Fusion Splicer Related Products

Optical Fiber Cleaver

The CT52 also allows for a reduced cleave length of 8 mm on 900 μm jacketed fibers and as short as 3 mm on 250 μm and 400 μm coated fibers.
The CT58 cleaver is designed for cleaving silica fibers with 80 μm cladding.

Active Blade Management Technology

1. Automatic Blade Rotation

The fusion splicer and CT52/58 fiber cleaver have wireless data connectivity. This capability allows automatic cleaver blade rotation when the splicer judges the blade is worn.

Motorized blade

2. Blade Life Management

The fusion splicer indicates the remaining blade life and also informs the user when a blade height change is required.

User Friendly

1. Easy Maintenance

The CT52/58 fiber cleaver has a user replaceable blade and rubber clamps, so there’s no need to send the device to a service center for blade or clamp replacement.

2. EASY ACCESS & Longer Stripped Fibers

The CT52/58 li opens 100 degrees to offer easy access and can accommodate longer stripped fibers than previous models

3. Single Action Operation

The CT52/58 cleaves and collects the fiber scrap with a single press action.

*1:Measured with an interferometer at room temperature, not with a splicer. A new blade was used to cleave the single fibers. The average cleave angle changes depending on the environmental conditions, blade condition, operating method, and cleanliness.
*2:The blade life changes depending on the environmental conditions, operating method, and the fiber type cleaved.
