CATEGORY-3(802.3 10BaseT Ethernet)

?? Introduced in the early 1990s, Category 3 cabling has four wires and was the first cable to support 10BaseT Ethernet as well as digital communications. It is still available in older homes, but the 10 Mbps data rate is considered too slow for today's networks. There are a few new products that come with 10BASE-T only. Most hubs, switches, and Ethernet adapters on the market are 10BASE-T / 100BASE-TX / 1000BASE-T devices. This means it supports data transfer rates of 10, 100 and 1000 Mbps respectively. There is also 10GBASE-T, which supports data transfer of 10 gigabits (billions of bits) per second.

In addition to 10BASE-T, 10 Mb Ethernet can also be used by the following media types:

10BASE-2: Thin coaxial cable with a maximum length of 185 m.

10BASE-5: Thick metal coaxial cable with a maximum section length of 500 m.

10BASE-F: Fiber Optic 10BASE-36. Broadband coaxial cable carries multiple base frequency channels for lengths of up to 3,600 m. Of these, F represents optical cable; 2, 5 and 36 indicate the length of the coaxial cable section; The first represents 185 m. For 200 the length is equal to 2.

??How does 10BASE-T work?

10BASE-T networks are usually connected to a central hub in a star topology. Cables used for unshielded twisted pair cabling are Category 3, Category 4 or Category 5. The cables are sealed with RJ45 connectors. Patch panels prepare electrical wiring and create termination points for electrical cables in the wall, and patch cables connect each port of the panel to the root hub. For easy access, cables are hidden in electrical equipment or in the installation of racks.

since the maximum length of cables in a 10BASE-T network is 100 m, repeaters must be made longer. Two or more communication lines (minimum length is 2.5 m) are connected using repeaters. Cascaded regular hubs or stackable hubs are used to connect multiple computers together. But it only supports up to 1,024 nodes. In this case, a maximum of 200 or 300 nodes can avoid conflict and achieve good performance.
