摘要

TLDRThe video illustrates the intricate process of creating fiber optic cables, which carry voice and data through light pulses. It starts with large glass tubes that are cleaned and fused to form longer tubes. A chemical reaction inside these tubes creates a core made of soot, which is then converted to glass. The process includes heating and drawing this preform into thin fibers that are monitored for diameter precision. Finally, a protective acrylic coating is applied, and the fibers are either shipped or assembled into cables. Compared to copper cables, fiber optics provide superior data transmission capabilities and are less prone to interference.

  • 00:00:34
    then they submerge them in a corrosive

    bath of hydr Floric acid that removes
  • 00:00:40
    any oil
  • 00:00:42

    temperature at about

  • 00:01:35
    devices as the gas is heat they undergo
  • 00:01:38
    a chemical reaction that leaves a white
  • 00:01:40
    soot on the inside of the glass
  • 00:01:42
    tube the heat fuses the soot forming
  • 00:01:45
    what will eventually become the core of
  • 00:01:47
    the optical fiber the glass tube itself
  • 00:01:50
    will form the fiber's covering when
  • 00:01:53
    there's enough fuse soot they turn up
  • 00:01:54
    the heat until the soot itself turns
  • 00:01:56
    into glass then they heat the glass tube
  • 00:01:59
    enough to soften it and to soften the
  • 00:02:01
    new glass inside the intense heat
  • 00:02:04
    eventually makes the tube collapse on
  • 00:02:05
    itself to form a solid Rod the internal
  • 00:02:09
    structure of the optical fiber has been
  • 00:02:12
    achieved but it's in the form of a big
  • 00:02:14
    bulky Rod called a preform so the next
  • 00:02:17
    step is to thin it out first they excise
  • 00:02:20
    the preform from the uncollapsed section
  • 00:02:22
    of the glass
  • 00:02:25

  • 00:03:28
    spoon
  • 00:03:30
    then using a glob of glass as a weight
  • 00:03:33
    they stretch the soft glass and keep
  • 00:03:35
    stretching it until they formed a thin

    fiber a series of pulleys measure the
  • 00:03:44
    tension on the fiber as it's being drawn
  • 00:03:47
    a special monitor makes sure the fiber
  • 00:03:49
    is precisely the right diameter just 5
  • 00:03:52
    1000 of an
  • 00:03:56
    inch then the fiber passes through UV
  • 00:03:59
    lamps that bake on an acrylic coating to
  • 00:04:01
    protect against dust and other
  • 00:04:04
    contaminants finally the fiber is rolled
  • 00:04:06
    onto a
  • 00:04:07
    drum from here it's either shipped out
  • 00:04:10
    as is or put into a
  • 00:04:12
    cable fiber optic cables are expensive
  • 00:04:15
    to produce but they're smaller and
  • 00:04:17
    lighter than traditional copper cables
  • 00:04:20
    they carry more information and need
  • 00:04:22
    fewer repeaters to keep the signal from
  • 00:04:25
    deteriorating and unlike copper cables
  • 00:04:27
    they're immune to electromagnetic
  • 00:04:30
    interference they're also hard to tap
  • 00:04:32
    without being detected and all this is
  • 00:04:35
    made possible by a complicated process
  • 00:04:37
    based on a very simple principle light
