Gigabit Ethernet
Gigabit Ethernet :
Gigabit Ethernet is defined by three standards generated by IEEE 802.3 working groups. (1) 1000Base-T supports Gigabit Ethernet over 100 meters of Category 5e balanced copper cabling. (2) 1000BASE-SX supports the use of short wavelength Vertical Cavity Side-Emitting Lasers (VCSELs) to transmit data over fiber optic cable. The lasers specified by the Standard operate over Multimode Fiber in the wavelength range of 770 to 860 nanometers. (3) 1000BASE-LX supports the use of long wavelength lasers to transmit data over fiber optic cable. The lasers specified by the Standard operate over either Multimode or Singlemode Fiber in the wavelength range of 1270 to 1355 nanometers
