Abstract

Patente de Invenção para <B>"ATENUADOR óTICO VARIáVEL DE ACOPLADOR DE FIBRA"<D>. Um atenuador ótico variável acoplado de fibra inclui um acoplador de fibra ótica montado através de uma bucha de material de módulo inferior (2) em um encerramento protetor (4) com uma extremidade presa e outra extremidade livre (1). A extremidade livre (1) do acoplador é deflexionada por um mecanismo motorizado. O mecanismo inclui um motor de escalonamento elétrico (10), um eixo mecânico (9) que proporciona movimento excêntrico, e um componente de suporte/deflexão conectado com o acoplador em uma cadeia cinemática, que proporciona deflexão lateral da extremidade livre do acoplador. Os parâmetros estrutural e de material dos membros de cadeia cinemática são estabelecidos para satisfazer condições de compensação térmica para o encerramento que envolve esta cadeia. A extremidade livre do acoplador é equipada com uma luva tendo uma superfície polida esférica posicionada em contato com o componente de deflexão. O encerramento (4) é equipado com um dispositivo de compensação térmica (14) posicionado em série entre o encerramento (4) e as fibras óticas.
