What is 100BASE-FX? Explanation of basic concepts of Ethernet technology using optical fiber
Introduction
Ethernet is a widely used networking technology that allows devices to communicate with each other within a local area network (LAN). It has evolved over the years, offering faster speeds and improved performance. One such variation is 100BASE-FX, which utilizes optical fiber to transmit data. In this blog post, we will explore the basic concepts of Ethernet technology and delve into the details of 100BASE-FX.
Understanding Ethernet
Ethernet is a set of standards that define how data is transmitted and received over a network. It operates using packets of data called frames. Each frame contains the source and destination MAC addresses, as well as the data payload.
What is 100BASE-FX?
100BASE-FX is an Ethernet standard that operates at a data rate of 100 Mbps. The “100” in its name refers to the transmission speed in Mbps, while “BASE” indicates that it is a baseband technology (meaning it uses the entire bandwidth of the medium for transmission). The “FX” stands for “fiber optic”, signifying that it utilizes optical fiber for data transmission.
Features of 100BASE-FX
One of the key advantages of 100BASE-FX is its ability to transmit data over longer distances compared to traditional copper-based Ethernet. Optical fiber is capable of carrying data over several kilometers without signal degradation. This makes 100BASE-FX an ideal choice for network segments that require long-distance connectivity.
Additionally, 100BASE-FX offers improved immunity to electromagnetic interference, making it suitable for deployment in environments with high levels of electromagnetic noise, such as industrial settings.
How does 100BASE-FX work?
100BASE-FX operates in full-duplex mode, allowing for simultaneous transmission and reception of data. The data is carried over two strands of optical fiber, one for transmit (TX) and the other for receive (RX). These fibers use LED or laser light sources to convert electrical signals into optical signals and vice versa.
The data transmission occurs in the form of light pulses, with each pulse representing a 0 or a 1. These pulses of light travel through the optical fiber, reaching the destination device where they are converted back into electrical signals. This process enables reliable and high-speed data transfer over the network.
Conclusion
100BASE-FX is a variant of Ethernet technology that utilizes optical fiber for data transmission. It offers faster speeds, longer distances, and improved resistance to electromagnetic interference compared to traditional copper-based Ethernet. By understanding the basic concepts of Ethernet and the features of 100BASE-FX, network administrators can make informed decisions about implementing this technology in their networks.
