APPLICATION
Cat6 Cable is a cable standard for Gigabit Ethernet and other network protocol, suitable for 10BaseT,
100BaseTx & 1000BaseT (Gigabit Ethernet) application. In addition, these cables are with copper
wire braid armoured & flame retardant mud resistant outer sheath, providing additional mechanically
protection still maintaining the flexibility of the cable.

STANDARDS
Basic design to EIA/TIA 485
