Vibration Damper for OPGW

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.
