Title: Fiber Optic Cable

The Complete Guide on Fiber Optic Cables
What is a Fiber Optic Cable?
  • Fiber optic cables are made of thinnest strands
    of glass that enable the transmission of
    information as light. A fiber optic cable may
    contain a huge number of glass strands from a few
    to millions. These cables carry information by
    using a light-based technology.
  • The main part of the cable is known as core where
    light particles travel through. There is another
    layer wrapped around the core, called cladding
    that keeps light particles inside the core. When
    light signals are sent through the fiber optic
    cable, they reflect off the core. These light
    signals dont travel at the speed of light. They
    travel around 30 slower than the speed of light,
    and this is because of the denser glass layers

Types of Fiber Optic Cables
  • Single-mode Fiber
  • There are mainly two types of fiber optic cables
    - single-mode fiber cables and multimode fiber
    cables. Single-mode fiber cables are the simplest
    cables. These cables have thin core around 5-10
    microns. These fiber cables are generally used
    for TV, internet, and telephone signals. Due to
    very thin, signals travel down the cable without
    bouncing off the edges.

Types of Fiber Optic Cables
  • Multimode Fiber Cables
  • Multimode cables are ten times bigger than
    single-mode cables. These cables are used to send
    information over short distances because light
    signals bounce off the edges. Since these cables
    have broad diameter, it results in more data
    transmission. However, this also means that there
    is a huge risk of signal loss and interference.
  • Fiber optical cables are better than traditional
    copper cables because of higher bandwidth and
    faster speed.

Uses for Fiber Optic Cables
  • Computers - Due to higher bandwidth and less risk
    of signal interference, fiber optics are used in
    computer networking.
  • Broadcasting - Fiber optic cables are used in
    broadcasting to carry data for lots of channels.
    Higher bandwidth provides better connections and
  • Medical Instruments - These are fiber optics that
    have enabled medical practitioners to peer inside
    our bodies without cutting off.
  • Military and Space - Fiber optic cables are used
    to connect military equipment such as missile
    launch sites and radar tracking stations. Since
    these cables don't give off electromagnetic
    radiation, enemies cant detect presence.
