Abstract
An apparatus for monitoring optical equipment in an optical circuit is disclosed in which the apparatus may include an optical device situated to receive an optical input signal and to reflect a portion of the energy of the received optical input signal, thereby providing a reflected input signal; a first photodiode located along a path of the reflected input signal, and operable to receive optical energy from the reflected optical input signal and from ambient optical power; a second photodiode located substantially outside the reflection path of the optical input signal; and means for calculating a magnitude of a power level of the optical input signal from values of outputs from the first and second photodiodes.
