FullBand® G.652.D Low Water Peak Single-Mode Fiber for Advanced Communication

FullBand G.652.D Low Water Peak Single-Mode Fiber

The FullBand® low water peak dispersion unshifted single-mode fibre is engineered specifically for advanced optical transmission systems operating over the entire wavelength window from 1260 nm to 1625 nm. By suppressing the water peak that traditionally occurs near 1383 nm due to hydroxyl (OH-) ions absorption, the FullBand® fibre opens the E-band (1360-1460nm) for seamless operation, consequently providing 100 nm more usable wavelengths.

Thanks to its broad usable optical spectrum and outstanding optical performance, this single-mode fiber complies with and exceeds the stringent requirements of the ITU-T Recommendation G.652.D and the IEC 60793-2-50 type B1.3 specifications. It is the optimum choice supporting various high-speed applications such as Ethernet, Internet Protocol (IP), Asynchronous Transfer Mode (ATM), Synchronous Optical Network (SONET), and Wavelength Division Multiplexing (WDM).

Key Characteristics & Advantages

  • Designed for operation over the full optical spectrum from 1260-1625 nm, providing 50% more usable wavelengths.
  • Outstanding optical performance supporting high-speed transmission technologies such as DWDM and CWDM.
  • Fully compatible with existing 1310 nm equipment for easy integration.
  • Accurate geometrical parameters ensuring extremely low splicing loss and high splicing efficiency.
