How to Use the Fiber Adapter (Included with the Thin Fiber
Units)
①Turn the adapter cap fully counterclockwise to
unlock, and then align the ends of the adapter
pipe and fiber. Turn the cap fully clockwise to
lock the adapter.
②Cut the fiber to the desired length, using the fiber
cutter included with the free-cut fiber unit.
When inserted correctly, the
fiber insertion indicators will
turn from white to black.
