Vibration Damper/Armour Rod
■ Introduction:
The company offers a 4D series of anti-vibration hammer tuning fork design for Stockbridge, multi-resonance sound damping devices, mainly used for weakening and fragmentation of fiber optic cable due to aerolian vibration generated by the impact energy.

■ Configuration for OPGW Dampers:
OPGW dampers are typically used based on the cable diameter and span. The recommended quantity of dampers per span is as follows:
For cables with a diameter of less than 12 mm:
- 100–300 m span: 2 dampers
- 300–600 m span: 4 dampers
- 600–900 m span: 6 dampers
For cables with a diameter between 12 and 22 mm:
- 100–350 m span: 2 dampers
- 350–700 m span: 4 dampers
- 700–1000 m span: 6 dampers
- 1000–1200 m span: 8 dampers
■ Configuration for ADSS Dampers:
ADSS dampers are similarly installed based on cable diameter and span length. The recommended number of dampers per span is:
For cables with a diameter of less than 12 mm:
- 100–250 m span: 1 damper
- 250–450 m span: 2 dampers
- 450–700 m span: 4 dampers
For cables with a diameter between 12 and 22 mm:
- 100–250 m span: 1 damper
- 250–500 m span: 2 dampers
- 500–800 m span: 4 dampers
- 800–1000 m span: 6 dampers
Note: For critical spans, the number of dampers should be adjusted for safety, either by increasing or decreasing the quantity.
