Thin end cap pigtail / Connectors & Terminations

End Cap are ideal for photonics crystal, micro-structured and hollow-core fibers (PM or non PM). Specify and/or provide us the fiber; we realize your connector assembly: ferrule, FC, SMA or others.

Thin end cap pigtail summary

The fibers on which the end caps are spliced must have a clad diameter close to 125, 250 or 400µm. 5 examples of fiber compatibility:

  • HCF : Hollow-Core Photonic Bandgap Fibers
  • ESM : Endlessly Single Mode Fibers
  • SUP : Supercontinuum Photonic Crystal Fibers
  • ARF : Anti-Resonant Hollow-Core Fibers
  • LMA : Large Mode Area Fibers
