本文介绍的光缆连接器是中性的,可同时接通两路光信号,并且可以现场清洗以保证低损耗的重复连接。文中叙述了该连接器的结构形式、设计原理及制造方法,并列出了测试结果。为了准直光信号,采用光束扩展透镜。采用了这些渐变折射率的透镜使连接器在连接端面处能安装可折卸的、便于清洗的保护玻璃。该连接器采用一种特殊的调整工艺,使两芯的、中性的连接器具有良好的互换性,所测得的互换后的损耗最大值为2.06dB。该连接器寿命大于2500次,抗拉强度超过150kg,并且具有密封及耐腐蚀等优点。
This article describes the cable connector is neutral, can be connected to two optical signals at the same time, and can be cleaned on site to ensure low-loss repeated connections. The article describes the structure of the connector, design principles and manufacturing methods, and lists the test results. To collimate the light signal, a beam expansion lens is used. The use of these graded index lenses allows the connector to be fitted with removable, easy-to-clean protective glass at the connection end face. The connector uses a special adjustment process, so that the two-core, neutral connector with good interchangeability, the maximum loss measured after the exchange of 2.06dB. The connector life of more than 2500 times, more than 150kg tensile strength, and has the advantages of sealing and corrosion resistance.
