Quad Small Form Factor Pluggable Double Density Active Optical Cables
QSFP-DD is a new module and cage/connector system similar to current QSFP, but with an additional row of contacts providing for an eight lane electrical interface. The data rate of each channel can reach 25Gb/s through NRZ modulation technology, realizing 200G network transmission. Also, the data rate of each channel can reach 50Gb/s by the PAM4 modulation technology, achieving 400G network transmission, which is suitable for high-performance computing data center and cloud network. These cables utilize fiber wiring and are an ideal low-cost option for short reach applications. We also offer these cables in QSFP, QSFP56, QSFP+ and SFP+ formats.
