The typical process involves stripping the fiber coating, inserting and securing the fiber in a ferrule with adhesive, and then polishing the end using a series of films with progressively finer grits. Finally, the endface quality is checked, for example with a. A fiber optic pigtail is a short length of optical fiber cable with a factory-terminated connector on one end and a bare, exposed fiber on the other. The connector end is polished and tested under factory conditions, ensuring low insertion loss and high return loss. The bare fiber end. In most cases when a fiber is used, it is essential to prepare clean endfaces. We terminate fiber optic cable two ways - with connectors that can mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear or with splices which create a permanent joint between the two fibers.
