YOFC Bare Fiber G.652D Low Water Peak Single mode Fibre


China YOFC  Low Water Peak Single mode Fiber G.652D 

Descriptions: 

   YOFC FullBand® low water peak dispersion unshifted Single-mode fibre is designed specially for optical transmission systems operating over the entire wavelength window from 1260 nm to 1625 nm. By suppressing the water peak that occurs near 1383 nm in conventional single mode fibre due to hydroxyl (OH-) ions absorption, FullBand® fibre is able to open E-band (1360-1460nm) for operation, and consequently provides 100 nm more usable wavelengths.


 Features: 

  • Designed for operation over the full optical spectrum from 1260- 1625 nm, which provides 509% more

  • usable wavelengths and hence the transmission capacity is increased

  • Outstanding optical performance supporting high-speed transmission technologies such as DWDM and CWDM

  • Being compatible with existing 1310 nm equipment

  • Good protection and excellent strip force stability

  • Accurate geometrical parameters that insure low splicing loss and high splicing eficiency
