However, additional protection is often necessary when fibers are used in an environment where accessibility is open. While the bare glass fiber may have a typical diameter of micrometers, and the polymer buffer and jacket increase this to a few hundred micrometers, the total diameter of the fiber cable may be several millimeters.
This not only strengthens the cable, it also makes it easier for operators to recognize the fiber for ease of maintenance and repair. And a fiber cable can contain multiple fibers. This allows for the multiplication of already huge data transmission capability of a single fiber. There are many optical components can be directly made from fibers.
Some examples include. These are just a few example of how fiber optics are made and the things we can make out of them for use in many fields.
There are some technical areas like optical data transmission where optical fibers compete with electric cables , and there are other areas where fiber optic cables have significant advantages:. Alignment must be precise and optimal cleanliness is required.
The laser-powered signals carried on these cables are buried under the pavement and even under the ocean floor. The technologies that use these cables are as varied as light signals themselves. Fiber-optic cables primarily carry information over long distances. This creates optimal conditions for transmission of data. Fiber optic cables have many advantages over older styles of electronic transmission:.
Computers were once connected over long distances by telephone lines or Ethernet cables, but fiber cables have replaced those options because networking computers with fiber optics is affordable, reliable, secure, and offers higher capacity. While early television and radio signals used electromagnetic waves to transmit signals, cable TV companies transitioned forward using coaxial cables, and those carried a handful of analog television signals.
As cable consumer numbers grew and the television networks started to offer more channels and programs, cable operators switched from coaxial cables to optical fibers, from analog to digital broadcasting. Medical devices that help doctors look inside human bodies without cutting them open were the first application of fiber optics more than 50 years ago.
Now, gastroscopes and arthroscopes are commonplace in medicine, and fiber optics continue to become an important component in new medical scanning and diagnosis devices. Fiber-optic cables are cheap, lightweight, high-capacity, thin, robust against attack, and very secure.
As such, they are a seamless way to link military bases with missile launch sites and radar tracking stations. The relatively light weight of fiber cables compared to traditional wires is another benefit. Tanks, military airplanes, and helicopters have begun switching from metal cables to fiber-optic cables. Saving weight and costs is a great benefit, but fiber optics also improve reliability — their very nature makes them unsusceptible to an EM pulse or other jamming devices.
Fiber optics are revolutionizing the way people communicate, treat medical conditions, and upgrade military machines. Though fiber optics have been around for decades, our technology is just now catching up to using them to their fullest potential. In the near future, scientists and researchers will continue to find ways to incorporate fiber optics into our lives.
Also, fibre optic cables can transmit signals between different parts of the vehicle at lightning speed. This makes them invaluable in the use of safety applications such as traction control and airbags. Calling telephones within or outside the country has never been so easy. With the use of fibre optic communication, you can connect faster and have clear conversations without any lag on either side.
The use of fibre optics in the area of decorative illumination has also grown over the years. Fibre optic cables provide an easy, economical and attractive solution to lighting projects. As a result, they are widely used in lighting decorations and illuminated Christmas trees. Fibre optic cables are widely used in the inspection of hard-to-reach places. Some such applications are on-site inspections for engineers and also inspection of pipes for plumbers.
The use of fibre optic cables in the transmission of cable signals has grown explosively over the years. These cables are ideal for transmitting signals for high definition televisions because they have greater bandwidth and speed. Also, fibre optic cables are cheaper as compared to the same quantity of copper wire. With the high level of data security required in military and aerospace applications, fibre optic cables offer the ideal solution for data transmission in these areas.
Fibre optic cables have an array of uses that go beyond what most people are aware of. Hydrophone sensor systems are used by the oil industry as well as a few countries' navies. Both bottom mounted hydrophone arrays and towed streamer systems are in use.
The German company Sennheiser developed a microphone working with a laser and optical fibers. Optical fiber sensors for temperature and pressure have been developed for downhole measurement in oil wells. The fibre optic sensor is well suited for this environment as it is functioning at temperatures too high for semiconductor sensors Distributed Temperature Sensing.
Another use of the optical fibre as a sensor is the optical gyroscope which is in use in the Boeing and in some car models for navigation purposes and the use in Hydrogen microsensors.
