Nanjing Jilong Optical Fiber Communication Co., Ltd. (hereinafter referred to as Jilong Communication/Nanjing Jilong) started in 1993 and has a brand history of 30 years. Jilong is a domestic high-tech enterprise and a professional supplier of optical communication products and solutions. It has been We will develop and form four major product systems, mainly "fiber fusion splicing, OTDR, measuring instruments, and fiber optic tools", aiming to provide global users with a complete series of optical communication solutions.

Dating back to the 1990s, all the welding machines on the domestic market were foreign brands, and the price was around 300,000 yuan. In 1993, the founding team of Jilong broke the monopoly of foreign welding technology and took the lead in developing and launching the domestic fiber welding machine KL-100, taking the key step of domestic welding machine from scratch. Its price is only half that of Japanese brands. Later, various models of fiber splicing machines were launched one after another, and the product cost continued to decrease, and the scale of Jilong Company continued to grow. Not only that, Jilong Communications can also be called the "Whampoa Military Academy in the domestic splicing machine industry", with many inventions from Jilong The open sharing of patents and utility model patents has promoted the rapid rise of domestic welding machines, and has also made great contributions to the domestic optical advancement and copper withdrawal, FTTH optical fiber entry, domestic 4G and 5G network construction and the development of the optical communication industry. .

In 2012, the construction of Jilong Industrial Park was completed and put into use. The park covers an area of ​​21 mu, with a total construction area of ​​more than 14,000 square meters. It has a standardized office building, a modern production workshop, an industry-leading laboratory, an intelligent warehousing system, etc. The company has more than 150 employees, including 4 engineers with high professional titles, 11 master's degree or above, 86 technical management talents of various types, and bachelor's degree accounts for more than 60% of the company's number.

In the glorious years of thirty years, Jilong has set new records again and again, and has obtained more than 155 related patents. It is listed companies in the field of domestic welding machine, domestic welding machine is the first manufacturer to export overseas, certified by domestic high-tech enterprises, and participated in the drafting. The new national standard for fiber splicing machines "GB/T 17570-2019 General Specifications for fiber splicing machines", the laboratory was recognized as the "Nanjing Communication Equipment Manufacturing Engineering Technology Research Center"... The company has also passed the ISO9001 quality system certification, and its products have passed the EU CE safety certification, Rosh certification. At present, Jilong Communications has formed a cross-regional business pattern with Nanjing as its management headquarters, Shanghai as its R&D center, and Bengbu as its production base, and has strong independent R&D and production capabilities.

As a pioneer of the domestic fiber splicing machine brand, Jilong Communications has developed and produced fully automatic fiber splicing machine, software and hardware design, both have independent intellectual property rights, among which high-quality models such as KL-360T and 280T adopt Jilong's new independent model The core alignment technology developed can clearly see the optical fiber core during the welding process, and the application of this technology effectively achieves ultra-low loss welding.

Not only that, Jilong Communications is also making efforts in the OTDR field. Since the first generation of OTDR--KL-6210 was launched in 2010, Jilong has been continuously developing OTDRs in depth, striving to make domestic OTDRs with excellent performance. In 2022, the second-generation OTDR of Jilong's single-machine multi-powered and intelligent KL-6200 will be launched, allowing domestic OTDRs to be comparable to imported machines. In 2024, the third-generation OTDR of Jilong, the high-precision all-round KL-6300, will be launched.

Today, Jilong’s product services have covered the fields of optical fiber communication construction, measurement and maintenance, inspection and cleaning, greatly reducing customer selection costs. At present, Jilong products are widely used in fiber optic network engineering such as communications, radio and television, railways, petrochemicals, and scientific research institutes. Their products and services cover Europe, North America, Australia, South America and other regions.
