Signal fire AI-20/AI-30 fusion splicer applies multiple of the latest patented technologies of Signal fire, and adopts a more advanced central processing unit, more advanced algorithms, and higher precision cameras. Especially, the AI-30 fiber core is clearer and more visible, and the fusion loss and stability are better. It is fully capable of longer distance mainline fiber optic cable fusion splicing projects.The weight of bare machine,tool case and complete set of accessories only 4.5kg, size of tool case is 25.5cmx16.5cmx23cm. In such a compact and compact situation, the combination design of workbench and bench has been achieved simultaneously. 1 second startup, 6 seconds rapid fusion, 15 seconds heating, 5-inch color touchscreen, 320x magnification, 7800mAh large capacity lithium battery can fuse and heat 240 cores, still performs well in harsh environments such as high altitude, dry, and cold.


Fusion splicer series model

Signal Fire optical fiber fusion splicer AI-6A/6C/7C/8C/9/12 use the latest core alignment technology with auto focus and six motors, it is a new generation of fiber fusion splicer. It is fully qualified with 100 km trunk construction, FTTH project, security monitoring and other fiber cable splicing projects. The machine uses industrial quad-core CPU, fast response, is currently one of the fastest fiber splicing machine in the market; with 5-inch color touchscreen, the operation is simple and intuitively; and up to 320 times focus magnifications, making it is very easy to observe the fiber with naked eyes. 6s speed core alignment splicing, 15s heating, the working efficiency increased by 50% compared to ordinary splicing machines. Large capacity lithium battery, fully charged state can splice & heat 260 fibers, also the splicer machine can charge the phone, to solve your trouble when your phone has no power at outdoor working. Under the conditions of rigorous testing, the performance is still outstanding; toolbox is small, exquisite, durable, and with unique bench design. The design of operating platform reflects the humanistic care; unique lighting design, it is convenient for night construction or repair. Screen brightness is adjustable and it is convenient for outdoor sunshine environment operation. The core parts are using imported brands, aviation metal body material with exquisite details. With the combination of advanced technology and design, the new generation of optical fiber fusion splicer will bring you a reliable and comfortable user experience.

Craftsmanship spirit

accumulate steadily to reach the top of the industry

Industrial CPU, fast response, It is one of the fastest optical fiber welding machines on the market
Use 5-inch color touchscreen, simple and intuitive operation graphics
Up to 320x focusing magnification makes it easy to observe the core with the naked eye

AI-12
Trunk line optical fiber fusion splicer

From the signal station on the summit of Mount Everest to the construction
site in the South American rainforest, and then to the private network
communication in the Gobi oilfield in the Middle East, the AI-12 has witnessed
the most extreme working environments for humans. It is not merely a 6-motor
fusion splicer, but also a pioneer in bridging the digital divide. The core alignment
accuracy of 0.05μm is our ultimate respect for every fiber optic signal.

Three golden standards

1.The fiber core is "visible"
2."True Fiber Core" Display
3."Accurate" core alignment

Can see clearly
accurately and splice steadily

Splice once and 'become' once, Almost zero rework,
Work harder and earn more money,
and pass the inspection of the main line once!

320X magnification

Automatic fiber type identification
The fiber core can be seen very clearly
One thousandth of a hair gap can be recognized at a glance! Accurate, visible!

Make every information
artery run robustly

Fully independent and self-controllable
