In telecommunications, return loss is a measure in relative terms of the power of the signal reflected by a discontinuity in a transmission line or optical fiber.

Many electrical properties of networks of components (inductors, capacitors, resistors) may be expressed using S-parameters, such as gain, return loss, voltage standing wave ratio …

Return loss is caused by impedance mismatch between circuits. At microwave frequencies, the material properties as well as the dimensions of a network element play a significant role in …

In telecommunications, balance return loss is one of two things: A measure of the degree of balance between two impedances connected to two conjugate sides of a hybrid set, coil, …

Return loss is the measurement (in dB) of the amount of signal that is reflected back toward the transmitter. The reflection of the signal is caused by the variations of impedance in the …

Performance of optical fiber connectors can be quantified by insertion loss and return loss. Measurements of these parameters are now defined in IEC standard 61753-1.

Return loss, the ratio of the amplitude of the reflected wave to the amplitude of the incident wave Round-trip loss in laser physics refers to energy lost due to scattering or absorption

Non-zero main diagonal entries are related to return loss, and non-zero antidiagonal entries are related to isolation by similar expressions. Some authors define the port numbers with ports 3 …

In fiber optics and telecommunications, an index-matching material may be used in conjunction with pairs of mated connectors or with mechanical splices to reduce signal reflected in the …

The performance of an echo canceller is measured in echo return loss enhancement (ERLE), [3][9] which is the amount of additional signal loss applied by the echo canceller.
