Fiber Holder Top Inserts (Two Required)

9.1. Fiber Holder Inserts
Fiber Holder Inserts, which are designed to hold various sized fibers within the Cleaver, must be purchased
separately. The Bottom Inserts have V-grooves to hold the fiber, while the Top Inserts each feature a recessed, flat
surface that clamps the fiber against the V-groove in the Bottom Insert. Each top and Bottom Insert is sold
individually, as the fiber diameter clamped by the left and right holding blocks may not be the same. Two Top Inserts
and two Bottom Inserts are required to operate the Cleaver. Available Inserts are described below, and the Insert
Selection Guide in Section 9.1 should be used to select the appropriate Inserts for each holding block.
Top Inserts
The table below summarizes the top Fiber Holder Inserts that are available from Thorlabs.

Bottom Inserts
Bottom Inserts are available in three varieties:
•
The VHD Series of Fiber Holder Inserts are single-sided, have holes for vacuum suction (used on other
Vytran products, such as the GPX family of splicers), and can accommodate fiber sizes up to Ø1.047 mm.
•
The VHF Series of Fiber Holder Transfer Inserts are designed to work with the VHT1 Transfer Clamps that
aid in moving the fiber between compatible Vytran stations while maintaining coarse alignment. They are
also single-sided and also have vacuum holes.
•
The VHE Series of Fiber Holder Inserts are for fibers with claddings >Ø773 µm. They may be single- or
dual-sided.

This side of the VHA00 is flat to provide additional clamping force for fibers with very small diameters.
