There are three types of fiber optic cable commonly used: single mode, multimode and plastic optical fiber (POF). Transparent glass or plastic fibers which allow light to be guided from one end to the other with minimal loss. Fiber optic cable functions as a light guide, guiding the light introduced at one end of the cable through to the other end. The light source can either be a light-emitting diode (LED)) or a laser.
>> Fiber termination in the patch panel. Fiber optic cable can be terminated in a patch panel using both pigtail or field-installable connector fiber termination techniques. The pigtail approach requires that a splice be made and a splice tray be used in the patch panel. The pigtail approach provides the best quality connection and is usually the quickest.
