g657 a1 bending resilience single-mode optical fiber

HFCL A1 190 Optical Fiber is a single mode fiber that combines the properties of HFCL A1 optical fiber with reduced diameter. It is of specific use in cases where more number of fiber count needs to be packed in the cable. Bending resilience maintains the attenuation performance after cabling leading to improved transmission properties. It also has advantage of being fully compatible with existing networks.

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

Applications

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