Description

OPTONEST specialty optical fibers are fabricated for WDM attenuator application with flat attenuation properties. The attenuation fibers have the potential to offer high reliability and stable input power endurance. OPTONEST attenuation fibers are designed to be used for plug and in-line types attenuators covering from 1240nm to 1600nm with 0.1~30 dB.
