Ensaios de perda por inserção e por retorno em conectorizações mecânicas em fibra óptica

Abstract

This work presents an understanding about the execution of tests on fiber optic connectorizations used in data transmission. In this study, optical loss measurements is made in mechanical connectors such as Insertion Loss (IL) and Return Loss (RL) based. The test methodology was based on the certification requirements for the commercialization of telecommunications products by the National Telecommunications Agency (ANATEL) and international standards of the International Electrotechnical Commission (IEC). In addition to the fundamental theoretical argument, we performed an evaluation of field-mounted connectors from ten different manufacturers sold in Brazil. The tests were carried out at the light source wavelength of 1550 nm 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. Furthermore, It was carried out through the facilities and equipments from the Laboratory for Testing Telecommunications Equipment (LTET) at the Federal University of Itajubá (UNIFEI).
