SMF (LWPF)

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.

  • Low 1383nm attenuation for full utilization from 1265 to 1625nm
  • Fully compliant with (ITU-T G.652.D & G.657)
  • Small allowable bending diameter
  • Mechanically strippable coating for easy field application.
  • Compatible with any commercial optical devices.
  • Local area network systems
  • Long haul telecommunication
  • Closed circuit television system
  • Process control systems
