A BNC cable (Bayonet Neill-Concelman) is a type of coaxial cable commonly used for various video, audio, and data transmissions, including in surveillance systems, broadcast equipment, and networking. When referring to a BNC cable Eco, it typically means a version of the BNC cable designed with environmentally friendly features. This can involve:

1. Recyclable Materials: The cable may be made from materials that are easier to recycle, reducing its environmental impact when disposed of.

2. Reduced Toxicity: Eco-friendly BNC cables may avoid the use of harmful substances such as PVC (polyvinyl chloride) and other toxic chemicals in their insulation or construction.

3. Energy-Efficient Manufacturing: The production of eco-friendly cables may involve less energy consumption or use of renewable energy sources, contributing to lower carbon emissions.
