The Differences Between OTDR & Optical Power Meter
While an optical power meter tests the received optical power, an optical time-domain reflectometer (OTDR) provides length and loss by utilizing backscatter reflection. Why does that

Reflectometers are instruments for measuring the reflectance (or reflectivity) of objects, i. Other general purpose light power measuring devices are usually called radiometers, photometers, laser power. Reflectance (which has also been called "back reflection" or optical return loss) of a connection is the amount of light that is reflected back up the fiber toward the source by light reflections off the interface of the polished end surface of the mated connectors and air. As shown in the figures above, the OCWR Testing setup for reflectance or return loss tests of connectors or passive fiber components per industry standards (TIA FOTP-107 or IEC 61300-3-6) using a light source.
