1 Cable Preparation Tools and Techniques
A. Show the correct and safe usage of cable preparation tools
Cable Knife
Kevlar shears/snips
Tube Ring Tool
T strippers
B. Tight Buffer Cables - Preparations for termination of jumpers and system cables
Measure and then Ring the cable jacket accordingly
Remove the out jacket to expose fibers and inner materials
Cut the Kevlar, nylon tape and any strength members
If necessary, ground the cable using recommended cable manufactures
procedures.
C. Breakout & Fan Out Kits
Determine the type of kit if necessary
Prepare and clean the cable to match
Install fibers to kit
Label as necessary
D. Connector Assembly
Determine connector type to be installed
Slide the connector boot onto each fiber
Remove the fiber coating with proper stripping tools
Clean the exposed fiber with alcohol pad
Apply epoxy to fiber and connector body
Insert fiber through connector & ferrule and let epoxy cure
Cleave fiber from ferrule end with hand scribe tool
Perform hand polishing techniques until fiber is flush with ferrule
Inspect polished fiber end with connector view scope
Determine polish quality for acceptance
