In the digital networking era, massive overhead and underground optical cables form an extensive "neural network" for communications. Cable routing inspection and fault detection constitute fundamental routine work throughout optical cable deployment and daily maintenance. Conventional cable tracing methods suffer from lengthy operation and low efficiency when deployed in harsh field environments and over long-distance fiber routes; worse still, stripping cable jackets or cutting fiber cores commonly causes secondary damage to the cabling system.

In the field of optical communication testing, every improvement in accuracy and efficiency translates to lower project risks and greater confidence in decision-making.JILONG officially launches its 4.3-inch premium instrument series, delivering a new-generation measurement experience for optical fiber link acceptance and optical cable construction.

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.

With the full-scale implementation of China's national "East-to-West Computing Capacity Diversion" strategy, G654.E ultra-low-loss (ULL) optical fiber is gradually emerging as the dominant choice for trunk network construction. For next-generation trunk projects that require longer transmission distances, stricter loss performance requirements, and adaptability to more complex construction environments, the telecommunications industry has set unprecedented high standards for fusion splicing equipment.
