the highest signal fidelity. With the variety of fiber-optic cables now available in the market, the ODH4+ system provides the flexibility to interrogate various fibers without compromising the measurements and without incurring additional hardware costs specific to these given fibers.
