7.1. Top Inserts
The GPX4000LZ CO

Laser Glass Processor requires fiber holder inserts to be placed in the fiber holding blocks
in order to clamp the fibers during the splicing process. Fiber holder top inserts sit in the lid of the fiber holding
blocks and come in a variety of groove sizes. They can be used to clamp the cladding, coating, or buffer of a fiber.
The top inserts and bottom inserts can be paired in a variety of combinations to accommodate all fiber sizes
compatible with the glass processors, as shown in Figure 56. Multiple combinations of top and bottom inserts may
be required to accommodate all sizes of fiber to be spliced.
There are two types of top inserts. The standard top inserts (Item #'s starting with VHA) come in single-sided and
double-sided versions; the specified fiber diameter (in µm) is engraved on the part. These top inserts cannot be
used for end-view imaging. They are, however, compatible with the FPS300 Fiber Preparation Station, LDC Series
of Fiber Cleavers, and LFS4100 Fusion Splicer. For end-view imaging and alignment, an insert with an indent for
LED illumination (VHB00 or VHB05) is required. This mode of operation allows for alignment of the cores of
polarization-maintaining, eccentric-core, and micro-structured specialty fibers. These LED illumination inserts are
also compatible with the LFS4100 Fusion Splicer.
