The International Day of Photonics is held every two years to recognize and promote the role of photonics in our world. On this day (October 21 in 2016), organizations work to raise awareness about photonics and the important role that it plays in our lives.
In fact, photonics is a key enabling technology for a wide range of products that surround us. LED lighting, photovoltaic solar energy, photonics integrated circuits, optical components, lasers, sensors, imaging, displays, projectors and optical fiber are only a few of today’s technologies that incorporate photonics.
At OFS, we design, manufacture and provide optical fiber, fiber optic cable, connectivity and fiber-to-the-subscriber (FTTx) products. Our solutions cover a broad range of applications including telecommunications, medicine, industrial automation, sensing, government, aerospace and defense.

Different applications and optical fiber types present varying requirements for fiber coatings. When specialty optical fibers are used in demanding conditions, the fibers require coatings that are sustainable when subjected to harsh circumstances.
In fact, the successful deployment of fiber in these environments can often depend far more on the fiber’s protective external coating rather than its internal optical design. Fibers may be under attack from high and low temperature ranges, excessive humidity, high pressure, aggressive chemicals, mechanical interactions or any combination of these elements.
A recent OFS white paper in NASA Tech Briefs evaluates the stability of commercially available and in-house formulated, acrylate-based coatings to help determine the optimum coating for a range of conditions. To read more, please go HERE.
To support the exponential growth of global data traffic, 100 Gb/s submarine transmission systems are being installed in transoceanic links. These systems offer capacity up to ~10 Tb/s on a single core fiber using a C-band Erbium doped fiber amplifier (EDFA).
However, there are distinct challenges involved in developing and deploying high-capacity transoceanic distance transmissions systems. One issue is the need to improve optical signal-to-noise ratio (OSNR) within the entire C- and L-bands. Another limitation lies in delivering electrical power to the offshore equipment supplying EDFA pumps. In addition, long haul undersea submarine systems are typically much longer than terrestrial systems and have unique requirements for fiber optic cables and repeaters used in harsh subsea environments.
In a new white paper presented at SubOptic 2016, OFS and OFS Labs researchers discuss key fiber and amplifier technologies that help users to achieve high capacity and long reach for submarine transmission systems. These technologies include ultra-large-effective area, low loss optical fibers and their impact on performance, along with key amplification techniques for both repeatered and repeaterless submarine systems.
