Which is the mainstream for 200G data centers, 200G QSFP56 or 200G QSFP-DD?
With the rapid development of optical communication and Internet, the demand for network has also grown in line with the trend, resulting in the rapid growth of traffic in telecom backbone network at the rate of 50% to 80% per year. To meet user demand, the transmission rate of optical communication has increased its development, from 10G, 25G, 40G before to 100G, 200G, 400G, etc. today. Although 100G optical transceivers have become the mainstream of the market, the bandwidth and port density requirements are still increasing, which further drives the technology to 200G, 400G or higher speed systems. What Are the Package Types of 200g Optical Modules? Currently, there are two main types of 200G optical transceivers: 200G QSFP56 and 200G QSFP-DD. The QSFP56 was introduced in 2017 and by its very nature represents a design advancement from earlier QSFP transceivers, while the QSFP-DD was still in the development stage during the same time frame. Both are designed for high-performance co...
