Brand New SC/UPC 3dB Female-Female Fixed Fiber Optical Attenuator
The Brand New SC/UPC 3dB Female-Female Fixed Fiber Optical Attenuator is a precision-engineered passive component designed to reduce the power level of optical signals in fiber optic networks. Featuring SC/UPC (Ultra Physical Contact) connectors, this fixed attenuator delivers a stable 3dB attenuation, ideal for balancing signal strength and preventing receiver saturation in short-distance or high-power links.
With female-to-female coupling, it’s easy to insert between existing SC patch cords or devices without any modification. Perfect for use in FTTx, CATV, data centers, and telecom transmission networks, this high-reliability attenuator ensures long-term performance with minimal insertion loss and excellent return loss.
