Due to the innovative fiber design, TrueWave REACH fiber has the lowest dispersion slope, best dispersion compensation over the widest bandwidth, lowest water peak attenuation, highest Raman gain efficiency and lowest system polarization mode dispersion (PMD) in the industry.
Low water peak attenuation for NZ-DSFs enables opportunities with emerging technologies such as Raman amplification and 40 Gb/s transmission.
The manufacture of LWPF requires the careful control of moisture levels at every step in the fabrication and post treatment of the fiber so that the water peak attenuation is kept below 0.
