SRL is an abbreviation for structural return loss, a measure of the reflections caused by variations in a cable's impedance along its length.
SRL stands for structural return loss, a measure of how much signal is reflected back along a cable due to small, periodic variations in its impedance caused by the cable's construction. Even minor irregularities introduced during manufacturing, such as slight variations in dimensions, can cause reflections, and structural return loss quantifies these reflections over a range of frequencies. A higher structural return loss value, meaning less reflected signal, indicates a more uniform, higher-quality cable.
Because reflections degrade signal quality, structural return loss is an important measure of the consistency of a cable's impedance, especially for coaxial and high-frequency cable. Manufacturing the cable to tight, uniform tolerances minimizes the structural variations that cause reflections.
In commercial and industrial high-frequency cable, structural return loss reflects construction quality and affects signal performance. Recognizing the measure helps in understanding how cable uniformity is characterized.
