Abstract

Se describe un Reflectómetro de Dominio de Tiempo Óptico (OTDR) que prueba una fibra óptica al generar, transmitir y recibir señales de luz de una fibra óptica. El OTDR genera 5 señales de luz que tienen diferentes características y une estas señales de luz a una pista del OTDR. La retrodispersión y propiedades tales como rango dinámico afectan la calidad de la pista del OTDR.
