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.eturn loss is the negative of the magnitude of the reflection coefficient in dB. Since power is proportional to the square of the voltage, return loss is given by, where the vertical bars indicate magnitude.
A loss instead of a profit is described as a negative return. Rate of return is a profit on an investment over a period of time, expressed as a proportion of the original investment. The time period is typically a year, in which case the rate of return is referred to as annual return. To compare returns over time periods of different lengths on an equal basis, it is useful to convert each return into an annual equivalent rate of return, or annualised return.
