LC Fiber Optic Attenuator 5dB LC/UPC | Single-Mode Optical Adapter | High-Temp Stable Attenuator

LC/UPC 5dB Fiber Optic Attenuator – Precision Signal Control for Optical Networks

This LC fiber optic attenuator (5 dB, LC/UPC) is designed to accurately reduce optical signal power in single-mode fiber (SMF) networks, ensuring optimal performance and protecting sensitive optical receivers. Ideal for networking, telecommunications, data centers, CATV, and FTTH applications, this attenuator provides stable and consistent attenuation even in high-temperature environments.

Featuring a compact LC male-to-female adapter design, the attenuator installs easily between LC patch cords and optical equipment without additional tools. High-quality ceramic ferrules and precision manufacturing deliver low insertion loss, excellent return loss, and long-term reliability.
