Back in the 1990s, China’s fiber fusion splicer market was entirely dominated by imported brands, with unit prices exceeding $30,000 To break this foreign‑brand monopoly, the predecessor of Nanjing JILONG, Kelong Communication Technology, was founded in 1993.
We independently developed and manufactured the first‑generation domestic fusion splicer KL‑100, priced at only half of its Japanese‑made counterparts.
Since then, JILONG has pioneered independent R&D and driven the growth of China’s fusion splicer industry for more than 30 years.
Today, JILONG has built a core‑competitive team combining in‑house R&D specialists and global‑based international sales experts.Our strong R&D capability delivers continuous technical iteration, supported by large‑scale production capacity, numerous patents and a full‑range product portfolio.Our worldwide sales team provides localized service and market insight for partners across every continent.
As a leading supplier of optical‑communication products and solutions, we have participated in China’s 4G and 5G network construction.
We keep empowering global telecommunication infrastructure with reliable, cost‑effective optical‑fiber technologies.
