The 10Base-T UTP Ethernet and 10Base-2 Coax Ethernet were very popular in the early to mid 1990's when 100 Mbps
network cards and hubs/switches were very expensive. Today's prices have dropped so much that most vendors don't focus on the 10Base networks but the 100Base ones and, at the same time, support the 10 BaseT and 10Base-2 standard. We will also talk about10Base5/F and 35.
So what does 10 BaseT/2/5/F/35 mean?
We are going to break the "10 Base T" into three parts so we can make it easier to understand:
T/2/5/F/35UTP -Unshielded Twisted Pair
Most networks use UTP cable and RJ-45 connectors or Coaxial cable with BNC "T" connectors, for this reason special devices made their way to the market that allow you to connect an AUI network card to these different cable networks.
The picture below shows you a few of these devices:
- 10Base-T works for 10 Mbps networks only and uses unshielded twisted pair cable with RJ-45 connectors at each end and maximum length of 100 meters. They also only use two pairs of cables.
- 10Base-2 works for 10 Mbps networks only and uses coaxial cable. Maximum length is 185 meters and BNC "T" connectors are used to connect to the computers; there are special terminators at each of the coaxial cable.
- 10Base-5 works for 10 Mbps networks only and uses thick coaxial cable. Maximum length is 500 meters and special "AUI" connectors (DB-15) are used to interface with the network card.
- 10Base-F works for 10 Mbps networks only and uses fiber optic cable.
