Abstract

"DISPOSITIVO DE TENSãO DE FIBRA óTICA, PROCESSO PARA CONTROLAR A TENSãO APLICADA A UMA FIBRA óTICA AO LONGO DE UM TRAJETO DE AVANçO DE UMA FIBRA óTICA, E, SISTEMA DE PROCESSAMENTO DE FIBRA óTICA". Dispositivo de tensão de fibra ótica, recebendo em sua entrada uma fibra ótica (35) de um dispositivo de tração (37) e capaz de prover a fibra ótica de sua saída para um dispositivo (40) para armazenar a fibra. O dispositivo de tensão (1) inclui pelo menos uma polia fixa (32) sobre a qual a fibra ótica (35) é enrolada, por um certo comprimento pelo menos, e pelo menos uma polia móvel (9) sobre a qual a fibra ótica (35) é enrolada, por um certo comprimento pelo menos. Um dispositivo para medir a tensão aplicada à fibra e um dispositivo motorizado (24, 26, 5, 7) para mover a polia móvel (9) interagem um com o outro para controlar a distância (Dp) entre os eixos (33, 20) das polias (32, 9) de tal modo a automaticamente manter a tensão aplicada à fibra essencialmente constante."FIBER OPTICAL TENSION DEVICE, PROCESS TO CONTROL THE VOLTAGE APPLIED TO AN OPTICAL FIBER ALONG A FIBER OPTIC ADVANCING PATH, AND, FIBER OPTICAL PROCESSING SYSTEM". Fiber optic tension device, receiving an optical fiber (35) at its entrance from a traction device (37) and capable of providing the optical fiber of its output to a device (40) to store the fiber. The tensioning device (1) includes at least one fixed pulley (32) on which the optical fiber (35) is wound, for at least a certain length, and at least one movable pulley (9) on which the optical fiber is wound. (35) is rolled, for a certain length at least. A device for measuring the tension applied to the fiber and a motorized device (24, 26, 5, 7) for moving the movable pulley (9) interact with each other to control the distance (Dp) between the axes (33, 20) of the pulleys (32, 9) in such a way as to automatically maintain the tension applied to the fiber essentially constant.
