  inShielded twisted-pair cableCable sheath, and increase the leakage throughout the entire length of the cable wires, is the earth wire, the wire connected to the cable shielding layer.To have the effect of shielding.
  Aluminum foil is commonly used to prevent high frequency interference, such as high voltage, and metal mesh is to prevent the low frequency interference, namely everyday 50 hz frequency interference.
  shieldingNetwork lineHas better anti-interference performance than the shielding network line, higher transmission rate.
  If it is indoor use shielding network line will have a better transmission quality, indoor should choose shielding network on-line?
  The answer is no, in fact, indoor LAN us more is to use the shielding network line.
  Although is shielded twisted-pair cable transmission rate faster, anti-interference performance is stronger, but to connect systems have high requirements, need all shielding device, and require the building ground system.
