LFS4100 Chapter 3: Description

3.5.2. Fiber Holding Blocks

The fiber holding blocks are used for holding, positioning, and moving the fibers during the splice process
implemented on the LFS4100. Fiber alignment can be performed using either the edges of the fibers or their
cores. Standard fibers require only an XY alignment, while specialty fibers may require both XY alignment and
rotational alignment. The rotation function permits each fiber to be rotated by up to 200 degrees. This is used to
align the stress members of PM fiber, the cores of eccentric-core fiber, and the surface features of non-circular
fiber.

3.5.3. Fiber Holding Block Inserts

The LFS4100 fusion splicer requires fiber holder inserts to be placed in the fiber holding blocks in order to clamp
the fibers during the splicing process. A top and bottom insert (sold separately) is required for each of the two
fiber holding blocks. A variety of fiber holder inserts are available for different fiber diameters. To see the available
fiber holder inserts, see the selection chart in Chapter 8. In addition to the standard sizes, custom inserts may be
specially designed for various applications. Contact Thorlabs for more information.

3.5.4. Fiber Holder Transfer Inserts (Bottom Inserts for Fibers ≤Ø1047 µm)
There are two types of bottom inserts that are compatible with the LFS4100 fusion splicer. The bottom inserts for
fibers with cladding or buffer diameters up to 1.047 mm (indicated with Item #'s starting with VHF) are transfer
