What is Distributed Acoustic Sensing (DAS)?

Leave a Comment

Distributed Acoustic Sensing (DAS) is a technology that enables continuous, real-time measurements along the entire length of a fiber optic cable.  Unlike traditional sensors that rely on discrete sensors measuring at pre-determined points, distributed sensing utilizes the optical fibre. The optical fiber is the sensing element. AcoustiSens® Wideband Single-Mode Optical Fiber, the newest addition to […]


A Hollow-Core Fiber Cable for Low Latency Transmission – when microseconds count

Leave a Comment

AccuCore HCF™ Optical Fiber Cable is the world’s first terrestrial hollow-core fiber (HCF) cable solution. Light travels about 50% faster in a hollow core optical fiber compared to the solid silica core of conventional fiber. Consequently, light transmitted in a hollow-core fiber arrives 1.54 microseconds faster for each kilometer traveled compared with conventional optical fiber. […]


The OFS Fiber Connection in The U.S. Virgin Islands

Leave a Comment

The co-inventor of optical fiber, Dr. Peter Schultz, is a resident of the Virgin Islands. He was instrumental in convincing the local authorities back in the early 2000’s that the islands needed high-speed connectivity afforded by optical fiber. He assisted in the successful lobbying of federal and local governments to provide funding for the project […]


New Fiber Optic Gyroscope: More Precise, Smaller than a Grain of Rice

Leave a Comment

Engineers at the California Institute of Technology have created the world’s smallest fiber optic gyroscope. Five hundred times smaller than a regular gyroscope, this new gyro can fit on a grain of rice. This research breakthrough could lead to more accurate fiber optic gyros compared to mechanical units. WHAT OPTICAL GYROS DO Advanced fiber optic […]

Melting Arctic Ice Could Mean Faster Internet for Some

Leave a Comment

Have you ever wondered how an e-mail reaches your inbox from a co-worker in Europe? Or how a Facebook message gets to you from a cousin in Africa? The answer lies beneath the ocean. More than 745,000 miles of submarine cables featuring optical fiber make up most of the actual physical internet. These cables wind […]

Make Way for High-Density Fiber Optic Cables

Leave a Comment

More fiber density in less space. From 5G to data centers to FTTx, the picture is clear. Everyone uses more bandwidth than ever before. And while bandwidth demand may seem endless, the space to install fiber optic cable isn’t. That’s why being able to install more optical fiber in the same or less space can […]

Rural Broadband Projects to Receive $97 Million Investment from USDA

Leave a Comment

The United States Department of Agriculture (USDA) will invest $95 million to improve or expand access to broadband internet in the rural U.S. The 12 projects involved will include converting exchanges from copper to optical fiber and also building a fiber-to-the-home network to meet future demand. These projects will expand access to educational, social and […]

Optical Fiber “Senses” Surroundings

Leave a Comment

Companies use optical fiber as a sensor to detect changes in temperature and pressure. This technique is often used to monitor structures including bridges and gas pipelines. Now researchers at Ecole Polytechnique Fédérale De Lausanne (EPFL) have discovered a new method where optical fibers can identify when they are in contact with a liquid or […]

Invisibility Cloaking Could Help to Secure Data Sent Over Optical Fiber

Leave a Comment

Shades of Harry Potter’s invisibility cloak! A recent study in Optica describes a new way to achieve cloaking invisibility. In this method, researchers manipulated the frequency (color) of light waves passing through an object. This approach overcomes critical shortcomings in existing cloaking technologies. The research team says that this technique could help to secure data […]

Fiber Optic Cables as Undersea Seismic Monitors?

Leave a Comment

Detecting ocean-floor seismic activity is crucial to our understanding of the interior structure and dynamic behavior of the Earth. However, with 70% of the planet’s surface covered by water and only a handful of permanent, ocean-bottom seismometer stations, very little overall seismic activity is actually recorded.   Now, a group of researchers from the United […]
