Gigabit Ethernet (2)

• 1000base-LX

  • length 3,000 m; fiber single or multimode; LW Laser 1300nm

• 1000base-SX

  • length 260-550 m; fiber multimode only; SW Laser 830nm

• 1000base-CX

  • length 25 m; short copper jumpers

• 1000base-T

  • length 100 m; Cat 5 UTP

• The Gigabit ethernet standard adopts both the original IEEE 802.3 ethernet specifications and Fiber Channel ANSI X3T11 for physical interface. Gigabit ethernet retains ethernet's link layer protocol, maximum frame size, and frame format. Gigabit includes both full and half-duplex operating modes
