The loss of the coated fiber optic connector is negative
Optical return loss is the amount of light that is reflected back to the source, this reflected light is measured at each connector and splice at each point over the entire fiber link. Fiber optics connector loss refers to the signal attenuation that occurs when two fibers are connected, often caused by imperfections in the connector or the way the fibers are aligned. It is expressed in negative dB and used to describe any process that causes light to change direction in fiber and return to the source. 10GBASE-LRM) from running on a network. A high return loss. By MARK MULLINS, Fluke Networks -- Insertion loss, or the loss of signal that happens along the length of a fiber-optic link, is expressed in dBs and should always be a positive number. But it can be negative (which isn't a good thing). Losses can be introduced by various means such as intrinsic material absorption, scattering, bending, connector loss and more.
