Analysis of insertion and return loss measurements in mechanical fiber optic connectors

This article analyzes fiber optic connectorizations used in data transmission. In this analysis, optical loss measurementsismade in mechanical connectors such as Insertion Loss (IL) and Return Loss (RL) based on the certification requirements for the commercialisation of telecommunications products by the National Telecommunications Agency (ANATEL) and international standards. In addition to the fundamental theoretical argument, we performed an evaluation of field-mounted connectors from ten different manufacturers sold in Brazil. These measurements were made based on two groups of tests: climatic and mechanical tests, in which the optical loss values are measured both initially and during the tests, thus depending on the requirements of the standards.
