Cat 6 cables.
They have several improvements, including better insulation and thinner wires, that provide a higher signal-to-noise ratio, and are better suited for environments in which there may be higher electromagnetic interference. Some Cat 6 cables are available in shielded twisted pair (STP) forms or UTP forms. For most applications, Cat 6 cable is adequate for gigabit Ethernet, and it is much less expensive than Cat 7 cable.

Optical fiber cabling.

4B5B NRZI coded signaling, two strands of multi-mode optical fiber. Maximum length is 400 meters for half-duplex connections (to ensure collisions are detected) or 2 kilometers for full-duplex.

Fast and less interference.
