GIGALIGHT Redefines 200G Data Centers With Introducing New PAM4 DML-based 200G QSFP56 DR4/FR4 Optical Module
Shenzhen, China, June 2023 — In terms of cost-effectiveness and long-term viability, 200G data centers continue to reign supreme. The advantages of low power consumption and effective technical solutions make them particularly appealing for underdeveloped countries or enterprise-level data centers. As the open optical network devices explorer, GIGALIGHT is dedicated to the development of cost-friendly data center technologies. In line with this vision, GIGALIGHT recently unveiled a 200G QSFP56 DR4/FR4 data center optical module based on the PAM4 DML platform, further solidifying and highlighting the advantages of 200G in certain data center domains.
The new 200G QSFP56 DR4/FR4 module utilizes PAM4 modulation technology and DML lasers to deliver high-speed transmission and exceptional performance. Two versions are available, allowing for selection based on the mid-short distance transmission within the data center. Both the DR4 and FR4 modules have a power consumption of less than 6W, resulting in reduced energy consumption and operational costs. The FR4 module exhibits superior receive sensitivity OMA compared to the DR4 module (by 1dBm), with excellent performance parameters including high OMA sensitivity (<-9dBm). This makes it adaptable to various application scenarios, providing high-quality signal transmission and maintaining a good eye diagram quality under PAM4 modulation.
With the continuous growth of network data and the diversification of application demands, data centers indeed require higher bandwidth and greater scalability. Under the premise of meeting broadband requirements and application needs, the 200G data center demonstrates clear advantages compared to both the 100G and 400G data centers. It is crucial to have an objective understanding of the true meaning of “advantages” and not simply chase after the evaluation based solely on “technological advancements.”
For a comprehensive return on investment in a 400G data center, the only viable path is to adopt a silicon photonics technology platform. As for the emerging star, the 800G data center, it also requires a clear definition of its application scope. It is crucial to understand that 800G represents a diversified data center.
