The industry's first zero water peak single-mode fiber for reliable full-spectrum performance.


AllWave® Zero Water Peak (ZWP) Single-Mode Optical Fiber is a full-spectrum fiber designed for optical transmission systems operating over the entire wavelength range from 1260 nm to 1625 nm. Developed by OFS, the fiber is made with a patented manufacturing process that permanently removes the water peak defect to ensure low and stable loss performance in the 1400 nm band and over the lifetime of the cable. AllWave ZWP Fiber offers the lowest loss of all commercial low water peak fibers in the industry for access and FTTX networks.

With the availability of electronics throughout the spectrum, including the previously unused 1360 – 1460 nm “E” band, AllWave ZWP Fiber provides additional capacity in the network.

Product Description:

AllWave ZWP Fiber is ideally designed for use in metropolitan, local, and access networks due to its superior specifications – low optical loss across the entire wavelength range from 1260 to 1625 nm, tightest available geometry, low splice loss, and low polarization mode dispersion (PMD).  Combined with complete compatibility with embedded fiber base, these features provide ultimate network design flexibility and enable cost-effective solutions to help maximize return on investment.

  • Low optical loss across the entire spectrum from 1260 – 1625 nm, providing a 50 percent increase in usable spectrum, enabling 16-channel CWDM as well as DWDM support
  • A patented manufacturing technology that permanently removes the water peak defect for low, stable loss performance in the 1400 nm band
  • Long-term attenuation reliability due to the use of high purity synthetic silica
  • Ultra-low fiber PMD allows speed and distance upgrades
  • The industry’s tightest geometric control for lowest splice loss and improved connectorization performance
  • Macrobend performance superior to the G.652D standard

AllWave ZWP Fiber provides outstanding performance and design freedom for fiber management systems in:
  • Metro access
  • Metro edge
  • Local access
  • FTTX
  • Campus backbones
  • Long haul
