fiber optics
Fiber optics use light rather than electricity to transmit data. In a fiber optic system, electricity is converted into light by a LED (Light-Emitting Diode) or laser and sent down a run of fiber optic cabling. While in the cable, the light bounces off an inner metallic shield called cladding. This cladding keeps the light contained along the fiber optic strand. On the other end of the fiber optic run, a receiver converts the light signal back into electricity.Generally, fiber optic cables are made of three layers: the jacket, the cladding, and the core. The core is made of germania-doped silica which contains and reflects light. The surrounding cladding is made of pure silica and reflects the light that travels down the core. The jacket is made of an acrylate coating and protec
Telephone companies typically use this type of fiber because it can accommodate hundreds of phone conversations along one fiber. Multimode fiber gives you high bandwidth at high speeds over long distances. Multimode: Multimode's fiber optic core is much larger, usually 62. Immunity-Fiber optics are immune to interference. 4 ml), multiple paths of light can cause signal distortion at the receiving end, resulting in an unclear and incomplete data transmission. It only allows a single ray of light to pass through the fiber at a time. 5mm in diameter, than that of the singlemode fiber. This type of cable lends itself to very long runs. Fiber Optic Over View :Over the past few years, fiber optic cable has become more affordable. Security-Taps in fiber optic cable are easy to detect. However, in long cable runs (greater than 3000 feet [914. ts the cladding and core and allows for handling of the cable without touching the glass. The small core and single lightwave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and the highest transmission speeds of any fiber cable type.
