I used to think that the metal net is shielded, then feel inside the metal foil is shielded. Only if no metal foil can play a role in shielding cable? No shielding will pulse loss during transmission of the pulse?
Shielded cable may lose data, but with a shield, it does not mean that the data will not be lostInterference and shielding are relative
No shielded cable in the transmission will not necessarily produce a signal loss, depending on the surrounding environment is not a lot of interference, if there is interference
Metal mesh and metal foil can be shielded, and some of the cables are still metal mesh, but also shielding network
