OPTICAL PREAMPLIFIER AND RECEIVER ASSEMBLY, AND METHOD OF OPTIMIZING SENSITIVITY.

摘要

The invention relates to a preamplifier and optical receiver assembly. BR/ It relates to a preamplifier and optical receiver assembly, in which the preamplifier is an optical amplifier (11) having an automatic gain adjustment, so that the optical signal output from the preamplifier, applied to the input of the receiver (13), is kept at a constant value. Preferably, the optical amplifier (11) is a pumped fiber amplifier doped with erbium, with automatic gain adjustment by feedback. BR/ Application to fiber optic telecommunications systems.
