QSFP-DD (400G) Standard

Precision is constantly updating our offerings with the latest technology and remains a cost effective supplier for network providers looking to upgrade to the latest 400G transceivers. We have a variety of 400G optical transceiver modules with varying specifications, including QSFP-DD DR4, QSFP-DDDR4+, QSFP-DD FR4 and QSFP-DD SR8.

Each quad small form-factor pluggable double density module features QSFP interconnects through an eight lane electrical interface. Each of the eight lanes runs at 50Gb/s speeds so your applications can reach 400G speeds. The “DD” stands for double density, meaning the ASIC ports are doubled and the mechanical interface of the QSFP-DD is slightly deeper than four lane models to accommodate the extra row of lanes.
