As communication networks keep evolving toward longer transmission distances and larger capacity, fiber fusion splicers must deliver consistent splicing performance while withstanding long-term, high-intensity field operations.

Jilong has refreshed its 300T product lineup to build a brand-new portfolio for long-haul networks with two models: the 300T, featuring an all-metal body and built for conventional long-haul trunk projects; and the 300T+, compatible with G.654.E fiber for low-loss long-haul trunk scenarios. One safeguards trunk quality, the other embraces the G.654.E future.

1. 300T: 120km All-Metal Long-Haul Fusion Splicer

The Jilong 300T adopts core alignment technology to ensure reliable splicing results. Equipped with 3D surround Dual-heating slots and a tool-Less disassembly SOC holder, it completes fiber heating in under 10 seconds for easier maintenance.

Designed for prolonged outdoor deployment, the 300T sports an all-metal construction and a 9000mAh Li-ion battery. A single full charge supports approximately 500 splicing-and-heating cycles, balancing ruggedness and nonstop operation capacity.

Whether for cross-region deployment or long-haul trunk fiber jointing, the 300T delivers stability, durability and cost-effectiveness, making it a dependable workhorse for long-term field use.

2. 300T+: 120km All-Metal G.654.E Long-Haul Fusion Splicer

With the deep expansion of 5G infrastructure, low-loss, large-effective-area fibers such as G.654.E have gained traction for selected long-distance, high-capacity trunk applications.

Built upon the 300T platform, Jilong introduces the new 300T+ fusion splicer. Retaining the all-metal construction and long battery life, the 300T+ integrates fiber core visualization and intelligent algorithms optimized for G.654.E fiber characteristics, with a dedicated G.654.E splicing mode. Lab test results show its G.654.E splicing loss consistently outperforms national standards.

For contractors working on G.654.E deployments or those looking to get ahead of upcoming low-loss long-haul fiber adoption, the 300T+ is a forward-looking solution.

3. Precise Matching, Select Based on Your Needs

Quick summary: Pick the 300T if you need a robust, durable primary splicer. Choose the 300T+ to future-proof your setup for G.654.E and other low-loss fiber applications.

4. The 300T Series: Connecting the Present, Building for the Future

As Jilong’s flagship line of trunk fusion splicers, the 300T series iterates continuously based on real-world field requirements. This lineup refresh represents Jilong’s refined segmentation of long-haul application scenarios.

The 300T targets conventional long-haul trunk construction. Its all-metal construction, long runtime and strong value proposition make it a reliable daily workhorse. The 300T+ serves low-loss G.654.E long-haul trunk projects, delivering reduced splicing loss and forward-ready features to meet demands for premium trunk networks and next-generation infrastructure.

From access networks and metropolitan networks to long-distance trunks, Jilong keeps expanding its fiber splicing portfolio so every user can find equipment tailored to their job site.

Additional "+" series product roadmaps will be announced gradually. Stay tuned.
