7 terms

distributed acoustic sensing technical

"launch of a new next-generation fiber test head for distributed acoustic sensing (FTH-DAS)"

Distributed acoustic sensing is a monitoring technology that turns a long fiber-optic cable into a continuous network of vibration sensors by sending laser pulses down the cable and reading tiny changes in the returning light when the ground or structures vibrate. For investors, it matters because it provides real-time, wide-area detection of leaks, pipeline damage, construction activity, earthquakes or drilling events—like turning a fence into a string of motion detectors—helping firms reduce risk, cut inspection costs and protect assets.

true-phase das interrogator technical

"The FTH-DAS is a true-phase DAS interrogator with embedded AI and machine learning"

A true-phase DAS interrogator is a fiber‑optic sensor unit that detects tiny mechanical disturbances along a long optical cable by tracking subtle shifts in the light’s timing and waveform, producing a continuous, location-specific map of vibrations and strain. Investors care because it enables high‑precision, low‑maintenance monitoring for pipelines, railways, borders and infrastructure, cutting false alarms and service costs while creating recurring revenue opportunities—like turning one wire into thousands of motion sensors.

ai/ml technical

"true-phase DAS interrogator with embedded AI and machine learning (ML) engine"

AI/ML stands for artificial intelligence and machine learning, software systems that identify patterns in data and make predictions or automate decisions, improving performance as they process more information. Investors care because these technologies can boost revenue, cut costs and create competitive advantages — like a factory that learns to produce goods faster and with fewer mistakes — while also introducing execution, ethical and regulatory risks that can affect a company’s value.

otdr technical

"Classic OTDR, temperature, strain and acoustic monitoring is now possible"

An OTDR (Optical Time-Domain Reflectometer) is a handheld or rack-mounted instrument that tests fiber-optic cables by sending light pulses down the cable and measuring reflections to map length, signal loss, and faults—think of it as an ultrasound or sonar for fiber networks. For investors, OTDR use signals the health and maintainability of telecommunications infrastructure, affecting capital spending, service reliability, repair costs and the pace of network expansion.

rayleigh backscatter technical

"technique to recover the optical phase from Rayleigh backscatter."

Rayleigh backscatter is the tiny amount of light that bounces back toward its source when a light wave hits very small imperfections or molecules in an optical fiber or the atmosphere. For investors, it matters because it both limits how far and how cleanly optical signals can travel—affecting telecom and sensor performance—and provides a way to monitor fiber health and detect problems along a cable much like listening for echoes to find a leak in a pipe.

phase-stepping interferometry technical

"adopts a VIAVI-patented phase-stepping interferometry technique to recover the optical phase"

Phase-stepping interferometry is an optical measurement technique that maps tiny variations in surface shape or thickness by recording multiple light interference patterns while shifting the relative phase in small steps. For investors, it signals a company’s ability to perform extremely precise quality control or research in fields like optics, semiconductors, and photonics—analogous to taking several slightly offset, high-resolution photos to reveal microscopic bumps and flaws that a single picture would miss.

fiber sensing technical

"new next-generation fiber test head for distributed acoustic sensing (FTH-DAS) to enhance their NITRO™ Fiber Sensing solution"

Fiber sensing uses thin strands of glass or plastic (optical fibers) as long, distributed sensors that detect changes in temperature, strain, vibration or sound along their length by measuring how light traveling through them is altered. For investors, it matters because these sensors can turn existing infrastructure—pipelines, railways, bridges, power lines—into continuous monitoring systems that lower maintenance costs, improve safety, and create recurring revenue opportunities for companies that make, install or analyze the sensor data; think of it as turning a fiber-optic cable into a string of smart, remote thermometers and motion detectors.

System implements patented phase-based DAS techniques to deliver the highest fidelity data and actionable information

CHANDLER, Ariz., March 10, 2026 /PRNewswire/ -- VIAVI Solutions Inc. (VIAVI) (NASDAQ: VIAV) has announced the launch of a new next-generation fiber test head for distributed acoustic sensing (FTH-DAS) to enhance their NITRO™ Fiber Sensing solution. The FTH-DAS is a true-phase DAS interrogator with embedded AI and machine learning (ML) engine. Designed for the network edge, the FTH-DAS interrogator enables multi-event detection and localization with real-time event classification across multiple fibers directly on the device.

"By combining on-device Machine Learning alongside a patented true-phase DAS technique, the VIAVI FTH-DAS delivers the enhanced measurement accuracy and interpretation needed for real-time intelligence," said Kevin Oliver, Vice President and General Manager, Fiber and Access Solutions, VIAVI. "To put this into context, a gas pipeline operator would not only be able to detect leaks, but also nearby digging, vehicles and even footsteps, with the AI allowing for instantaneous and true alerts to prevent accidental damage before it happens. Classic OTDR, temperature, strain and acoustic monitoring is now possible in a single fiber core for both dark and in-service fiber links."

DAS fiber sensing uses traditional optical fibers as a continuous microphone to detect and locate damage and potential threats over long distances. The number of applications for DAS technology has risen significantly in recent years, and now includes threat identification for data centers and telecom network cables, security surveillance of borders and sensitive perimeters, as well as monitoring of critical infrastructure ranging from identifying pipeline leaks to detecting undersea power cable wear.

VIAVI's AI/ML event detection and classification models have been developed based on decades of historical data. The tools and models are run and automatically updated at the edge on the FTH-DAS without the need for external, remote and centralized processing or manual intervention. The AI/ML engine analyzes data in real time from the fiber links under test, allowing minimal commissioning time while enhancing event identification, classification and tracking over time. Continuous, scalable model adaptation is implemented for automatic improvement in a private or VIAVI-managed cloud-based ecosystem.

The true-phase DAS adopts a VIAVI-patented phase-stepping interferometry technique to recover the optical phase from Rayleigh backscatter. Beyond just detecting disturbances, this approach allows for true measurements of physical quantities such as strain, vibration amplitude, frequency and true acoustic power. Results are repeatable, objective and comparable across deployments, enabling applications beyond simple event detection and allowing robust ML training and inference.
