    FFS2000 Series Chapter 6: Fiber Preparation 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.

    This causes an increase in silica deposits on the fiber, which can’t be completely removed during the fire polish step. The result will be decreased splice strengths. Thorlabs personnel can advise on the correct methods of performing splices to avoid this issue.
