What is Fibre Optic?
Fiber optic (or "optical fiber") refers to the medium and the technology associated with the transmission of information as light impulses along a glass or plastic wire or fiber. Fiber optic wire carries much more information than conventional copper wire and is far less subject to electromagnetic interference. Most telephone company long-distance lines are now fiber optic.
Transmission on fiber optic wire requires repeating at distance intervals. The glass fiber requires more protection within an outer cable than copper. For these reasons and because the installation of any new wiring is labor-intensive, few communities yet have fiber optic wires or cables from the phone company's branch office to local customers (known as local loop).

Fiber optics has several advantages over traditional metal communications lines:
fiber optics

  • Fiber optic cables have a much greater bandwidth than metal cables. This means that they can carry more data.
  • Fiber optic cables are less susceptible than metal cables to interference.
  • Fiber optic cables are much thinner and lighter than metal wires.
  • Data can be transmitted digitally (the natural form for computer data) rather than analogically.


Fiber Optical Manufacturing Process


Raw Materials: 


  • The raw materials used in the initial stages
  • of optical fibre manufacture include high
  • quality synthetic quartz substrate tubes,
  • ultra-pure halides such as silicon
  • tetrachloride (SiCl ) and germanium
  • tetrachloride (GeCl ), as well as the gaseous
  • forms of pure oxygen (O ), Helium (He),
  • Chlorine (Cl ), Sulphurhexafluoride (SF )
  • and Nitrogen.
  • It is important that the above materials are
  • free from foreign articles, and contain very
  • low concentrations (<5 ppm) of water
  • molecules.


  • Deposition:
     An oxy-hydrogen burner heats a section of the rotating quartzsubstrate tube to 1700 °C. This creates a radial reaction zone wherethe oxidation of the halides occurs. The silicon dioxide (SiO ) andgermanuim dioxide (GeO ) particles are deposited in the inside ofthe tube, downstream from the burner, by a process known asthermophoresis. Chlorine which acts as a drying agent, is producedas a waste product. As the burner repeatedly passes over the tube,it sinters and melts the layers of sooty particles into successive layersof glass. In the final few layers, the concentration of germanuimdioxide (GeO ) is increased, thereby creating a region of higherrefractive index that will become the fibre core.


    Collapse:
    Once the required number of layers of glass with the appropriate refractive index have been deposited and sintered by the burner, the tube is collapsed to form a solid glass rod called a preform.

    Sleeving:
    In order to increase the length of fibre that can be drawn cost effectively from a single preform, the preform volume is increased by sleeving. This is done by inserting the preform into a thick syntetic quartz glass tube. The two are then fused together at 2000 °C using an oxy-hydrogen ring burner, which moves vertically upwards.

    Optical Fibre and Cable Testing
    Performance verification forms an integral part of the manufacturing
    of optical fibre. The capability of each length of optical fibre to meet
    the required optical, geometrical, mechanical and dispersion
    characteristics is determined for each length of fibre before it is cabled.
    The optical attenuation is rechecked after cabling, in order to verify
    that it has not been significantly altered by the cabling process.
    The capability of the cable to withstand the rigours of installation and use are determined using a wide range of mechanical tests that include bending, flexing, torsion, impact resistance and crush tests. This is done using specially designed equipment that simulates field conditions
    according to international standards. Special emphasis is placed on tensile strength and environmental performance. ATC uses a holistic approach to achieve an integrated cable/clamping system for aerial self-supporting cables. Special test facilities and test methods are used to ensure long-term system reliability


    How to Start a Fibre Optic Business?


    Startup entrepreneurs slave over the creation of their business plans, investing countless hours in the details of their startup strategy. Now it's time to address details about your industry.
    Industry analyses are standard chapters in fiber optic communications company business plans and are often required by lenders or investors. Industry analyses are critical for contextualizing your startup within an industry setting.
    To succeed, you'll need to be careful to avoid common industry analysis mistakes and to accurately represent your startup in an industry context.

    Evaluate Competitors
    Before you open a fiber optic communications business within your community, it's essential to determine how you will fit in the competitive landscape. Use the link below to find competitors nearby. Simply enter your city, state and zip code to get a list of fiber optic communications businesses in your town.
    It's important to be aware of what the competition is doing. Take the time to visit the competition to properly assess their strengths and weaknesses.

    A Good Source of Advice
    If you want to open a fiber optic communications business it's a wise move to learn from folks who are already in business. Local competitors are not going to give you the time of day, mind you. What's in it for them?
    On the other hand, an individual who has a fiber optic communications business in another town may be more than happy to give you a few tips, as long as they don't view you as a competitive threat. In fact, they are often very willing to share startup advice with you. It can take a while to find an entrepreneur who is willing to talk, but it's well worth the effort.
    How do you find a fiber optic communications business manager in another community?
    Here's one way to do it. Just use our link below, find somebody and call them.
    Gaining Access to Fiber Optic Communications Business Ownership
    As a fiber optic communications business entrepreneur, it's important to explore all of your options before you commit to a specific business opportunity. There are a lot of benefits of buying a fiber optic communications business.
    If you're on the fence consider this: There has never been a better time to acquire a fiber optic communications business. The down economy has resulted in a glut of available businesses, many of which can be acquired for bargain prices.

    Consider Buying a Franchise
    Your chances for thriving in your new business greatly improve when you franchise rather than going it alone.
    Prior to making the decision to open a fiber optic communications business, you would be wise to assess whether franchising might help you on your entrepreneurial journey.
    The link below gives you access to our franchise directory so you can see if there's a franchise opportunity for you. You might even find something that points you in a completely different direction.
    Business Overview

    Fibre optic cables and fibres are particularly important for the telecommunications industry (fibre broadband, for example) as well as used in medical, scientific, defence, and engineering industries.  Fibre optic cables are cheaper to make than traditional copper wiring, but installation costs for fibre optics are much higher.  According toPropeller, it costs around $1,000 to convert one household from standard to fibre optic broadband.  Despite these costs, the fibre optic industry is set to boom, thanks to the increasing demand for data to travel quickly across long distances.
