  1. Could “Twisted” Fiber Optics Create a 100 Times Faster Internet?

    Leave a Comment

    Researchers at Australia’s RMIT University recently discovered a new fiber optic breakthrough that could lead to 100 times faster internet speeds. This new development detects light that has been twisted into a spiral.

     

    According to research in Nature Communications, developers could upgrade existing fiber optic networks and boost efficiency using this discovery.

     

    HOW IT WORKS

    Fiber optic cables use pulses of light to transmit information. However, users can only store that data based on the color of the light and whether the light wave is horizontal or vertical.

     

    The RMIT researchers twisted light into a spiral and created a third dimension for light to carry information – the level of orbital angular momentum, or spin. Dr. Min Gu of RMIT compared it to the double helix spiral of DNA. According to Dr. Gu,  a greater amount of angular momentum allows an optical fiber to carry a larger amount of information.

     

    Researchers have used “twisted light” approaches and orbital angular momentum before. They encoded a greater amount of data in various degrees of twist using these “twisted” methods. In fact, researchers at Boston University and the University of Southern California developed an optical fiber that could twist light. However, the teams used detectors as large as “the size of a dining table.” The RMIT researchers created a reasonably-sized detector that reads the information it holds. The new detector is the width of a human hair.

     

    WHAT IT CAN DO

    Providers could upgrade networks around the globe with this new fiber optic technology. These companies include the NBN Co. NBN is deploying Australia’s national broadband network. The company expects to complete this network by 2020.

     

    NBN is “prepared for future demand.” However, they have also stated that fiber optic advances such as this one by RMIT need further testing and acceptance before being deployed. A spokesperson commented, “Laboratories continually test new communications technologies for many years before they are commercialized. Equipment manufacturers and network operators must accept these new methods on a widespread scale before they are ready to be deployed in the field.”

  2. Make Way for High-Density Fiber Optic Cables

    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 be a game changer for today’s network operators. And it’s why “High Density” is also a critical word for many service providers today.

     

    With microcables and rollable ribbon cables that increase fiber density while saving on space, OFS is your high-density fiber optic cable solutions provider.

     

    Rolling In the Optical Fiber

    Rollable Ribbon fiber optic cables are one of the most exciting outside plant (OSP) cabling technologies today. These cables feature rollable ribbons, the newest fiber ribbon design from OFS. This ribbon can be “rolled” (compacted) and routed like individual fibers, allowing the use of smaller closures and splice trays.

     

    With up to 3,456 fibers, OFS AccuTube®+ Rollable Ribbon (RR) Cables help network operators double their fiber density in the same size duct or space. They also enable very efficient, cost-effective mass fusion splicing and easy individual fiber breakout. This ability helps simplify installation and save on labor costs. And by maximizing duct use, high-density AccuTube+ RR Cables are an excellent choice for connecting very large fiber distribution hubs. They are also very suitable for data centers, FTTx and access networks.

     

    Taking Things Indoors……

    With the award-winning AccuRiser RR and AccuFlex® RR Cables, network operators can bring the benefits of rollable ribbon cables indoors. The innovative indoor/outdoor AccuRiser RR Cable helps ease cable installation over ladder racking and through tight bends during routing. This high-density cable is excellent for use in data centers or central offices. It’s also a great choice for building-to-building cable connections along with routing for terminations and frames, and preconnectorized applications.

     

    The strong yet flexible, plenum-rated AccuFlex RR Cable helps prevent installation problems such as packing density, routing and deployment speed. This cable’s flame rating meets NFPA 262, allowing the cable to be installed into air-handling spaces. The AccuFlex RR Cable is an outstanding solution for data centers, central offices and head ends.

     

    With Limited Space, Go Small (and Dense)

    To help solve the problem of deploying or upgrading crowded FTTx or underground networks, OFS created the high-density MiDia®Microcable family. Optimized for exceptional air-blown installation, MiDia microcables can help lower installation costs while increasing fiber optic density and capacity in limited spaces. The MiDia Cable portfolio includes MiDia Micro FX CableMiDia Micro GX Cable and MiDia200 Micro FX Cable.

     

    And for network operators who prefer ribbon cables and the benefits of mass fusion splicing, OFS offers the AccuRibbon® DuctSaver® FX Cable. This cable makes optimal use of valuable duct space. It also maximizes the key advantages of air-blown microduct installation: rapid deployment and service turn-up.

  3. 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 Kingdom, Italy and Malta have found a way to use submarine fiber optic cables already deployed on the ocean floor as seismic detectors. In a paper published in the journal Science, the research group outlines how they discovered this capability and how it would operate.

     

    Giuseppe Marra, a member of the group, was testing an underground fiber cable between two locations in the United Kingdom. Noticing a small slowdown in signal delivery, he traced it to tiny vibrations bending the light. He then determined that the vibrations were caused by a remote earthquake. This discovery inspired him to explore using fiber optic cables as seismic detectors.
