Bend Insensitive g652d Single Mode Fiber

Flexi Bend

Flexi Bend is a single mode fiber that features zero water peak and low attenuation losses in the entire bandwidth range along with enhanced bend insensitivity. Other characteristics of this fiber are improved performance in macro bend loss, lower splice losses, and lesser dispersion losses leading to better transmission capabilities.

This fiber complies and exceeds the ITU – T G.652.D and ITU – T G.657.A1 standards.

Applications

  • Long-haul transmission
  • Metro networks
  • Mobile networks
  • Access networks
  • FTTX networks
