Damping Mount / Dampening Device / Vibration Mount

We produce a variety of fiber optic cable fittings and our vibration damper for OPGW is one of our most popular products.

This vibration damper has two types. One is a preformed vibration damper. The other is the bolted vibration damper.

One is a preformed vibration damper
One is a preformed vibration damper
The other is the bolted vibration damper
The other is the bolted vibration damper

Recommended Configuration Table

No.	Span L (mm)	Number of damper for each span (pc)
1	100≤L＜250	2
2	250≤L＜500	4
3	500≤L＜750	6
4	750≤L＜1000	8

Features
Asymmetric type design: The basic principle of the vibration damper is to absorb dynamic energy with a frequency protection range from 5Hz-100Hz, and there are four resonant frequencies in this range.

Purposes
The damping mount effectively reduces vibration of the optical cable under many different factors, protecting the cable and its fittings.
