How Fibre Optic broadband works?

    Fibre-optic cables,using
    very thin glass or plastic
    material, enable the fastest
    ever connection speeds
    (equal to the speed of
    light) over your broadband
    line.
    The maximum speeds can
    vary depending on the
    fibre optic broadband
    technology used.
    Fibre to the Cabinet
    (FTTC) broadband which
    reaches the street cabinet
    via fibre cables and then
    users’ premises via copper
    wires can offer download
    speeds around 40Mbps.
    Fibre to the Home /
    Premise (FTTH or FTTP)
    broadband will use fibre
    for the entire installation
    of the line, right from the
    exchange up to the
    users’premises. This type of
    connections can offer
    speeds 100Mbps or above.

    Normal copper wire carried tha data in form of current conduction,but in fibre optics the light travels in the concept of total internal reflection.
    So,as a result if the inside of thw optical fibre is well mirror and protected,its likely to be less interfered from outside fields as like normal copper wire.

    Correctly stated, Light Travels through OFC cable due to total internal reflection.
    the advantage is Unlike RF, light signal is not sensitive to EM radiation.
    Another advantage is low attenuation (for which less repeaters needed, hence total network installation costs low)

    Least but foremost OFC cable doesn't have any price in retail market so less theft occurs.

    But the disadvantage of OFC is that you cant use it for extensive distribution like we do for normal cable.Like you can use it in a hum to provide server access to 5 computers since light cant evenly redistribute itself.

    Well bro you can use it, but the system will be very expensive.
    BTW light BW is virtually infinite(yes you just need is processing power), which we don't need while connecting our internet.

    exactly...its not necessary for simple data transfer user for home users...

    Yes that's the reason why we donot use OFC cable for our home uses.
    another problem with OFC si you need splicing to join OFC cable, whereas standard electrical cable can be joined even by hands.
