Viavi Fiber Sensing
Insatiable data demand, caused by the relentless growth of mobile and Internet of Things (IoT) devices, is driving mobile networks to evolve from a typical macro cell site based coverage topology to a denser capacity-based heterogeneous network. Recent advancements in radio technology (improved power amplifier efficiency, better design and longer MTBF), have enabled service providers to install remote radio units (RRU or RRH) close to the antenna near the top of the tower. This technology improvement has enabled service providers to improve capacity, coverage, and signal integrity, while at the same time reduce electrical, leasing, and cable costs.
Viavi helps ensure top performance in virtually every major network—from the NOC to field technicians—and over 100,000 data centers worldwide, from deployment and installation to monitoring and optimization.
FTH-DTS
The Fiber Test Head for Distributed Temperature Sensing (FTH-DTS), part of the NITRO Fiber Sensing solution, provides continuous monitoring of fibers cables and fiber-enabled assets. Utilizing fiber optic cables to provide continuous and real-time information about temperature in and around your assets, with immediate detection and localization.
Designed for industries that demand high precision and reliability, our innovative technology delivers Distributed Temperature Sensing (DTS) for absolute measurements of temperature along extensive lengths of fiber optic cable, making it an indispensable tool for numerous applications.
Capable of detecting anomalies in diverse applications such as critical infrastructure (power utilities), pipelines (oil, gas, water, etc.), telecom networks (Data Center Interconnects – DCI) and beyond.
Proactive monitoring tracks changes in temperature, information which can be used to improve operational efficiency and responsiveness and allow for preemptive/proactive actions to be taken to mitigate potential damage or outages.
Giving you high confidence by ensuring optimal asset performance from day 1.
Also available as a portable solution (OneAdvisor 800 DTS) for routine site audit, spot checks and troubleshooting.
