The typical specification range of return loss of a fiber connector is -15 dB to -60 dB. Return loss is also known as reflection loss. It indicates the amount of signal reflected back to the transmitting end. Return loss refers to the power loss caused by the reflection of part of the signal back to the signal source during transmission due to the discontinuity of the transmission. Insertion loss, also known as attenuation, is the loss of optical power that occurs when light passes through a fiber optic connector. It is caused by factors such as misalignment, air gaps, and imperfections in the connector components. The lower the insertion loss, the better the performance of.
