Coractive’s attenuation optical fiber (ATN) products have been specifically designed to provide flat attenuation. Wideband uniform attenuation ensures full compatibility with current and future DWDM, CATV and other telecom systems. The ATN-FBL has a wide attenuation range (<0.4 dB/cm) for manufacturing patchcord-type attenuators used in telecommunications.
