FFS2000 Series Chapter 6: Fiber Preparation
Page 34 TTN047338-D02
The thermo-mechanical stripping method uses heat to soften the acrylate coating. A heating element is
incorporated in the bottom V-groove insert at the stripping station. The heating element is kept at a low
background temperature at all times, which for some fibers (such as SMF-28) is sufficient to strip the coating
almost immediately. Other fibers require a high temperature “boost”, which rapidly increases the coating
temperature such that it can be stripped with minimal pull force. The boost time is typically less than 5 seconds.
Some fibers may also require a presoaking in acetone to soften the coating prior to thermo-mechanical stripping.
The recommended procedures for thermo-mechanically stripping various fiber types are shown in the table below.

Soaking Station Preparation (Chemo-Mechanical Only)
Make sure the solvent is “topped up.” It should be approximately 1/8" to 1/4" below the lip of the solvent container.
Stripping Station Preparation
Clean the stripping station with the soft toothbrush (provided) or the optional vacuum cleaning system, keeping
your free hand as a ‘shield’ around the rear of the open Cleave Lid, to prevent debris being thrown up onto other
parts of the machine. Remove any stripped coating or other particles from the Cleave Inserts and around the
Stripper Blades. It is important that these surfaces are kept clean, or subsequent Strip or Cleave operations may
be less effective until these surfaces are cleaned.
WARNING
Do NOT clean the V-groove insert with solvent when the vacuum is turned on. The solvent will be
drawn into the vacuum system and will cause internal damage. If the V-Groove appears to be
damaged, replace the inserts.
6.2.2. Soaking Procedure (Chemo-Mechanical Only)
Place the right FHB with the preloaded fiber on the right side dunking jig at the soaking station. Inserting the FHB
pins into the dunking jig will activate the internal vacuum to the FHB V-groove. With the fiber secured in the FHB,
tilt the end of the dunking jig to immerse the fiber into the soaking station. Make sure that the FHB Cleave Lever is
in the forward (down) position to immerse the fiber deeper into the solvent, as shown in Figure 38.
