Insertion loss: Are you positive it''s negative?
Return loss, which measures the amount of light reflected back toward the source, is also expressed in dBs and is always a positive number. A high return loss is a good thing and usually results in low
Where does optical return loss matter?
Optical return loss (ORL) is defined as the amount of light reflected back to the optical source and is expressed as a ratio of the power of the outgoing signal to the power of the reflected sig-nal.
Return loss calculator for testing fiber optic cables
The term Reflectance describes a single reflection in an optical assembly. Reflectance occurs at point discontinuities, for example connector interfaces, splice interfaces, etc. Typically, Return Loss is
Causes of Return Loss at Mated Single Mode Fiber Optic
The industry commonly uses the term Optical Return Loss when related to connectors and mated connections. This document uses Return Loss to describe the ratio of reflected light at mated
The FOA Reference For Fiber Optics
Long ago, most OLTS measured loss and displayed it as a negative number, but some companies who got into the fiber optic test equipment business from other test businesses arbitrarily decided to

Optical Return Loss Measurement
To ensure the proper performance of an optical transmission system, various parameters—such as attenuation and optical return loss (ORL)—must be within the acceptable tolerance levels of both the
Reflectance and Optical Return Loss (ORL) Measurement and Testing
Return loss for the entire fiber under test, including fiber backscatter and reflections and relative to the source pulse, is called Optical Return Loss (ORL). It is also given in units of dB, but always a positive
Measuring Reflectance or Return Loss
Below is a diagram of a typical setup for reflectance or return loss tests of connectors or patchcords per industry standards (TIA FOTP-107 or IEC 61300-3-6) using a light source and power meter.
Return loss
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.
