Ethernet at The Physical Layer - 0 views

anonymous on 11 May 13Digital, Intel and Xerox (DIX) group firstly deployed the Ethernet. DIX group very first created and deployed the first Ethernet LAN Specification which the IEEE used to create the IEEE 802.3 committee. It was 10Mbps network which ran on coax, then ultimately on twisted pair and fiber media. Later, the IEEE expanded the 802.3 Committee into two new committees recognized as 802.3u (Fast Ethernet) and 802.3ab (Gigabit Ethernet on category 5) and then eventually 802.3ae (10Gbps over fiber and coax). Whenever you've to design a Local Area Network (LAN), you must have to be aware of the multiple kinds of Ethernet media available to you. Well, I suggest you to use Gigabit Ethernet to each desktop and 10Gbps between switches. Because, if you combine and match up the multiple kinds of Ethernet media techniques presently obtainable, you can arise with a cost effective network solution which works great. The following table describes the IEEE 802.3 and original Ethernet Physical layer specifications.
