200GbE
200GbE, or 200 Gigabit Ethernet, is a high-speed Ethernet standard designed to support data transmission rates of 200 gigabits per second (Gbps). It is part of the IEEE 802.3 Ethernet family and was standardized in 2019. The primary goal of 200GbE is to provide a scalable and efficient solution for data centers and high-performance computing environments, addressing the increasing demand for bandwidth.
200GbE operates over a single lane of 100GBASE-LR4, which uses four wavelengths of light to achieve the
The adoption of 200GbE is driven by the need for higher bandwidth in data centers to support
200GbE is backward compatible with 100GbE, allowing for a smooth transition from older to newer technologies.
