Influence of optical connectors and of other effects on optical link attenuation

In this time the metalic wires meet not the requirements of high capacitance and rate wire and so the new, modern fiber wires are more and more being used. This bachelor`s thesis deals with three basic kinds of connections of fiber wires, optical connector, mechanical coupling a optical weld, and their effect on optical link attenuation realized by fiber optics. The optical link is possible realized number of kinds fiber optics. In this thesis are most often used multimod and a little multimod fiber optics. By mechanical coupling are explored their effects of attenuation on optical link a their detrition after disconnection and next connection back to the optical line. For optical weld is explored quality assignet optic welder. For optical connectors is explored their quality of cleanness through apparatus OTDR( Optical Time Domain Reflectometer) and geometrical properties through apparatus FIBO 250
