As the demand for resilient, intelligent, and perceptual optical infrastructure continues to grow, fiber sensing and in-service network tomography are emerging as a promising path toward achieving comprehensive visibility—not only of the fiber network itself, but also of the physical environments it traverses. Fiber sensing technologies have demonstrated the ability to detect seismic activity, temperature variations, and acoustic signals over long distances, enabling possibilities for dual-purpose infrastructure that supports both high-speed data transmission and real-time environmental monitoring. At the same time, coherent-DSP-based link tomography is redefining how we observe and manage in-service fiber networks, offering new means for monitoring distributed link parameters, diagnosing performance of networks, detecting localized impairments—all without deploying intrusive hardware.
While both fiber sensing and link tomography have demonstrated impressive capabilities in field trials and demos, the question remains: are they ready to meet the demands of real, heterogeneous, and large-scale networks? This workshop will explore the technical maturity, practical feasibility, and deployment potential of fiber sensing and tomography technologies and assess whether these advanced monitoring techniques are academic curiosities or true game-changers in the way we use optical networks.
The key questions to address in this workshop are:
- What are the current limitations and readiness levels of fiber sensing and tomography technologies for real-world deployment?
- Can fiber sensing and tomography provide actionable insights and use cases for network operators?
- In what ways does tomography complement or overlap with traditional monitoring systems such as OTDR or optical channel monitor (OCM)?
- How are early signs of standardization, commercialization, or network integration beginning to emerge?
