FIBER OPTIC CABLE CONSTRUCTION

Before any detailed discussion on how to handle optical fiber cable, some brief discussion of fiber and cable design is required. Eliminating confusion between the different terms, and providing an understanding of the cable construction will make handling the products less complicated. Fiber The cable cross-section in figure 1 demonstrates a two fiber cable for interconnect applications. […]
