Early Ethernet

Megabit Ethernet

Xerox Ethernet (also known as "Xerox Ethernet") is the prototype of Ethernet. The original 2.94Mbit/s Ethernet was used only internally at Xerox. In 1982, Xerox formed the DIX Alliance with DEC and Intel, and jointly published the specification of Ethernet Version 2 (EV2), which was put into the market and widely used. The EV2 network is 10BASE5 recognized by IEEE.

10BROAD36 -- is out of date. An early standard to support long distance Ethernet. It is used on coaxial cables, in a wideband modulation technology similar to cable modem systems.

1BASE5 - also known as star LAN, the rate is 1Mbit/s. It was a commercial failure, but it was also the first use of twisted pair.

10Mbps Ethernet

10BASE5 (also known as Thick Ethernet or yellow cable) - the earliest implementation of 10 Mbit/s Ethernet. Earlier IEEE standards used a single RG-11 coaxial cable, with a maximum distance of 500 meters and the ability to connect transceivers for up to 100 computers, with 50 ohm terminal resistors at both ends of the cable. The receiving end inserts the inner core and shield of the cable through a so-called "plug-in tap". Use an N-type connector at the end of the cable. Although there are still a few systems in use today due to extensive early deployment, this standard has actually been replaced by 10BASE2.

10BASE2 (also known as Thin Ethernet or analog network) - 10BASE5 products, using RG-58 coaxial cable, the longest transfer distance of about 200 meters (actually 185 meters), can only connect 30 calculators, calculators use T-adapter to connect to the network card with BNC connector, And you need 50 ohm terminators at both ends of the line. Although it is not as good as 10BASE5 in terms of capability and specifications, it is more widely used and eliminated 10BASE5 because of its thinner wire, convenient wiring and cheap cost. Due to the popularity of twisted pair, it has also been replaced by various twisted pair networks.

StarLAN - The first 10 Mbit/s Ethernet standard implemented on twisted pair. Later developed into 10BASE-T.

10BASE-T - Using 4 strands (two pairs of twisted pair) of Category 3 twisted pair, Category 4 twisted pair, and Category 5 twisted pair, 100 meters. An Ethernet hub or Ethernet switch is located in the middle to connect all nodes.

FOIRL - Fiber Optic repeater Link. Fiber Ethernet original version.

10BASE-F - 10Mbps Ethernet fiber standard general name, 2 km. Only 10BASE-FL is widely used.

10BASE-FL - An upgrade of the FOIRL standard.

10BASE-FB - Backbone technology used to connect multiple hubs or switches, deprecated.

10BASE-FP -- Passive star network without relay, no practical application case.
