The most well-known of these courses are those offered by the Fiber Optic Association (FOA). FOA courses put an emphasis on fiber optics for technicians and include splicing, connectors, testing, OSP installation and fiber characterization. Let us begin with understanding what exactly these fiber optic cables are; it is firstly a cluster of network cables that contains certain glass fibers in the form of strands that are placed inside an insulated casing.
They are specifically designed for long distances, a performance data networking that is very high as well as telecommunications. If you compare the function and potential of these with the wired cables, these optic cables have a much higher bandwidth and thus have the capability of transferring data over long distances. Of course there are a certain reasons behind companies making use of this material of fibers rather than any else.
