Abstract
A wide dynamic range optical receiver has low and high sensitivity signal channels for converting first and second portions of an optical input signal into voltage values representative of the various portions of the optical input signal. The voltage signals are converted into digital values by a converting means and a reconstruction is performed in a combining means to produce a digital output representative of the optical input signal. The wide dynamic range optical receiver may be used in an optical signal measurement instrument, such as an optical time domain reflectometer, where the optical return signal from a fiber under test is coupled to the wide dynamic range optical receiver in first and second portions with the first portion having an optical power level substantially less than the second portion.
