Automatic test stand for glass optical fiber with straight tip connector in digital transmission

摘要

An automatic tester was developed for optical fiber transmission system over its performance parameters during optical fiber lifetime. For this purpose, we have designed a signal conditioning module for fiber optic waveguides. For sending and receiving data over optical fiber we have used a typical TTL adapter built with MC10H116 (a triple differential amplifier designed for use in sensing differential signals over long lines). A microcontroller- based system is used to measure the correspondence between a sending and receiving of a string sequence over a glass optical fiber probes. The measurements prove the "aging" of the fibers, with deterioration of the speed parameter.
