Fibre Optic Tooling

 

FIBRE OPTIC CLEAVING TOOL

PRECISION - Mirror quality finish of cleaved fibre end face with less than 1.0 degree enface angle makes additional polishing unnecessary/  Ideally suited for "cleave & crimp" terminations.

VERSATILITY - Standard tool works on all 125 micron to 140 micron fibres; special tools are available for other fibre diameters.

ADJUSTABILITY - Can be adjusted for various fibre sizes and bare fibre quality cleaves without replacement

RELIABILITY - Gem-quality diamond scribe permits thousands of high quality cleaves without replacement.

SPEED - Fibre cleaving is performed in seconds.

DURABILITY - Outstanding durability due to rugged metal frame construction.

GHC100-1 (MIL-T-83523/10)
The standard cleaving tool is designed to work with all 125 micron or 140 micron optical fibres and most fibre optic connectors and splices.  Other versions of the tool are available for different fibre sizes.  The rugged carrying case contains the cleave tool assembly plus accessories and instructions to calibrate the tool for exceptionally clean fibre cleaves.  A precision lapped, gem-quality (diamond) scribe permits thousands of cleaves without the need for re-sharpening or replacement.  The stylus performs a scribing motion at the circumference of the fibre, while the fibre is under longitudinal tension.  A controlled break occurs with a mirror quality surface.  This makes additional fibre enface preparations, such as polishing, unnecessary.  End face angles are typically less than 1.0 degrees from perpendicular.

The cleave tool is a precision built tool utilizing a gem quality diamond cleaver.  If properly cared for, it will perform thousands of proper cleaves.  As with any precision tool, it is recommended that periodic calibration verification program be followed to assure that the tool is still cleaving properly.  Also, the diamond may become damaged, or worn, thereby requiring sharpening which in turn requires replacement and recalibration.

The following options are offered by DMC:

A.  Diamond Re-sharpening
remove the diamond clever from the tool and return it to DMC.  A replacement diamond will be sent by mail or regular UPS for a fixed charge including cost of shipping and handling.  The cost includes replacement of the diamond cleaver when it no longer can be re-sharpened (four to six sharpenings).  If the cleaver has been abused and the diamond cannot be re-sharpened, the customer will be advised as to replacement costs.  Contact DMC Sales for the details of this program.  NOTE:  Specialized equipment is necessary to reassemble, calibrate, and verify the accuracy of the tool.

B. Cleave Tool Return
The entire cleave tool may be returned to DMC prepaid for calibration and complete refurbishment.  The customer will be advised of the repair/service charge upon completion of an evaluation of the cleave tool.  Contact CRiMP-TECH Sales for the details of this program.
