Based on research that concludes the commercial viability of distributed acoustic sensing in conduit, the sensing industry can enjoy the same robust conduit pathway benefits and advantages with highly sensitive commercial DAS implementation.
Built upon the industry’s leading interrogator unity technology, OptaSense is excited to introduce the latest in our cutting-edge portfolio of interrogator units, the ODH4+. Unlike conventional interrogators , the ODH4+ IU is capable of measuring with ANY fiber from ANY vendor
“The RT80 trencher was built to adapt,” said Chris Thompson, Ditch Witch product manager, heavy-duty trenchers. “Faced with tighter deadlines, smaller budgets and more congested underground networks, contractors need a utility trencher that can fit and function in any environment.
Researchers are studying ways to use existing fiber-optic cables as distributed sensors to collect data on city road conditions. Verizon and NEC recently conducted a proof-of-concept field trial
Observing this "backscatter" phenomenon through a technique called Distributed Acoustic Sensing (DAS), the 20 km long cable was turned into a bed of 10,000 motion sensors that could detect seismic activity with picometer precision.
