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.

As the pioneer and continuous innovator of fusion splicing technology in China, JILONG officially launches its landmark product – the 300T 6-motor trunk fusion splicer on the occasion of its 33rd anniversary. Purpose-built for the future of trunk networks, this professional-grade device integrates JILONG core patents and field-honed engineering expertise accumulated over 33 years in the fusion splicing field. It comprehensively redefines the industry standard for trunk-level fusion splicing across the board, from splicing precision, operation efficiency and equipment reliability to full-cycle service support.

Ⅰ. Precision Matched | Optimized for G654.E & Future Trunk Networks

The 300T fusion splicer is deeply optimized for the inherent characteristics of G654.E optical fiber from its fundamental architecture design. Through the precise coordination of 6-motor core alignment and intelligent algorithms, the dedicated G654.E splicing mode of the 300T can perfectly adapt to the large effective area and low attenuation characteristics of G654.E optical fiber, effectively reducing splicing loss.

JILONG Telecommunications' portfolio of over 100 invention patents is fully embodied in the 300T, with proprietary patented technologies empowering all three core steps of the fusion splicing process: in-process imaging, fiber advancement, and core alignment. Every single 300T unit undergoes rigorous trunk-grade calibration and testing prior to leaving the factory, ensuring it maintains laboratory-grade precision performance even in complex and dynamic field construction environments. This is not only a technological breakthrough, but also our unwavering commitment to upholding the highest standards of engineering quality.

Ⅱ. Efficiency Breakthrough: Proprietary 10s Heating Technology

The 300T is equipped with JILONG independently developed, patented 3D surround dual heating slots technology, enabling high-efficiency, uniform heating in just 10s. This innovative design breaks through the limitations of traditional single V-groove heating. Through 360° three-dimensional thermal field distribution, it ensures the heat shrink tube achieves uniform and stable heat shrinking performance in the shortest possible time.

Compared with conventional equipment, the heating mode of the 300T effectively eliminates the issues of secondary shrinkage or air bubble formation caused by uneven heating. In time-critical trunk network engineering projects, this efficiency improvement means more splicing joints can be completed per day, significantly shortening the overall project construction cycle.

Ⅲ. Rugged & Reliable: All-Metal Construction

The 300T features a precision-engineered all-metal body, with metal components accounting for over 65% of the total unit weight，a design that is virtually unprecedented in the industry. This all-metal construction not only delivers exceptional physical strength, but also forms an effective metal framework to shield the internal precision components from external interference.

The 300T has undergone comprehensive optimization and upgrading of its internal structural system. Critical components are fabricated from aviation-grade materials with a reinforced design, and all connection joints have received specialized treatment to ensure structural integrity and functional stability even under frequent transportation, handling, and harsh operating conditions.

Combined with a professional anti-drop design, the all-metal body enables the 300T to withstand accidental drops and impacts commonly encountered at construction sites, providing physical protection for the long-term reliable operation of the equipment.

Ⅳ. Ultra-Long Battery Life | 9000mAh High-Capacity Battery

Targeted at the characteristics of trunk network engineering, which often involves field operations with limited power access, the 300T is equipped with a 9000mAh ultra-large capacity lithium battery system. Having undergone tens of thousands of cycle tests in the laboratory and on-site field verification, this battery system can support 500 complete splicing and heating cycles when fully charged, meeting the demands of all-day high-intensity operation.

The battery module features a modular architecture with hot-swappable replacement functionality, enabling engineering teams to deploy spare batteries to achieve uninterrupted on-site operation. The battery has passed strict lifecycle performance testing, and maintains stable and consistent performance output even in extreme temperature conditions ranging from -20°C to 50°C.

Ⅴ. Jobsite Optimized | Comprehensive Humanized Design

The 300T’s detailed design is fully optimized for the practical requirements of on-site trunk engineering projects. Its tool-less detachable integrated SOC holder enables simple and fast optical fiber fixation; the tool-less electrode rod replacement design greatly reduces maintenance time; and the integrated portable cleaver operating platform realizes one-stop operation of cleaving, splicing, and heating.

The dual-layer cooling tray design can accommodate multiple spliced optical fibers simultaneously, improving operational continuity. The dual-operation mode, combining a 5-inch high-definition touchscreen and physical buttons, strikes a balance between operational convenience and reliability. All interfaces adopt a dust and water resistant design to adapt to various harsh operating environments.

Every design refinement originates from JILONG in-depth understanding of on-site trunk engineering environments, with the core goal of enabling technicians to complete their work with greater focus and efficiency, while minimizing the disruptions and burdens caused by equipment operation.

Ⅵ. Exclusive Assurance | 33rd Anniversary Edition Lifetime Service

The 300T, as a core product in JILONG 33rd Anniversary Commemorative Edition product series, is entitled to an exclusive service policy: lifetime complimentary maintenance service. All customers who purchase the 300T equipment will enjoy lifetime complimentary maintenance, complimentary calibration, and complimentary professional operation training.

JILONG 300T: Built for the Future Trunk Networks. It is far more than a fusion splicer, it is JILONG solemn commitment to the construction of next-generation communication networks to make every single fusion splice the most stable link in the foundation of the network, and carry forward the surging data tide of the digital era.
