ACTIVE ARRANGEMENT METHOD OF OPTICAL MODULE AND APPARATUS THEREOF

摘要

PURPOSE: An active arrangement method of an optical module and an apparatus thereof are provided which enable active arrangement of the optical module. CONSTITUTION: A light emitting part(2) generates an AC optical signal having a fixed frequency by modulating a light source having output characteristics of a continuous wave. A light receiving part(4) converts the AC optical signal generated in the light emitting part into a current signal, and converts the converted current signal into a voltage signal having a fixed amplitude. An amplifier(6) amplifies the voltage signal converted in the light receiving part. And a peak detector(8) detects an amplitude of the voltage signal amplified in the amplifier and then converts it into a DC signal.
