Optical Return Loss in Fiber Optic Transmission Formulas

Optical Return Loss (ORL) is a measure of the amount of light reflected back toward the source in an optical communication system, such as in optical fibers or other optical components. And is denoted by ORL. Optical Return Loss is usually measured using the Decibel per Meter for Attenuation. Note that the value of Optical Return Loss is always positive.

FAQ

What is the Optical Return Loss?

Optical Return Loss (ORL) is a measure of the amount of light reflected back toward the source in an optical communication system, such as in optical fibers or other optical components. Optical Return Loss is usually measured using the Decibel per Meter for Attenuation. Note that the value of Optical Return Loss is always positive.

Can the Optical Return Loss be negative?

No, the Optical Return Loss, measured in Attenuation cannot be negative.

What unit is used to measure Optical Return Loss?

Optical Return Loss is usually measured using the Decibel per Meter[dB/m] for Attenuation. Neper per Meter[dB/m], Decibel per Kilometer[dB/m] are the few other units in which Optical Return Loss can be measured.
