Advantages of 200G QSFP-DD
The advantage of QSFP-DD is that the 1U panel can achieve a density of 36 * 200G/400G, and is compatible with the QSFP forward and backward, the existing QSFP28 optical modules and AOC/DAC high-speed cables.
The main difference is that the 200G QSFP-DD PSM8 adopts an 8-way 1310nm single-mode optical fiber parallel scheme, and the transmission distance can reach 10km; The 200G QSFP-DD SR8 adopts a multi-mode optical fiber parallel scheme, and the transmission distance on the OM4 optical fiber link can reach 100m.
The SFP-DD small automatic pluggable double density packaged optical module doubles the bandwidth (25G/50G) of the SFP28 or SFP56. It supports a higher rate (50G/100G) while maintaining backward compatibility of the SFP28 or SFP56. The QSFP-DD four channel small pluggable double density packaged optical module, defined by the QSFP-DD MSA group, doubles the density of QSFP28 or QSFP56. It has eight channels, and the rate per channel is up to 25G or 50G. Therefore, it supports 200G or 400G optical transmission.
Another predictable trend in the data center optical interconnection market is to phase out the low-speed optical modules in the core network and data center. The main transformation is from 10G to 40G and higher 100G and 200G. The new development of 100G optical devices paved the way for 200G/400G optical devices. As a professional optical module manufacturer, we are also constantly developing high-speed products. In general, the optical module market is developing towards higher speed, lower power consumption and smaller shape or size.
