Overview
The ST/UPC Multimode Male-Female Attenuator is a precision optical component designed to reduce the power level of a fiber optic signal by a calibrated amount. This device is specifically engineered for 62.5/125µm multimode fiber systems, ensuring accurate signal attenuation for testing or link power balancing applications.
Constructed with a rugged ST-style housing, this attenuator provides a stable physical connection between existing patch cables and equipment ports. It is suitable for deployment in data centers, telecommunications networks, and laboratory testing environments where signal strength management is required to prevent receiver saturation.
