1550 nm Select Cutoff Single-Mode Fiber

Nufern’s 1550B-HP high-performance select cutoff bend insensitive single-mode fiber is optimized for use in small form factor active and passive components requiring tight bend radii. With a bend loss considerably lower than SMF-28™, 1550B-HP is ideal for the video leg in FTTH CWDM and applications such as smaller form factor C and Lband components and low NA planar waveguides.
Applications
  • FTTx components and modules
  • Compact C and L-band components
  • Low NA planar waveguides
  • Metro components
Features & Benefits
  • Optimized cutoff for 1550 nm wavelength — Extremely low bend loss
  • Tight mechanical and optical tolerances — high yield component manufacturing
  • Mode matched to SMF-28 — Low splice loss to standard fibers
  • High proof test for tighter bends — Critical for long-term reliability in tight bend applications
