Abstract

Спосіб управління процесом виготовлення оптичного волокна включає вимірювання в процесі витягування поперечних коливань волокна, аналіз безлічі складових частот поперечних коливань і визначення основної частоти. Винахід належить до оптичних світловодних волокон, зокрема, до способу контролю натягнення волокна при витягуванні.
