WebEn el caso de los OTDR, un dato que debemos suministrarle es el IOR, para que este pueda estimar la Velocidad de propagación de la señal a través del medio que va a medir. Les recomiendo la lectura de Fenómenos de la Luz. ¡Si alguno de nuestros lectores tiene sugerencias, consultas sobre este tema, añadirlo en un comentario y les responderé! WebThe OTDR measurement range refers to the maximum distance from OTDR test data . The selection of this parameter determines the size of the sampling resolution. The best measuring range is between 1.5 ~ 2 times the length of the fiber to be tested. Since the backscattered light signal is extremely weak, statistical averaging is generally used to ...
