FiberSense EVP Shines a Light on the Latest in Subsea Cable Monitoring Technologies in ISE and SubTel Forum Magazine Pieces

There is a growing trend of thought leadership recognition for FiberSense that is continuing momentum into 2023.

Rajiv Jayawardena, executive vice president of business development and transformation at FiberSense, wrote two separate thought leadership pieces on fiber sensing technology in both Submarine Telecoms Forum Magazine and ISE Magazine in January.

In a Jan. 11 ISE story titled “Seeing Under the Sea in 2023,” Jayawardena writes that improved technologies exist today to protect subsea cable on seabed floors for years to come, including Vibration Detection and Ranging (VID+R) technology. 

With approximately 800,000 miles of cable underneath the water, connecting us from continent to continent through more than 500 active submarine cables, Jayawardena makes the case for VID+R technology as a solution to protect these critical assets.

“Even with some protection in place, unexpected strikes on subsea cables have always posed a risk. One new technology that can help is a passive sensor system delivered over optical fiber cable infrastructure called Vibration Detection and Ranging (VID+R). This technology is pulled together into a digital platform that triggers an alarm when the ground is disturbed around live cables, proving an early warning,” Jayawardena writes in the ISE piece.

Submarine Telecoms Forum Magazine published an article written by Jayawardena in its January 2023 “Data Centers & New Technologies” edition in a story titled “The Evolution of Cable Network Monitoring and Sensing,” located on pages 88-90 of the January 2023 magazine. The story focuses on sensing-as-a-service and its future use in revolutionizing early warning systems for seismic activity and tsunamis. 

“Alternative forms of earthquake and tsunami early warning systems are uneconomical in the oceans, due to the high cost of sensors, underwater housings, data telemetry, and operations and maintenance. Earthquake sensing with fiber-optics offshore and onshore can provide actual quantitative event magnitude estimates, real-time estimates of the number of seconds of early warning time to populated areas, and rapid peak ground acceleration maps by addressing after the shaking for first responders to prioritize the hardest hit building. Tsunami wave detection is also possible,” Jayawardena writes in the Subtel piece.

Jayawardena brings more than 20 years of experience and leadership in the telecommunications industry to his role at FiberSense, where he continues to develop and promote the company’s fiber sensing technology products

FiberSense services monitor underground assets and have been activated across fiber networks in Europe, the Americas, Australia and across subsea cables linking major continents. 

Just last month, FiberSense Vice President of Science and Innovation Nate Lindsey received recogition in The Atlantic for his fiber optic technology expertise.
