980 nm Polarization Maintaining Telecom Fiber

The breadth of Nufern’s range of Polarization Maintaining fibers is unrivaled. Designed for use from 980 to 1620 nm, these fibers are used in all PM applications for data and telecom. Nufern has applied its unique manufacturing facility and capabilities to this product area and has made substantial optical, mechanical and geometrical tolerance improvements. Furthermore, higher strength and fatigue failure resistance allows customers to achieve more uniform product results and to attain the highest possible manufacturing yields.
Applications
  • Lithium niobate modulators, PMD compensators
  • Raman gain modules
  • Pigtailing
Features & Benefits
  • Tight specifications — Highly deterministic results, highest product yield
  • High proof test — Low risk of mechanical handling failure
  • High fatigue failure resistance — Longest service life
