Dense wavelength-division multiplexing (DWDM) refers originally to optical signals multiplexed within the 1550 nm band so as to leverage the capabilities (and cost) of EDFAs, which are effective for wavelengths between approximately 1525–1565 nm (), or 1570–1610 nm ().

**Backscatter Level**: This indicates the amount of light scattered back towards the OTDR over the entire length of the fiber. measurements have simplified the development of new analytical and 'intelligent' testing capabilities. Reflectometers can now automatically perform link and feature recognition of the items in use, setting the optimal acquisition conditions (wavelengths and pulse duration), consolidating the. It operates similarly to an electronic time-domain reflectometer, but instead measures the optical properties of a fiber under test.
