What is 100BASE-T4? Easy-to-understand explanation of the basic concepts and characteristics of Ethernet communication
Ethernet communication is a fundamental technology used for networking computers and devices in a local area network (LAN). One of the popular Ethernet standards is 100BASE-T4. In this blog post, we will delve into the basic concepts and characteristics of 100BASE-T4 Ethernet communication in an easy-to-understand manner.
Understanding Ethernet Communication
Ethernet is a protocol that allows devices to communicate over a common network medium. It enables the transmission of data by modulating digital signals into electrical impulses sent over copper wires or light pulses through optical fibers. Ethernet networks utilize various standards, depending on the data transmission speed and other requirements.
Introducing 100BASE-T4
100BASE-T4 is an Ethernet standard that supports a data transmission rate of 100 megabits per second (Mbps). The “100” in its name refers to the speed in megabits per second, while “BASE” represents the baseband transmission over twisted-pair copper cables. The “T4” indicates that it uses four twisted pairs of copper wires.
Characteristics of 100BASE-T4
1. **Data Transmission**: 100BASE-T4 allows the simultaneous bi-directional communication of data, with a maximum transmission speed of 100 Mbps. This speed is suitable for tasks such as file transfers, video streaming, and online gaming, providing a balance between performance and affordability.
2. **Medium**: 100BASE-T4 uses four pairs of Category 3 or higher twisted-pair copper cables to transmit data. These cables are readily available and easy to install, making 100BASE-T4 Ethernet communication accessible for most network setups.
3. **Distance Limitations**: The maximum cable length in 100BASE-T4 networks is 100 meters (328 feet). Beyond this distance, signal degradation can occur, leading to errors in data transmission. To cover larger areas, network switches or repeaters can be utilized to extend the reach of the network.
4. **Compatibility**: While 100BASE-T4 is an older Ethernet standard, it is still compatible with modern devices. Many network interface cards (NICs) and switches support multiple Ethernet standards, allowing seamless integration with existing infrastructure.
In Conclusion
100BASE-T4 is an Ethernet standard offering a data transmission rate of 100 Mbps, making it suitable for various network tasks. It utilizes four twisted pairs of copper cables, and despite being an older standard, it remains compatible with modern devices. Understanding the basic concepts and characteristics of Ethernet communication, such as 100BASE-T4, enables us to make informed decisions when setting up and expanding networks.
