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.
