HFCL 2D Optical Fiber

HFCL 2D Optical Fiber is a single mode fiber that has low water peak attenuation and low optical losses over the entire bandwidth range. The two layers of high quality acrylate coating enhances the fiber reliability.

This fiber complies and exceeds the ITU-T G.652.D standards.

Applications

  • High speed transmission (DWDM and CWDM)
  • Metro networks
  • Access networks
  • CATV networks
