Optical return loss vs reflectance

WebA new fiber pigtailed optical receiver design using a single gradient-index rod lens with a beveled exit face achieved a broadband optical return loss of >65 dB, which was limited by the diffuse reflection from the photodetector front surface. By contrast the optical return loss for a receiver with an unbeveled lens exit face and an on-axis optical path was limited … Webconnections and greater losses. This measurement is the same as return loss, which is expressed as a positive value to indicate how much signal was lost by comparing input power to output power versus reflectance that compares output power to the amount of light reflected. For both reflectance and return loss, the
