82 results about "Return loss" patented technology

In telecommunications, return loss is the loss of power in the signal returned/reflected by a discontinuity in a transmission line or optical fiber. This discontinuity can be a mismatch with the terminating load or with a device inserted in the line. It is usually expressed as a ratio in decibels (dB); RL(dB)=10log₁₀Pi/Pᵣ where RL(dB) is the return loss in dB, Pᵢ is the incident power and Pᵣ is the reflected power.
