inserts; they allow for a single fiber to be transferred between the Vytran FPS300 Fiber Preparation Station,
LDC400 Series of Fiber Cleavers, and LFS4100 Splicer without loss of positional reference. For example, a fiber
can be placed in a transfer insert and cleaved using the LDC400 cleaver. Then, the entire transfer insert can be
placed in the LFS4100, and it will already be roughly aligned for splicing. This process works because the transfer
inserts are precisely located within each Vytran system and the VHT1 magnetic lid on the transfer inserts
prevents axial movement of the fiber during transport. These transfer inserts include vacuum holes that provide a
small suction force to hold the fiber in place.

3.5.5. Splice Head
The splice head employs a filament assembly that can be changed if a different filament size is desired. This
assembly is held down by two filament clamps. In addition to holding down the filament assembly, the filament
clamps also serve to limit the influx of room air into the splicing area, as they have protrusions that cover most of
the filament cavity.

3.5.6. Filament Assembly
Thorlabs supplies filaments as part of a filament assembly, as shown in the Figure 8. These assemblies contain a
graphite or iridium filament within a protective shroud. One filament assembly (sold separately) is required to
operate the LFS4100 fusion splicer.
