What are the Gigabit Ethernet specifications and the governing IEEE standards?
What will be an ideal response?
The Gigabit Ethernet specifications and the governing IEEE standards are:
• 1000Base-TX (802.3ab)-Uses four pairs of Category 5 unshielded twisted-pair cable. The maximum segment length is 100 meters.
• 1000Base-SX (802.3z)-Uses multimode fiber. The maximum segment length varies based on what type of fiber is being used. For example, using a 62.5 micron core, the maximum length is 220 meters. When using a 50 micron core, the maximum length is 550 meters.
• 1000Base-LX (802.3z)-Uses single-mode fiber. The maximum distance for this standard is 10 kilometers.
• 1000Base-CX (802.3z)-Uses shielded twisted-pair copper cabling. The maximum segment length is 25 meters.
