Low Water Peak Single Mode Optical Fiber

Product Detail Information


Mercury's LWPF is designed to provide improved performance across the full wavelength region form 1265 to 1625nm. Mercury's LWPF fully meets ITU-T G.652 and is available for use in loose tube cable, ribbon and other cable designs. Mercury use ultra-pure materials based on silica, so this optical fiber has excellent optical and mechanical performance.

Features & Benefits

  • Low attenuation at 1383nm for full utilization from 1265 to 1625nm
  • Low transmission loss and great repeater spacing
  • Outstanding geometrical properties for low splice loss
  • Minimum bending loss at operation wavelength region
  • Mechanically strippable coating for easy field application
  • Compatible with any commercial optical devices
