Verizon and NEC just made fiber sensing a whole lot easier
07 Octobre 2019 - 4:00PM
In a recent proof-of-concept field trial, Verizon and NEC were able
to use network infrastructure with existing fiber optic cables
already laid in the ground as distributed optical sensors to
collect information on city traffic patterns, road conditions, road
capacity, and vehicle classification information.
The trial used new optical sensor technology developed by NEC
with software underpinned by artificial intelligence (AI) for
intelligent traffic monitoring including the measurement of vehicle
density, direction, speed, acceleration, deceleration, and more.
Historically, companies have had to lay purpose-built fiber very
shallow in the ground with fiber grating at pre-determined
intervals to gather and synthesize this type of information. Now,
with optical sensor technology developed by NEC, Verizon is able to
use non-purpose built fiber already in the ground to generate
similar data. This new technology could lead to or improve
other solutions that support public functions such as helping first
responders detect and respond to gun shots and enhancing
municipalities’ ability to more quickly and efficiently identify
earlier deterioration of bridges, tunnels and other
infrastructure.
“This test marks an important milestone for technology that
could provide a huge leap forward for those building smart cities
and those tasked to manage them,” said Adam Koeppe, Senior Vice
President of Technology Planning and Development with Verizon.
“Instead of ripping up tarmac to place road and traffic-sensing
technology, cities will be able to simply piggyback Verizon’s
existing fiber optic network.”
Verizon is uniquely positioned to be able to scale this solution
nationwide. With hundreds of thousands of miles of fiber
already in place and plans to deploy 1,400 miles of additional
fiber per month, the breadth of geography where Verizon can mine
for data to assist municipalities’ efforts is substantial.
Technical details about the trial
This was all accomplished through a fiber sensing system that
coexisted with existing Wavelength Division Multiplexing (WDM)
communication channels on the same fiber with minimal impact to
data communication capacity, making it suitable for deployment even
in traffic congested networks. This marks the first time that a
36.8 Tb/s data transmission system and distributed optical fiber
sensing have been successfully demonstrated together through an
operational telecom network. Results from this trial were reported
jointly at OFC 2019 by Verizon and NEC (download PDF at

This is the first time and longest distance that such sensing
data has been collected through an operational telecom network. AI
tools such as Convolutional Neural Networks (CNN) and Software
Vector Machines were used in order to take advantage of Distributed
Intelligent Traffic Informatics (DITI). Utilizing just a single
integrated interrogator, the distributed multi-parameter sensor
system evaluated various properties of back-scattering light, which
can be used to derive the static strain, dynamic strain, acoustics,
vibrations and temperatures for each fiber segment. This allows
users to identify detected signatures and to translate those
back-scattering signals into actionable information over a wide
range of area previously unattainable by conventional sensors. With
this unique technology provided by NEC, Verizon is able to use
existing telecom networks, which were not built for sensing
purposes, to generate valuable new data and to automatically
analyze various environments.
“NEC has a strong history of leadership in the
area of optical fiber technology. The results obtained from this
joint research program with Verizon are a great advancement for
smart city business opportunities, especially for safer city
solutions such as the conservation of roads and the utilization of
traffic information. We are confident that these cutting-edge
solutions will provide meaningful new value for optical fiber
networks,” said Atsuo Kawamura, Executive Vice President of
NEC.
