CT-52 Durable, simple optical fibre cleaver

UOS: Piece
  • Blade life of 60,000 cleaves
  • Six different possible cleave lengths
  • Convenient and easy adjustment and operation
  • Bluetooth connectivity


The CT-52 provides unprecedented durability and simplistic maintenance unseen with any other cleaver. The CT-52’s blade life is easily managed and maximized via Bluetooth connection with a convenient smartphone app. Because the CT-52 incorporates motorised push-button blade rotation and a convenient thumbwheel for blade height adjustment, routine cleaver adjustments are easy and convenient.

The 16-position blade delivers 60,000 cleaves, which means extended intervals between blade replacement. Although the CT-52 is designed for use with either Fujikura FH-100 or FH-70 series fibre holders, it can also be used with the optional adapter plate to eliminate the need for fibre holders, if desired. When utilized with the optional spacers for the cleaver and RS series thermal stripper, the CT-52 makes are six different cleave lengths possible. The CT52 also allows for a reduced cleave length of 8mm on 900μm jacketed fibres and as short as 3mm on 250μm and 400μm coated fibres.

Splice+ is a smartphone application that works in cooperation with Fujikura's splicers, cleavers and ribbon fibre strippers which have Bluetooth capability.


Automatic blade rotation

The fusion splicer and CT-52 fibre cleaver has wireless data connectivity which allows automatic cleaver blade rotation when the splicer judges the blade is worn.

Blade life management

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

Easy maintenance

The CT-52 has a user replaceable blade and rubber clamps, so there’s no need to send the device to a service centre for blade or clamp replacement.

Easy access and longer stripped fibres

The CT-52 opens 100 degrees to offer easy access and can accommodate longer stripped fibres than previous models.

Single action operation

The CT-52 cleaves and collects the fibre scrap with a single press action.

1The optical fibre type, the blade condition or the operating environment may affect the cleaving angle. Since the measuring device has been changed from an interference microscope to a fusion splicer, this specification value is now higher than that of the previous model (CT-30).

2The Bluetooth wireless connection of this product is not guaranteed to work with all 3 smartphones or other devices. Bluetooth is a registered trdemark of Bluetooth SIG, Inc.
