• Prysmian color code with black stripes
    Prysmian uses the US industry standard repeating 12-color sequence. When cables go beyond 12 units, the colors repeat but use a stripe to distinguish units. Individual tubes containing 24 fibers have a blue and orange colored binder thread separating the two 12 fiber groups.

    Have you ever wondered how are the world’s continents connected between them? They are definetly not using radio equipment but cables layed on the bottom of the ocean. You cand find a regulary updated map by HMN Technlologies right here:
  • Optical fibre cables, how do they work?
    Have you ever thought about how you get emails or any other information, from any corner of the world, within a blink of an eye? This has been made possible by a network of cables, which are laid under the ground and below the ocean. The cables, which carry most of the world’s data, are […]
  • Fibre Optic Terms and Definitions
    A Absorption The portion of optical attenuation in optical fiber resulting from the conversion of optical power to heat. Caused by impurities in the fiber such as hydroxyl ions. Due to impurities inherent to the fiber’s manufacture and internal molecular structure, a small percentage of the signal strength is absorbed and released as heat within […]
  • Fibre Optic History
    The first attempts at guiding light on the basis of total internal reflection in a medium dates to 1841 by Daniel Colladon.                   In 1880, Alexander Graham Bell demonstrated how light could be used to transfer sounds from one area to another. Though it did not work […]
  • Network Architectures
    New network architectures have been developed to reduce the cost of installing high bandwidth services to the home always using the acronym FTTx (Fiber to the x).The most used terms are: FTTH (Fiber-to-the-Home): Optical fiber connection, reaches the boundary of the living space, such as a panel box on the outside wall of a home.
