A visual inspection is required upon receipt of the cable coils and, in the event that visible damage is detected, that the cable in the coil be tested to determine its continuity before installation. That way, it is checked that you have not suffered any damage to the shipping path from the manufacturer to the workplace. Since the installation cost is usually high, often much higher than the cost of the materials, it is logical to ensure that the installed cable is in good condition and that it should not be discarded and replaced.
As usual, it is enough to verify continuity by means of a visual continuity plotter or a visual fault locator. However, cable reels can be tested with an OTDR if it is suspected that damage may exist and you want to document it or determine if part of the cable should be discarded (or retained for later reimbursement for damaged material).
After the installation and termination of the cable, each segment of the cable network must be evaluated individually, as installed, to ensure that each connector and each cable are in good condition. Finally, the loss of each end-to-end line must be assessed (from a device connected to the cable network to another), as required by all standards.
Each fiber in each cable must be evaluated. Therefore, the total number of tests to be performed is equivalent to the number of cable segments multiplied by the number of fibers in each cable. This process can take a long time.
