Description:
Subsea fibre optic cables face growing security threats, driving demand for
advanced monitoring solutions.
FULL STORY
======================================================================
- Distributed acoustic sensing detects disturbances in fibre optic signals
to identify underwater threats
- NATOs Baltic Sentry mission enhances subsea security, but surveillance
remains difficult
- AP Sensings North Sea deployment highlights fibre optics role in security
Subsea fibre optic cables are a crucial part of global internet
infrastructure, yet recent damage incidents in the Baltic Sea have raised
concerns about their security.
Per the BBC , there are now efforts to mitigate the risk of sabotage by using
a decades-old technique known as distributed acoustic sensing (DAS).
This approach detects disturbances in fibre optic signals by capturing tiny
reflections sent back along the strands due to pulses from light encountering
vibrations or temperature changes, allowing the system to identify suspicious
activity such as underwater drones, vessels dragging anchors, or divers near
critical cables.
How fibre optics can `listen` for threats
As with network security, where businesses rely on the best small business
routers to prevent cyber threats, monitoring solutions for subsea
infrastructure are becoming essential in safeguarding global communications.
Lane Burdette, a research analyst at TeleGeography, notes that the number of
faults affecting subsea cables each year has remained steady, typically
between 1 and 200. "Cables break all the timeThe number of cable faults per
year has really held steady over the last several years."
During tests conducted by AP Sensing, the system detected a diver patting a
cable on the seabed, while further experiments demonstrated its ability to
identify drones and vessels, potentially providing early warnings of sabotage
attempts.
"He stops and just touches the cable lightly, you clearly see the
signal...The acoustic energy which travels through the fibre is basically
disturbing our signal. We can measure this disturbance," says Daniel Gerwig,
global sales manager at AP Sensing, a German technology company.
Just as businesses depend on the best business smartphones for real-time
alerts and security updates, early warning systems for subsea cables can
provide critical intelligence to prevent disruptions.
Concerns over the vulnerability of these cables have led NATO to launch
"Baltic Sentry," a mission using warships, drones, and aircraft to monitor
activity in the region, but since constant surveillance is not always
possible, demand for fibre optic acoustic sensing solutions is growing.
"It`s good that Nato and the European Union have woken upThe question is how
quickly you could establish contact with a vessel," said Thorsten Benner,
co-founder and director of the Global Public Policy Institute.
Maintaining secure communications in this environment requires the same level
of reliability as the best network switches , ensuring smooth data flow and
minimal disruption.
Companies such as Optics11 and Viavi Solutions are seeing increased interest
in their monitoring technology, which can be deployed on military submarines
or along key underwater infrastructure routes.
AP Sensings system is already in use in parts of the North Sea, but the
technology has limitations, requiring signal interrogation points at regular
intervals along the cable and having a sensing range of only a few hundred
metres, meaning it can detect nearby threats but is not a complete security
solution on its own.
