What is Fiber Optic Media?

Answer 1

An optical cable is a plastic or fiberglass wire that transmits digital audio from one device to the other.

Answer 2

You may know that fiber optic cabling is important to applications like the internet, telephone systems and cable TV, but have you ever wondered about how it actually works, or why it's so perfect for transmitting data? We at Cablesdotcom thought you might be curious, so read on to find out what exactly goes into making fiber optic cable, and just how much it's capable of.

Fiber optic cabling is based on optical fibers, which are long, flexible, hair-width strands of ultra-pure glass. Optical fibers are formed when preform blanks - portions of specially manufactured glass - are heated to between 3000 and 4000 degrees and then drawn out at a rate of up to 66 feet per second. As optical fiber is pulled, it is constantly monitored by a laser micrometer, which ensures that its diameter is perfectly uniform from start to finish.

In order for optical fibers to transmit data over long distances, they need to be highly reflective. On their way to being spooled, newly-pulled glass fibers pass through coating cups and ultraviolet ovens, which respectively apply and then cure the thin plastic buffer coating that creates a mirror effect within the fiber.

The finished optical fiber is then extensively tested in a wide range of categories, including Tensile Strength, Refractive Index Profile, Fiber Geometry, Attenuation, Bandwidth, Chromatic Dispersion, Operating Temperature, Temperature Dependence of Attenuation, and Ability to Conduct Light Underwater. After testing has proven that the newly-manufactured optical fiber meets all standards, it is sold for use in fiber optic cabling.

Depending on what type of application it will be used for and how much data it will need to transmit, fiber optic cable can be built around a single strand of optical fiber, or larger groupings of it. To assemble a complete fiber optic cable, the strand or cluster of optical fiber is placed at the core, to be surrounded by a loose tube of PVC, which leaves the fiber room to bend when being routed around corners and through conduit.

In order for the finished cable to transmit data signals, it needs to be connected to the two other main components of a fiber-optic system. The first of these is the optical transmitter, a device which converts electrical and analog signals into either On-Off or Linear modulating light signals, then releases that data into the fiber optic cable. The cable then relays the data emitted by the optical transmitter to the optical receiver, which accepts the light signal and reformat the data into its original form.

Fiber optic cabling has advantages over standard copper coaxial cables, in that it can transmit larger quantities of data with far less loss, is able to maintain signals over long distances, carries little risk of corrosion, and is virtually free from interference.

In the telcos, singlemode fiber is used to connect long distance switches, central offices and SLCs (subscriber loop carriers, small switches in pedestals in subdivisions or office parks or in the basement of a larger building). Practically every telco's network is now fiber optics except the connection to the home. Fiber to the home is not yet cost effective - especially since most homes do not want (nor are willing to pay) for the high speed services that would justify fiber optics.

Answer 4

An optical fiber (or fibre) is a glass or plastic fiber that carries light along its length. Fiber optics is the overlap of applied science and engineering concerned with the design and application of optical fibers. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher data rates (a.k.a "bandwidth") than other forms of communications. Fibers are used instead of metal wires because signals travel along them with less loss, and they are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so they can be used to carry images, thus allowing viewing in tight spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers.

Answer 5

Basically, Fibre Optic cables use light to transmit data across a distance, rather than an electric current. The main advantage of this system is that light can travel much faster than electric signals can.

Fibre Optic cables are mainly chosen for long distance data transferring applications that need to get a lot of data across quickly.
