Splicing with the wrong magnetic fiber holder can throw your fusion splicer out of alignment, increase splice loss, and cost you valuable time in the field.
In this video, we take a detailed look at SPARC Detachable Single Fiber, Fiber Holders from Jonard Tools and explain why it’s critical to match the holder to your specific fusion splicer — whether you’re working on Core, Clad, or Ribbon machines.
These precision-engineered magnetic holders are designed to hold one fiber at a time, but single fiber machines and ribbon machines require different holders, even when splicing a single fiber on a ribbon platform. Mixing them can lead to poor splice quality and long-term calibration issues.
Key Features:
• Precision-machined alignment for exact fiber positioning
• Swappable design for seamless transfer between cleaver and splicer
• Magnetic retention to keep fibers steady during splicing
• Matched left and right pairs, ready to use out of the box
Holder Compatibility Breakdown:
“S” Part Numbers = Single Fiber Machines (Core & Clad)
FH-900S/2 – 900 micron jacketed fiber
FH-200/250S/2 – 200–250 micron bare fiber
Non-“S” Part Numbers = Ribbon Machines (Single Fiber Mode)
FH-900/2 – 900 micron single fiber on ribbon platform
FH-200/250/2 – 200–250 micron single fiber on ribbon platform
⚠️ Using the wrong holder — even if it looks similar — can misalign magnetic clamps, increase splice loss, and compromise machine calibration.
Bottom line: cleaner alignment means better splices — but only when the holder matches the machine it was engineered for.
