The JDS Uniphase OAB1552-20FA0 is a fixed optical attenuator that reduces optical signal power by 20 dB. Designed for optical networking and telecommunications, it manages signal strength to prevent receiver saturation and protects sensitive components from overload. The unit operates across dual telecommunications wavelengths with excellent return loss performance and handles continuous-wave input up to 100 mW, making it suitable for field deployment in demanding environments.
