1、The insertion loss is low, and the optical fibers are connected by the adapter through the internal open sleeve. Provide various shapes of performance adapters to ensure the connection between the optical fiber jumpers 2、Possess good repeatability, good interplugging, widely used in optical fiber distribution frame (ODF) optical fiber communication network, optical fiber broadband access network, optical fiber CATA, optical fiber instrument meter, optical fiber local area network, etc., with stable and reliable performance 3、The return loss is large, the conversion adapter can be connected to different types of optical fiber jumper interfaces, and the for APC dual connection can increase the density 4、The isolation effect is good, the signal field and the main control terminal are effectively isolated electrically to prevent the main control system from accidentally breaking 5、Advanced grinding equipment makes the center of the optical fiber grinding and deviating. The zirconia sleeve with high temperature resistance, acid resistance and high hardness (high density) is used, which has good optical performance and high mechanical stability 6、Has good mutual insertion performance, good flame retardancy, high temperature resistance and environmental protection, meeting environmental protection requirements, possess high impact resistance and beautiful appearance
