Optical power meters are used to measure absolute optical power or the relative loss of optical power through a section of optical fiber, and in optical fiber systems, measuring optical power is fundamental. Optical light source refers to a light source whose output parameters such as optical power and wavelength remain stable and unchanged. It is often combined with an optical power meter to measure fiber loss. Visual fault locator is a kind of visual light source, also known as light pen and light-passing pen, which is used for optical fiber identificalion, fault location of.
