Physical characteristics of the fiber, increased signal levels, amplification nonlinearity, inconsistent or 'dirty' connector end-faces as well as components on the fiber such as splices and connector terminations can all be a factor that cause increased attenuation. Attenuation (loss and back reflection) can be measured by using an Optical Power Meter and an Optical Light Source, or an Integrated Power Meter / Light Source for bidirectional testing (pair needed), or an Optical Time Domain Reflectometer (OTDR) and a Handheld Power Meter. (It is recommended to utilize a fiber reference jumper for all scenarios). When testing large fiber counts, data storage and the ability to download the information to a computer, is essential.
