100GBASEstandaarden

100GBASE standards refer to a family of Ethernet physical layer specifications that enable data transmission at a rate of 100 gigabits per second. These standards are defined by the IEEE 802.3 working group and are crucial for high-performance networking in data centers, high-frequency trading, and other bandwidth-intensive applications. The primary goal of 100GbE is to increase network capacity and reduce latency, allowing for faster data transfer and more efficient communication between devices.

Several variations of 100GBASE exist, differing primarily in their physical media and reach. 100GBASE-SR4 uses parallel optical fibers over short distances, typically within a data center. 100GBASE-LR4 and 100GBASE-ER4 employ single-mode optical fibers for longer-reach applications, suitable for inter-building or metro network connections. Additionally, standards like 100GBASE-CR4 specify copper cabling for very short connections, often within a single rack.

These standards are built upon existing Ethernet principles but incorporate more advanced technologies to achieve the higher speeds. Techniques such as multiplexing different wavelengths of light (e.g., in LR4 and ER4) or using multiple parallel lanes of data are employed. The adoption of 100GBASE is a significant step in the evolution of networking, paving the way for even higher speeds in the future.
