Product Overview


PFP's single-mode double clad coupler fiber is designed for 1550 nm amplifier modules utilizing higher power multimode pumps. With a core designed to match SMF-28? and an inner cladding glass-on-glass structure optimized to accept multimode pump energy, this fiber is ideal for the signal leg in high power CATV couplers.

  • CATV pump/signal couplers
  • Laser delivery/fluorescence
Features & Benefits
  • Single-mode core - Low splice loss to SMF
  • Glass-on-glass double clad structure - Compatible with Nufern Power Delivery Fibers
  • Exceptional geometric uniformity and core/clad concentricity - Superior fiber diameter tolerances
