Special Cutoff Wavelength Single-mode Fibre (SW-SMF)

YOFC SW-SMFs are optimized in the core parameters and waveguide stracture on the basis of ordinary single mode fibre. It takes advantage of PCVD process to realize operating wavelength of single-mode transmission under 980nm.
Applications
  • Special light source device
  • Pump tail fibre
  • Coupler
  • Compact optical device
Characteristics
  • Single cladding step profile
  • Good geometrical uniformity
  • Good mechanical properties
