Understanding how fiber optics are made and function for uses in everyday life is an intriguing work of art combined with science. Fiber optics has been fabricated from materials that transmit light and are made from a bundle of very thin glass or plastic fibers enclosed in a tube. One end is at a source of light and the other end is a camera lens, used to channel light and images around the bends and corners. Fiber optics have a highly transparent core of glass, or plastic encircled by a covering called "cladding". Light is stimulated through a source on one end of the fiber optic and as the light travels through the tube, the cladding is there to keep it all inside. A bundle of fiber optics may be bent or twisted without distorting the image, as the cladding is designed to reflect these lighting images from inside the surface. This fiber optic light source can carry light over mass distances, ranging from a few inches to over 100 miles.
There are two kinds of fiber optics. The single-mode fiber optic is used for high speed and long distance transmissions because they have extremely tiny cores and they accept light only along the axis of the fibers. Tiny lasers send light directly into the fiber optic where there are low-loss connectors used to join the fibers within the system without substantially degrading the light signal. Then there are multi-mode which have much larger cores and accept light from a variety of angles and can use more types of light sources. Multi-mode fiber optics also use less expensive connectors, but they cannot be used over long distances as with the single-mode fiber optics.
Fiber optics have a large variety of uses. Most common and widely used in communication systems, fiber optic communication systems have a variety of features that make it superior to the systems that use the traditional copper cables. The use of fiber optics with these systems use a larger information-carrying capacity where they are not hassled with electrical interference and require fewer amplifiers then the copper cable systems. Fiber optic communication systems are installed in large networks of fiber optic bundles all around the world and even under the oceans. Many fiber optic testers are available to provide you with the best fiber optic equipment.
In fiber optic communication systems, lasers are used to transmit messages in numeric code by flashing on and off at high speeds. This code can constitute a voice or an electronic file containing, text, numbers, or illustrations, all by using fiber optics. The light from many lasers are added together onto a single fiber optic enabling thousands of currents of data to pass through a single fiber optic cable at one time. This data will travel through the fiber optics and into interpreting devices to convert the messages back into the form of its original signals. Industries also use fiber optics to measure temperatures, pressure, acceleration and voltage, among an assortment of other uses.

Networking With Fiber Cables
Fiber cables form one of the most important parts of the networking industry today. Fiber cables are composed of one or more transparent optical fibers enclosed in a protective covering and strength members. Fiber cables are used to transmit data by the mode of light. Various types of fiber cables available are multimode duplex fiber cables, single mode simplex fiber cables, single mode duplex fiber cables, and plastic optical fiber cables.
There are many fiber optic cable manufacturers who manufacture full line of fiber cables in both single mode and multi-mode, simples, duplex and multi-strand. Several manufacturers provide low cost, quick-turn, high volume fiber cables and fiber cable assembly solutions.
Cables with complete assembly of fibers, strength members and jacket refer to fiber cables. These fiber cables come in variety of forms depending upon their usability and place of use. It is important to identify the exact requirement of fiber cables whether they would be easy to install, splice or terminate, etc. This is necessary as it ultimately decides the cost of installing the fiber cables.
Fiber cables are required to protect fibers from external hazards. Thus before installing the fiber cables one should always assess the place of installation of fiber cables. Fiber cables required inside the house or a building are not exposed too much of hazardous condition thus simpler form and not-so-tough fiber cables can be used for installation. But if the fiber cables are to be installed for longer distances and outside premises then the cables should be robust. They should also be installed well beneath the ground to protect them not only from ground digging, water logging but also from prairie dogs.
Fiber cables comes in different types based on their usage patterns as well. The zip cord and simplex fiber cables refer to those used for desktop connections. Simplex fiber cables are one fiber, tight-buffered and jacketed. A zip cord is actually two simplex fiber cables joined by a thin web. On the other hand fiber cables made of several simplex cables are breakout fiber cables. This type of fiber cables is strong, rugged and larger. They are also a bit expensive but prove to be economic where distances are not too long and fiber count required is less.
Small fiber cables required for dry conduit run, riser or plenum are known as a distribution fiber cables that needs a breakout –box to be broken up or terminated in a panel box. They contain several tight-buffered fibers bundled under same jacket.
Aerial fiber cables are good enough for outside installation where as armored fiber cables are used for under-ground wiring where rodents are a problem. These fiber cables have metal armoring between two jackets to prevent rodents from tampering the cabling connections.
Loose tube fiber cables are perfect for plant trunk applications to prevent fibers from moisture or water. They can be buried directly in ground but must be handled carefully to prevent damage. Ribbon fiber cables have twelve or more fiber cables packed together laid in a rows. They are also a plant fiber cables which are gel-filled and are good for water blocking.
All fiber cable manufacturers manufacture different fiber cables but their product literatures should be carefully studied so as to assess which type of fiber cables they specialize in.

Fiber Optics In The Real World
Optic fibers are used widely in the medical field for diagnosing and treating a variety of ailments. Because optic fibers can be made extremely thin and made into flexible strands, they can be used for insertion into blood vessels, lungs and other parts of the body. Optic fibers have been enabling physicians to look and work inside the body through tiny incisions with an instrument called an Endoscope. An Endoscope is a medical instrument made to carry two bundles of optic fibers inside one long tube. One bundle of optic fiber directs light at the tissue being examined, while the other bundle of optic fiber transmits light reflected from the tissue, producing a detailed image. Endoscopes may be designed to look into specific areas of the human body. For example, physicians can use the optic fibers in the Endoscope to examine knees, shoulders and other joints in the body.
Arthroscopy (pronounced ahr-THROS-kuh-pee) is a technique of using another medical instrument called the Arthroscope. This instrument is straight and cylinder-like with a series of lenses and optic fiber bundles that come in sizes of 1/12 to 1/5 inch (2 to 5 millimeters.) The Arthroscope is used to examine a joint in a body, such as knee joints, ankles, elbows, hips and shoulders. This is done by the Arthroscope being inserted into a joint of the body through a small incision. A light is then transmitted by the use of the optic fibers to the tip of the Arthroscope to illuminate the joint. The use of optic fiber through the Arthroscope enables a physician to thoroughly examine a joint for diagnosis or treatment.
Optic fibers used in the Arthroscope can be used to measure temperature and other bodily
attributes as well as being used in performing surgical procedures. The problem most commonly treated by Arthroscopy is torn cartilage in the knee. This is when a small incision is made at the joint for use of the optic fiber in the Arthroscope and then a second incision is made for the use of other surgical instruments to remove the cartilage. The primary advantage of using optic fibers through Arthroscopic surgery is that the operation can be performed through a small incision, resulting in the patient experiencing the least amount of discomfort and a healing time that is much shorter, when compared to the other methods of surgery.
Aside from the uses of the Endoscopes and the Arthroscopes, another widely used function of optic fibers in the medical field is the ability for the optical fibers to be inserted into blood vessels to give a quick and accurate analysis of blood chemistry. Physicians have also found medical use of the optical fibers to direct intense laser light at a wound to stop bleeding or to burn away abnormal tissue. Fiber optic training is necessary in the field of medicine. The use of optic fiber through medical science continues to grow rapidly to everyday to develop more new and advanced medical devices to enable physicians to provide people with better service.
