Abstract

A waterproof special optical connector is an essential component for high-speed mobile communication. Also high reliability of IP67 level is required as it is used in outdoor environment. Optical connectors are a reliable communication method widely used in the IT industry, Display and Automobile industries. Currently, waterproof special optical connectors, which are mainly used in mobile communication base stations, are all dependent on overseas imports. The most widely used fastening structure shows a push-pull type and a bayonet type structure, and a rubber sealing structure is provided for waterproofing. We have designed and fabricated a waterproof special optical connector that reflects the requirements in the industrial field through the patent and structure analysis. The design of the waterproof type optical connector was designed by using commercial 3D design program and the reliability of design was secured through FEM analysis. In addition, the prototype was fabricated through mock-up processing using RP m/c and multiple QDM processing. In order to improve the working efficiency in the field, a waterproof type optical connector of push-pull fastening type was designed and manufactured. In addition, the reliability evaluation of insertion loss, reflection loss, waterproof performance, tensile strength, and malting test, which are basically required, was promoted. In the case of waterproof performance test, it was replaced by Air_leakage test, and tensile test was carried out by using a composite tester. The insertion loss and the return loss were measured through a light meter after the items were tested. The loss value of fabricated samples was good with loss value within 0.3dB of commercial product level. We have completed the design, prototype, and performance evaluation for the localization of the waterproof type optical connector which is applied to the Gigabit band repeater which is dependent on the whole import. The performance level was comparable to that of imported products. It is easy and simple to assemble through development of special type optical connector, satisfies high performance and high reliability of connector, and can minimize transmission loss of optical line. It is expected to improve product performance, increase productivity, and improve customer satisfaction by using convenience by securing technological competitiveness advantage in special type optical connector field by securing substantial core and source technology. Push-pull type waterproof connector for outdoor relay is a part used in special environment, so it does not seem to expand the market. However, dependence on import of special type optical connector is still high in the domestic environment leading the mining industry. From this research, it is hoped that the technology level for the development and manufacture of optical connectors for special purposes will be improved in domestic industry.
