This article explores the key testing standards and methods used to control insertion loss in fiber optic patch cords, helping businesses ensure product quality and system efficiency. Insertion loss (IL) and return loss (RL) are key performance indicators of fiber optic patch cords. While this was only a minor issue, it greatly affected both the optical alignment and, as indicated by test results in the field, return loss, which ideally should be approximately -65 dB, increased to 20 dB or more because of light reflecting into transceiver modules.
