TECHNICAL NOTE: Measuring OTDR Reflectance and ORL
Typically, reflectance measurements are limited to ~-70dB. The OTDR generally tests ORL by calculating the total of all the light reflected from reflective events plus the total backscatter from the
The FOA Reference For Fiber Optics
Typical reflectance measurements require a large dynamic range, since reflectance is small for most current types of connectors as shown in the table below.
