QSFP-DD vs QSFP28 / QSFP56 how we got here with so many different QSFP’s ? The rapid growth of cloud data center networking and interconnections are pushing the technology development to meet the ever higher bandwidth connectivity demands. From the rise of 40G-QSFP transceivers and ever successful advancement to the 100G-QSFP28 form-factor, the next major step is prevalence of 200G and 400G Ethernet technology with QSFP-DD form-factor optical transceivers.
Current widespread use of 100G QSFP28 technology transceiver form-factor, followed by 200G QSFP56 transceiver form-factor, have led to a completely new optical transceiver form-factor QSFP-DD.
Confused? The following sheet will help to quickly understand the main differences between QSFP-DD, QSFP56 and QSFP28.
