30-year-old JILONG fiber splicing, fiber optic splicer, OTDR, splicing machine - Nanjing JILONG

Focus on optical communication for 30+ years

In the early 1990s, the domestic field of optical fiber fusion splicer was blank. At that time, the domestic market was monopolized by imported splicer brands, in order to solve this dilemma, in 1993, the predecessor of Nanjing JILONG -- Kelong Communication Technology Co., LTD was established, which opened the door of independent research and development of domestic fusion machine.
Over 30+ years of research and development, JILONG Communications has developed into a global professional company in optical communication products and solutions.
