Furukawa FITEL S183 Fusion Splicer

In addition to splicing standard fibers, the FITEL S183 can splice polarization-maintaining fibers while preserving polarization, faster than any other fusion splicer in the world! The new rotation mechanism of the S183PM enables precise rotation around the fiber’s longitudinal axis while maintaining a firm grip and a stable position.

  • Splicing PM fibers with polarization maintained
  • Splicing specialty fibers (EDF, PCF, HighΔ)
  • Precise rotation around the fiber’s longitudinal axis
  • Splicing fibers with diameters from 80 to 500 microns
  • Lowest PANDA crosstalk: -40 dB

FITEL S183 – fusion splicer for PM polarization-maintaining and specialty fibers

FITEL S183PM II is a specialized fusion splicer designed for laboratories, optical component manufacturers, and R&D facilities. Its key advantage is splicing polarization-maintaining (PM) fibers while preserving polarization at the lowest possible crosstalk value — faster and more precisely than any other FITEL model.

The S183 supports not only standard fibers (SM, MM, DSF, NZDSF) but the entire range of specialty fibers: PANDA and BOW-TIE polarization-maintaining fibers, erbium-doped fibers (EDF), large-cladding-diameter fibers (up to 500 µm), photonic crystal fibers (PCF), and high-delta HighΔ fibers. It automatically recognizes the fiber type and selects splicing parameters without the need to change V-grooves or holders.

⇒ splicing PM fibers (polarization-maintaining fibers)

⇒ splicing certain types of microstructured fibers
⇒ high strength fiber splicing
⇒ splicing specialty fibers
⇒ splicing fibers with diameters from 80 to 500 microns
⇒ accepted cladding diameter from 100 to 1200 microns

Key feature: splicing PM fibers with polarization maintained

Splicing polarization-maintaining fibers requires precise alignment of the polarization axes of both fibers being joined. The S183 performs this fully automatically, thanks to an innovative rotation mechanism:

  • Automatic analysis of a new PANDA fiber and creation of an optimal rotation program
  • Precise rotation around the fiber’s longitudinal axis while maintaining a firm grip
  • Automatic release of the holder after splicing — eliminates fiber twisting when the holder returns
  • PANDA crosstalk: -40 dB (0.6° axis deviation) — best-in-class accuracy
  • PM fiber splicing time (cladding clamping): 35 seconds

Who is the FITEL S183 for?

The S183 is a laboratory fusion splicer — it is not intended for field installations. Its natural environment is:

  • Manufacturing of optical components and modules (couplers, isolators, PM circulators)
  • R&D laboratories and technical universities
  • Splicing specialty fibers: EDF (EDFA amplifiers), photonic crystal fibers (PCF), large-diameter fibers (up to 500 µm)
  • Dissimilar fiber splicing with automatic parameter matching

If you are looking for a fusion splicer for FTTH, LAN, or PON network installations — we recommend the field model: FITEL S179+
