Using the Cleaver with Wirepath SSF™ Fiber Cable

Q:  Which slot do I position the fiber in for cleaving?
A: 

To cleave Wirepath brand fiber (3mm diameter with soft peel coating) or 

2mm fiber, use the rear slot. For 250 and 900um fibers, use either the 

front or rear slot, whichever one gives the cleanest cut.
Note:  Positioning  the  fiber  perpendicular  (90°)  to  the  cleaver  wheel  is 

very important for obtaining quality cleaves/end faces. Use the flip-down 

holder (

) to help ensure the fiber is held in place during cleaving.

Q:  How do I prep the fiber?
A: 

Always begin a termination with about 2 inches of coated fiber exposed at 

the end of the cable to ensure the best possible cleave. A certain amount 

of colored soft peel coating must be left between the cable jacket and the 

end of the fiber. See connector instructions for dimensions.
Use your fingernails to remove the coating, then run your fingers on all 

sides of the glass to ensure complete removal. Or, if desired, use a fiber 

wipe (not necessary because the optical glass is coated/protected).
Never attempt to cleave the fiber with the colored soft peel coating still on 

the glass because it will dirty the cleaving wheel. If this occurs, clean the 

wheel using a cotton swab soaked in alcohol.

Q:  The tool will not cleave the fiber correctly – what is the solution?
A: 

After  positioning  the  fiber,  close  the  flip-down  holder  (

), then close 

the cleaver lid. Then, use your thumb to quickly push the cleaver slide  

lever (

).  Sometimes  pushing  too  slowly  will  cause  the  fiber  to  not 

cleave. You are not trying to “snap it”, just a steady push. With just a bit 

of practice the fiber should successfully cleave.

Also, make sure you are closing the “lid/handle” of the cleaver completely 

so that the magnet holds it shut. The fiber also needs to extend out the 

right side into the trash collector so that once cleaved, the waste glass 

can be caught in the collector.

If you continue having issues, see the cleaver wheel adjustment 
instructions, also included with the kit.
