*1 - The first heating after turning on the power can be longer than the usual heating time.

*2 - The number of splicing and heating cycles the machine can produce using a fully charged brand new battery at room temperature of 20C, semi-auto mode for splicing 125m cladding fibre and regular mode for heating. Depending on the condition of the battery and operation environment, the number can vary.

  • 3SAE Thermal Stripper ACC-01-0059

  • The 3SAE Thermal Strippers are compact, easy-to-use fiber stripping units designed to thermo-mechanically remove coatings from optical fibers. The High Strength Adjustable Thermal Stripper supports optical fibers with cladding diameters from 30 m to 1000 m, with coating diameters up to 1200 m.

    This includes standard 250 m, 400 m, and 900 m coated fibers. Adjustable temperature and time settings allow it to adapt to stripping a variety of different coatings and cladding sizes.

  • Northlab Procleave LD CL-01-01000

  • The NorthLab ProCleave LD is a fibre cleaver for large diameter fibers up to 550 m. The ProCleave LD is specifically designed for use in production lines where ease-of-use, process speed and a high production yield is crucial.

    The ProCleave LD can facilitate FITEL fibre holders and generates very flat end-faces and low cleave angles (typical <0.5) with a high repeatability. The simple and robust design ensures low maintenance and a trouble-free use.
