Figure-8 Aerial Cable Support Clamp 8-1
The 8-1 suspends and supports figure-8 fibre optic cable at intermediate points on outdoor FTTX routes.
Features
- For round cable profiles
- Specified messenger diameter: 4–8 mm
- Specified span range: 30–70 m
- Minimum breaking load: 2 kN
Application
The 8-1 secures optical cable on outdoor telecommunications supports, including routes between buildings and industrial structures. Its groove body, supporting frame and rod form an integrated cable clamp. Internal grooves or surface patterns increase friction to resist loosening or disengagement. Length can be specified to suit customer requirements. The technical specification lists galvanized steel and aluminium construction.

General test method
Ultimate tensile strength testing evaluates a product’s capacity to withstand mechanical pulling loads. Opposing tensile forces are applied to a specimen until it deforms or fails. The resulting measurements provide information on elongation, yield point, tensile strength and ultimate strength.
Tensile testing is used to assess pole-line suspension clamps, preformed guy grips, ADSS dead-end fittings, stainless steel bands, FTTH drop clamps and tension clamps.
For overhead optical cables and their accessories, endurance testing combines mechanical and thermal loading with oscillating stresses. The applicable test values depend on the requirements of IEC 61284.
Such tests can be conducted before product release and during routine production to assess conformity with the applicable quality requirements.
