Product Description

SC Single mode Plug-in Fixed Fiber Optic Attenuator, Male/Female

This SC/APC and SC/UPC plug-in fixed fiber optic attenuator is designed to reduce optical power levels within singlemode fiber systems. With a male-to-female connector configuration and precise fixed attenuation values (1–25dB), it is ideal for balancing signal strength in FTTH, CATV, and telecom applications. Available in both UPC (flat polish) and APC (angled polish) versions to meet different return loss requirements.
