What's wrong with low-quality network cables?

JunChen LED tell you how to find best network cable,come to read this article!

1. Conductor material

Copper-coated iron, copper-coated aluminum, mixed copper (compared to standard Cat 6 and Cat 5e which use oxygen-free pure copper).

2. Diameter

0.35mm to 0.48mm (Cat 6 is 0.565mm; Cat 5e is 0.51mm).

3. Outer sheath material

Recycled scrap (vs. eco-friendly PE + flame-retardant PVC).

4. Total length per box

150 to 280 meters (vs. 305 meters).

5. The flexibility of the network cable

Some manufacturers add other metal elements to copper when producing network cables to reduce costs. The resulting wires are harder, less flexible, and have a dent-like feel. They do not easily return to their original shape after bending and are prone to breaking during use.（vs.Copper wire made from pure copper should feel soft and full to the touch, allowing it to be bent freely and gradually return to its original shape after bending.）

6.The flammability of network cables

Authentic network cables should only emit white smoke and gradually melt and deform over time, while counterfeit cables can be easily ignited within less than 2 seconds, producing a large amount of black smoke.

7. Price

low-quality network cables price is also very cheap, ranging from 50 to 300 yuan.
