Editor's Note:As optical fiber communication advances toward ultra-high-speed transmission, the G.654.E fiber has emerged as a core choice for next-generation trunk networks thanks to its ultra-low loss and large effective area. Nevertheless, its stringent splicing requirements have long been regarded as the touchstone for high-end splicing technology.With 34 years of in-depth dedication to the optical communication industry, JILONG breaks the bottleneck with exquisite craftsmanship and sets a new benchmark. It takes the lead in launching the 300T G.654.E Trunk Fusion Splicer, becoming the first established domestic manufacturer capable of stable splicing for G.654.E fiber.

Driven by the explosive growth of 5G, artificial intelligence, the Internet of Things, high-definition video and other applications, G.654.E fiber is being deployed on a large scale in national trunk line. Riding this trend and drawing on 34 years of profound technological accumulation, JILONG pioneered the launch of the 300T G.654.E Trunk Fusion Splicer.

Equipped with a self-developed 6-Motor core alignment system and intelligent algorithms, the device comes standard with a dedicated G.654.E splicing mode. Its measured splicing loss is stably controlled within 0.03dB, matching imported high-end models in core performance.

As a pioneer and industry innovator in China’s optical fiber splicing technology, JILONG holds over 100 invention patents accumulated over 34 years. The 300T fully embodies the essence of these technologies, with patented innovations covering the three core splicing processes: fiber core imaging, fiber propulsion and elastic core adjusting.

Benefiting from its solid technological heritage of 34 years, the 300T is on par with imported high-end models in key parameters including splicing loss, splicing time, heating efficiency and motor configuration. Adopting innovative technology such as 3D surround dual heating slots, the 300T achieves 6s splicing and 10s heating time, greatly boosting operational efficiency. Its 6-Motor configuration paired with high-precision core alignment realizes nano-level core adjustment, successfully overcoming the technical difficulties of G.654.E fiber splicing.

In terms of hardware, the 300T features an all-metal body with dust-proof, drop-proof and waterproof capabilities, maintaining stable and reliable performance even in extreme environments. The built-in 9000mAh large-capacity battery supports approximately 500 splicing and heating cycles per full charge, meeting the demands of all-day field operations.

In terms of intelligence, the 300T is equipped with a 5-inch touchscreen and a Type-C charging interface, significantly lowering the operation threshold.

As one of JILONG’s 33rd anniversary flagship products, the 300T also enjoys lifetime free service. Boasting industry-leading performance in splicing speed, splicing quality, motor configuration and after-sales service, it fully covers high-reliability application scenarios such as national trunk network, data center interconnects and submarine cable projects.

JILONG is a time-honored and well-known enterprise in the industry. As early as 1993, its R&D team broke foreign technological monopolies and launched KL-100, China’s first domestically produced optical fiber fusion splicer. The brand "JILONG" is recognized as a Famous Trademark of Jiangsu Province. The launch of the 300T once again highlights JILONG’s leading position in high-end splicing technology.
