What is Thinnet Ethernet?
Thinnet Ethernet, also known as 10BASE2, is an Ethernet standard that was widely used in the 1980s and 1990s for local area networks (LANs). It is called “Thinnet” due to the physical cable it utilizes, which is thinner compared to other Ethernet standards. The cable used in Thinnet Ethernet is a coaxial cable known as RG-58.
The Thinnet Ethernet standard supports a maximum data transfer rate of 10 megabits per second (Mbps) and has a maximum cable length of approximately 185 meters. The cable is terminated using BNC (Bayonet Neill–Concelman) connectors, which provide a secure and reliable connection between network devices. Thinnet Ethernet uses a bus topology, where all devices are connected to a single cable in a daisy chain fashion.
In a Thinnet Ethernet network, each network device is connected to the main coaxial cable using a T-connector. The network devices communicate with each other by sending data packets onto the cable, which are then received and processed by the intended recipient. However, since the network operates on a shared medium, collisions can occur if multiple devices attempt to transmit data simultaneously. To mitigate collisions, Thinnet Ethernet employs a carrier-sense multiple access with collision detection (CSMA/CD) mechanism.
One of the key advantages of Thinnet Ethernet is its cost-effectiveness. The use of the thin coaxial cable made installation and maintenance relatively easy and affordable, especially in small to medium-sized networks. Additionally, the bus topology made it straightforward to add or remove network devices without disrupting the network as a whole.
However, Thinnet Ethernet also has its limitations. The maximum cable length of 185 meters restricted its use to smaller network deployments. Additionally, the shared-medium nature of Thinnet Ethernet meant that network performance could be affected by high network traffic and collisions. As Ethernet technology advanced, faster and more efficient Ethernet standards were developed, surpassing the capabilities of Thinnet Ethernet.
Despite its limitations, Thinnet Ethernet played an important role in the evolution of Ethernet technology. It offered an affordable solution for implementing local area networks and paved the way for advancements in networking. While Thinnet Ethernet is less common nowadays, it still holds historical significance and provides valuable insights into the early stages of Ethernet technology.
What is the Ethernet Standard Below Referred to as Thinnet?
The Ethernet standard below referred to as Thinnet is known as 10BASE2.

To enable communication within the network, Thinnet Ethernet utilized a collision detection mechanism called carrier-sense multiple access with collision detection (CSMA/CD). Each device on the network listened for any ongoing transmissions and waited for an idle channel before transmitting data. If collisions occurred, all devices involved detected the collision and waited for a random period before attempting to retransmit their data.
Thinnet Ethernet’s maximum cable length of approximately 185 meters imposed a limitation on the size of the network. However, it provided a cost-effective solution for smaller local area networks, such as those found in homes, small offices, and educational institutions.
