Best Fit
a. These inserts have two grooves, one on each side, that each accommodate a different range of fiber sizes, except for the VHA00, which
has a flat surface on one side that can be used to clamp the smallest fiber sizes.
b. These bottom inserts have vacuum holes to aid in aligning small fibers when used with the LDC401 and LDC401A large-
diameter fiber cleavers.
c. These are transfer inserts. When used with the VHT1 transfer clamp, they allow the fiber to be transferred between stripping, cleaning,
cleaving, splicing, and tapering stations without losing registration of the fiber tip location relative to the edges of the fiber holding block.
Here are instructions for using the charts on this page.
1. First, select the Bottom Insert that matches your fiber size most closely.
Example: For an Ø800 µm fiber, the VHD750 insert is the closest match, since it is only 50 µm smaller.
2. On the chart below, look to the right of your chosen Bottom Insert. Select a compatible Top Insert
based on the fiber diameter size range shown in each cell.
Example: For the Ø800 µm example fiber from step 1, the green cell is in the 750 µm groove column for
the VHA05 Top Insert which has two grooves. The numbers listed in the green cell indicate that this
combination of Inserts is good for fibers from 728 to 963 µm in diameter. Our Ø800 µm fiber is within this
range, so this is a good choice. There are several other options as well that will accommodate an Ø800 µm
