Abstract

This test is performed on optical fiber cables that have connectors at each end. In a first step of the test, a first cable is connected between a light source and a light receiver, and the light at the receiver is recorded. The amount of light measured at the receiver is reduced by the losses at the connection to the light source and the losses in the first fiber cable. It is also reduced by the losses at the light receiver, but these losses are negligible because the light receiver is larger than the cone of light from the end of the fiber. The first measurement is used as a reference, and the losses in the connection to the light source and losses in the fiber are thereby canceled in the final test results.
