What is BS EN 4641-001 - Fibre optic cable about ?
BS EN 4641-001 is a European Standard that specifies general characteristics, conditions for qualification, acceptance and quality assurance, as well as the test methods and groups for fibre optic cables with a cladding of 125 µm outside diameter.
Who is BS EN 4641-001 - Fibre optic cable for ?
BS EN 4641-001 on fibre optic cable is useful for:
- Aerospace avionic and fibre optic technology
- Spacecraft and space products manufacturers
- Aerospace and defence industries
- Design engineers for optical cables
- Quality control personnel for spacecraft products
- Manufacturers of optical cables
Why should you use BS EN 4641-001 - Fibre optic cable ?
Fibre optic cables are cables that contain several thousands of optical fibres in a protective, insulated jacket. The optical fibres are very thin strands of pure glass, which transmit information in the form of light.
The cladding is a special coating that keeps the light from escaping the glass core. 125 refers to the diameter of the outside of the fibre cable's cladding. BS EN 4641-001 provides detailed specifications about the characteristics and performance requirements as well as test methods of fibre optic cables.
With the high level of data security required in military and aerospace applications, fibre optic cables offer the ideal solution for data transmission in these areas. Hence as a manufacturer, you can use BS EN 4641-001 guidelines to improve the production of applications involving fibre optic cable.
By adopting BS EN 4641-001 guidelines, you can manufacture best quality optical cable.
