Optowire Vibration Damper OFR-3 (18~28mm)

Optowire Vibration Damper OFR-3 is a reliable anti-vibration fitting developed for aerial optical cable and conductor protection systems. Designed for cable diameters from 18 to 28 mm, the OFR-3 effectively suppresses wind-induced aeolian vibration, helping to reduce fatigue damage and extend cable service life. Its optimized dual-mass hammer design delivers stable damping performance across a broad frequency range, ensuring reliable operation in demanding outdoor environments. Manufactured from durable galvanized steel, the damper provides excellent corrosion resistance, mechanical strength, and long-term stability. The OFR-3 is widely used in ADSS, OPGW, and power transmission networks to improve cable reliability and infrastructure safety.
