Coractive’s attenuation optical fiber (ATN) products have been specifically designed to provide flat attenuation over the widest wavelength range possible. Wideband uniform attenuation ensures full compatibility with current and future DWDM, CATV and other telecom systems. The ATN-FBS has a wide attenuation range (<0.4 dB/cm), perfect for manufacturing attenuators used in undersea telecom applications.
