Coupling Single-mode Fibre (CSF)

YOFC single-mode coupled fibres are particularly developed for fused taper coupler applications. Fabricated with patented Plasma Chemical Vapor Deposition (PCVD) process, YOFC coupler fibre offers excellent geometric and optical consistency. Special waveguide design and excellent drawing process ensure high mechanical strength and insensitivity to bending. This fibre is also an ideal option for applications in near-infrared communication devices and sensors.
Applications
  • Optical fibre couplers, splitters and combiners
  • Component fibre for optical fibre lasers, EDFAs and DWDM system
  • Pump laser pigtails
  • Gratings
  • Fibre sensors and gyroscope
  • Low-loss fused optical devices for C/L band applications
Characteristics
  • Tight geometric control
  • Superior mechanical protection by dual acrylate coating system
  • Ultra-low bending loss
  • Low attenuation
  • Low insertion loss
  • Low splice loss
  • Excellent consistency and reliability
