FSM-100 series

The Fujikura specialty fiber splicer FSM-100 series offers a host of innovative technologies to address the rapidly expanding splicing needs for factory,
manufacturing, laboratory and R&D applications. These capabilities is revolutionizing the way users splice various types of specialty fibers, LDFs, PMFs and so on.

Product Variation

Cladding diameter60 to 500μm60 to 1200μm
Heating areaNarrowWide
Electrode swing
PM Fiber splicing
End view fiber observation system

Sweep length0 to 10mm0 to 36mm


Optimal Plasma Zone Control

The patented “Split V-groove” and electrode systems create flexibility within the plasma zone.

Polarization Maintain fiber splicing(FSM-100P, FSN-100P+)

Three alignment methods for PM fibers
– Fast PANDA mode alignment by PAS system
– New IPA mode for alignment of all kinds of PM fibers
– EndView PM fiber alignment(FSM-100P+ only)

EndView observation system

Illumination is launched into cladding through fiber coating .
The lens captured the fiber end -face image directed by the mirror unit.

FSM-100M+ cannot automatically rotationally align PMFs.

Enhanced Sweep Plasma

Enhanced Power Calibrations 

The FSM-100 series provides three types of arc calibration methods for both 125μm fibers and LDFs.

Dual Splice Loss Estimation

FSM-100 series provides loss estimation methods using either cold or warm splice Images for accurate splice loss estimation.

USB, GPIB Communication

The splicer firmware can be upgraded via internet connection. Also, splice data upload/download is available via PC. The GPIB connection provides power meter feedback alignment capabilities.
