In any signal transmission system, the low loss splicing of transmission line segments is fundamental to optical performance and reliability. The precise nature of fiber optics demands a high level of skill and attention to detail on the part of the fiber technician. Unlike copper wire that relies on simple contact for a low attenuation splice, optical fibers must be correctly aligned and held in position to transfer a maximum amount of light across the splice. In addition, because the glass fiber is vulnerable at the splice point, it must be protected from the elements and from mechanical stresses. How to Cleave and Splice Optical Fibers will demonstrate the correct methods of preparing, cleaving, splicing, and protecting optical fibers. Learning the proper techniques is essential for any successful fiber technician.
