Signal Fire AI-8 Fusion Splicer

The latest Core Alignment Fusion Splicer from Signal Fire the AI-8. £1542.00 + vat




Core alignment technology with auto focus and six motors, it is a new generation of fibre fusion splicer. It is fully qualified with 100 km trunk construction, FTTH project, security monitoring and other fibre cable splicing projects. The machine uses industrial quad-core CPU, fast response, is currently one of the fastest fibre splicing machine in the market; with 5-inch 800 x 480 high-resolution screen, the operation is simple and intuitively; and up to 300 times focus magnifications,making it very easy to observe the fibre with naked eyes. 6 seconds speed core alignment splicing, 15 seconds heating, the working efficiency increased by 50% compared to ordinary splicing machines.

The fusion splicer comes with all the tools to carry out a splice joint. The Toolbox comes with a stool to facilitate the construction workers acting as a work bench.

High-capacity lithium battery, continuous splicing and heating about 200 times.
