The world of telecommunications, dominated by copper cable networks for years, is slowly incorporating fiber optics. Fiber optics, or optical fiber fax list as they are also known, transmit information as light pulses through a glass or plastic strand. They are useful in high-performance and long-distance data networking.An optical fiber contains glass or plastic strands ranging from fax list a handful to a couple hundred. A glass layer known as cladding surrounds these fibers. The buffer layer, another layer of glass, supports the cladding and the jacket layer is the final layer of protection for the individual strands.Transmission of data across the fiber occurs through light particles or photons fax list that pulse through the fiber.
The cladding and glass fiber core refract the fax list incoming light at different angles based on their refractive index. Once the photons are sent through the glass fibers, they reflect off the cladding and the core in zigzag bounces in a process called total internal reflection. These pulses travel at a speed 30% lesser than light because they travel through a denser fax list medium: glass.There are two major types of fiber optics: single mode and multi mode. Single mode fiber optics are used for long-distance communication due to the glass core's reduced diameter, which also cuts the loss of signal strength-or attenuation. Single mode fiber support higher bandwidth over longer distances, and the light source is mainly a laser. They are expensive because fax list high-level precision is required to channel the light through glass strands with small diameters.
Multi mode fibers are best suited for short-distance fax list communication. The larger diameter of the glass core allows multiple light pulses to be sent across the glass strand simultaneously and transmit more data. However, it means that there is a higher possibility of signal reduction, interference or loss. LED is the typical source of light for Multi mode fibers.Fiber fax list cables can support higher bandwidths than copper wires, and light can move further without a boost. They are less susceptible to interference, can be submerged in water and are stronger, lighter and thinner than copper cables. Most importantly, they do not have to be replaced or fax list maintained frequently.
