What is the difference between RWP (Reduced Water Peak) and ZWP (Zero Water Peak) Fiber?

February 12, 2020

Zero Water Peak (ZWP) is an industry term for an optical fiber with improved attenuation over Reduced Water Peak (RWP) optical fiber at the 1383 nm wavelength and overall water peak band (1360 – 1460 nm).

There is no industry standard for ZWP optical fiber and both RWP and ZWP optical fibers meet the requirements of the ITU G.652.D full spectrum optical fiber specification.

There is no measurable impact to loss budgets for original and higher-performance networks.

Superior Essex offers ZWP optical fiber upon customer request.
