I am assuming this is not about testing the cable itself, but how it is being used in a system. It is not the sort of question you would ask unless you have come to suspect that it has not been installed correctly because it has been observed that the device the cable connects is not working. The problem need not be the cable.

A fiber drop is a process of connecting a fiber service provider’s access point, through fiber optic cable, to the optical network terminal (ONT) on the side of a customer’s home. New service activation requires the installation and connection of a fiber “drop” cable, from the “household passed” point, to the home. This location is referred to as a “drop” point and can take the form of a fiber pedestal (above-ground access point), handhole, manhole, chamber, or utility/telephone pole.
