Optical fiber refers to the medium and technology associated with the transmission of information along with optical pulses of glass or plastic wires or fibers. Fiber is used for long-distance and high-performance data networks. Below the Fiber Optic Splice Closure manufacturer, fiber optics has become a part of people's lives.   The fiber transmits data in the form of light particles (or photons) that are pulsed through the fiber optic cable. The glass fiber core and the cladding each have a different refractive index, causing the incident light to bend at an angle. When optical signals are transmitted through fiber-optic cables, they are reflected from the core and cladding in a series of zigzag bounces, adhering to a process called total internal reflection. Due to the high density of the glass layer, the optical signal does not propagate at the speed of light but is about 30% slower than the speed of light. To update or enhance the signal throughout the journey, fiber optic transmission sometimes requires a remote repeater to reproduce the optical signal by converting the optical signal into an electrical signal, process the electrical signal and retransmit the optical signal.   While copper cable has been a traditional choice for telecommunications, networking and cable connections for many years, fiber optics has become a common alternative. The long-distance lines of most telephone companies are now made of fiber optic cables. Due to its higher bandwidth and faster speed, optical fibers carry more information than traditional copper wires. Since the glass is not electrically conductive, the fiber is not subject to electromagnetic interference and signal loss is minimized.
