7.3.2. Cleaning the Fiber Holding Block Insert
Debris in the fiber holding block v-grooves may interfere with fiber positioning. The v-grooves should therefore be
cleaned carefully, using a soft brush moistened with acetone
.
7.3.3. Adjusting the Transfer Insert Block
The block at the end of the transfer insert can be adjusted to accommodate fibers of slightly different diameter
(see Figure 48 for details). To do this, one must first loosen the two set screws in the back of the block. One then
adjusts the set screw in the bottom of the block. If going to a smaller diameter fiber, one turns the screw
clockwise. If going to a larger fiber, one turns the screw counterclockwise. The side of the block should remain
flush with the end of the insert. Once the correct block height has been reached, the two setscrews in the back of
the block should be re-tightened.
