HFCL A1 Optical Fiber

HFCL A1 Optical Fiber is a single mode fiber that is bend insensitive and has low water peak attenuation. This fiber offers reduced macro bend loss, lower splice losses, and lesser dispersion losses leading to better transmission capabilities.

This fiber complies and exceeds the ITU-T G.657.A1 standards.

Applications

  • Long-haul transmission
  • Metro networks
  • Mobile backhaul networks
  • Access networks
  • FTTX networks
  • Micro cables
  • Drop cables
