Faced with the challenges posed by the surge in network data traffic in major data hubs, cloud computing, and other markets, the deployment of high-speed data ports has been accelerated. There is an urgent need to upgrade from the existing 100G network architecture to a higher speed network architecture. Relatively speaking, the 800G era is still far away, and 400G is already a better choice for the post 100G era. Whether in terms of product applications, product performance, or economic applicability, the comprehensive advantages of 400G are quite obvious, It is currently a better choice for the interconnection of Leaf and Spine in DCI.

Detrine Technology's 400G QSFP-DD FR4 adopts the mainstream DSP scheme in the industry, with four non cooled EML lasers with CWDM wavelengths. Based on PAM4 modulation, it achieves a single wave rate of 106.25Gbps, and through optical MUX devices, it reaches a single fiber transmission rate of 400G, with a transmission distance of up to 2Km.

At three temperatures, the TDECQ of the transmitter eye diagram is less than 2dB, and the sensitivity of the receiver OMA is less than -8.5dBm@2E-4 .

At present, the 400G series products have been sent to customers in North America, South Korea, and Europe for small-scale sample testing, and the excellent product performance has met their expected needs.

After years of layout in high-speed data communication products, Xinrui Technology has achieved batch shipment of 25G/40G/100G/200G/400G series high-speed data communication products. It can be foreseen that 200G/400G products will be the mainstream trend in the data hub market in the next three years. Xinrui Technology has invested a lot of research and development resources and has successively developed the 200G/400G QSFP-DD series products, 200G/400G QSFP-DD DAC, AOC products, 200G QSFP56 and other categories of products to provide customers with the next generation data hub optical module solution Support for. With the increasing demand for higher speed optical modules in data hubs, Xinrui Technology will leverage its technological and market advantages to promote 400G high-speed optical modules and more high-speed products to customers, providing them with better products and services, and contributing to the development of the next generation of data hubs.
