1、Good interchangeability, repeatability, and abrasion resistance, possess low insertion loss, the average additional loss is 0.2dB, come with high return loss, more than 1000 insertion and removal times 2、Widely used in optical fiber distribution frame (ODF) optical fiber communication network, optical fiber broadband access network, optical fiber CATV, optical fiber instrument meter, optical fiber local area network, etc., possess stable and reliable performance 3、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 adopted for good optical performance and high mechanical stability 4、The isolation effect is good, effectively suppressing the noise of the ground loop, so that the signal field and the main control terminal are electrically isolated effectively 5、Using high - density engineering plastic material, strong, wear - resistant and not easy to deform, safe and secure
