The connectors feature a "bubble" which protects the locking clip on the RJ45 from damage or being snapped off during transport or installation. The flush mounded design allows the patch cables to be installed side by side in high-density network switches. The strain relief allows the cables to move without damaging the cable or breaking away from the connector while it is plugged in a device.Low Smoke Zero Halogen cable reduces the amount of toxic and corrosive gas emitted during a fire. 10 times faster than Gigabit Ethernet, 10GE supports a data rate of 10 Gbps (billion bits per second). Screened and Foil (Shielded) Twisted Pair. Each individual pair is screened by foil and features an overall outer sheath. This shielding protects the cable from EMI (Electro-Magnetic Interference).
