Searching Deep Space via Optical Fiber

For the first time, researchers have shown that a stable frequency reference can be reliably transmitted for more than 300 kilometers over a standard fiber optic telecommunications network in order to synchronize two radio telescopes.

In The Optical Society of America’s Optica journal, researchers from a consortium of Australian institutions recently reported this successful transmission between two radio telescopes using an optical fiber link. They also demonstrated that the technique’s performance was superior to using an atomic clock at each telescope.

Stable frequency references, used to calibrate clocks and instruments that make ultra-precise measurements, are usually only available at facilities that use expensive atomic clocks to generate the references. This new technology could help scientists anywhere to access the frequency standard by simply tapping into the telecommunications network.

This new technique required no substantial changes to the rest of the fiber optic network and was easy to implement. Most impressively, the demonstration was performed over a fiber optic network that was transmitting live telecommunications traffic at the same time. By running the experiment on optical fibers carrying normal traffic, the researchers showed that transmitting the stable frequency standard did not affect the data or telephone calls on other channels.

Changing the Rules of Light

Physicists have discovered a totally new light form that could change our fundamental understanding of the nature of light and also lead to faster and more secure fiber optic communication.

Researchers often measure a light beam through its angular momentum (a constant quantity that measures how much that light is rotating or spinning). Until now, they believed that, for all forms of light, the angular momentum would be a whole number multiple of Planck’s constant (a physical constant that sets the scale of quantum effects).

However, Irish scientists at Trinity College Dublin and the CRANN Institute demonstrated that a new light form exists where the angular momentum is only half of its typical value. While this difference seems small, it is profound: this fundamental property of light, which physicists always believed was fixed, can be changed. The researchers expect this discovery to shake up scientists’ understanding of light and also have real impact on the study of light waves in areas such as fiber optic communications.

OFS Labs “Tech Talks” Hollow-Core Optical Fiber

It’s not easy to confine light to an air core fiber using traditional guidance  guidance methods e methods such as total internal reflection.

In a new Tech Talk presentation, Brian Mangan of OFS Labs discusses the characteristics of hollow-core single-mode fibers. He also demonstrates the attenuation dependence of these fibers and how, using fibers that guide light in air, users can extend the wavelength range of silica fibers out to the infra-red.

Meeting the Data Center Demand for Increased Bandwidth

Today’s data centers are increasingly using 40 and 100 Gb/s Ethernet speeds. Work is also underway to develop 400 Gb/s Ethernet and 256 Gb/s Fiber Channel standards for next-generation networks. How are the optical fiber and structured cabling industries responding to this growth in demand for bandwidth?

To learn more, mark your calendar to hear OFS’ John Kamino (BICSI RCDD) cover this and other topics during his “Next-Generation Multimode Fiber” presentation at the BICSI Winter Conference in Orlando on Tuesday, February 2, 9:30 a.m.-10:30 a.m.  For more information on this topic, please go HERE.

Advanced Fiber Optic Technologies for Next-Generation Networking

If you missed the recent webcast on “Advanced Fiber Optic Technologies for Next-Generation Networking,” you’re in luck.  This webinar produced by Cabling Installation & Maintenance, is still available for viewing.

The seminar examines several of the latest developments in fiber optic cabling infrastructure and also places specific emphasis on how these advancements position optical fiber as a medium prepared for the next generation of networking.  To access the webcast, please go HERE.

Meeting the Need for Speed

Bandwidth demand continues to grow unabated and is predicted to increase at a compound annual rate of nearly 25 percent over the next five years.  The use of virtualization in servers has driven intra-data center traffic to new levels, while the rapid deployment of cloud computing applications is creating demand for higher-speed enterprise networks.

In a new article in BICSI’s ICT Today, John Kamino and Roman Shubochkin of OFS discuss how the optical fiber and cabling industry is supporting this need for higher network speeds by developing a new, next-generation multimode fiber – wideband multimode fiber.  Learn more here!

 

Managing Change in Data Center Cabling and Systems

From network cabling to supporting infrastructure, every system in a data center must deliver solid, consistent performance.  However, because data centers are subject to frequent reconfiguration, they must also be adaptable to change.

A recent webcase seminar from Cabling Installation & Maintenance provides an inside look at technologies that can help data centers to meet the challenge of remaining both dependable and flexible.

 

OFS Showcases Fiber Optic Technical and Industry Leadership

On Monday, June 29, OFS will highlight its continuing technical and industry leadership in a series of events at the 2015 FTTH Connect conference in Anaheim, California.

John George, Director of Solutions and Professional Services, will moderate a panel and breakout session focused on Multiple Dwelling Unit (MDU) strategies and solutions. In a separate session, Mark Boxer and Jeff Bush will provide a comprehensive look at Fiber-To-The-Home (FTTH) basics, including a comparison of FTTH to other available technologies.
