QSFP-DD

Quad Small Form Factor Pluggable Double Density

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 modules utilize MTP and LC connectors and are compliant with RoHS, IEEE, and QSFP-DD MSA standards.

Optical Transceiver Standards & Compliance

Never Sourced. Never Recycled.

All components in GigaTech Product optics are manufactured under the same roof and represent the gold standard for reliability and consistency in performance. This vertical manufacture chain allows GigaTech to avoid unnecessary variances in transceiver casing or laser quality often found with online resellers who source their components from an ever changing vendor list. The transceiver is guaranteed to be built from A-Stock never used components overseen by GigaTech Products,

Rigorous Testing & Standards Compliance

The quality and standards of our hardware is one the base foundations of GigaTech Products. All of our components comply with MSA (Multi-Source Agreement) output standards and, in many cases, excel beyond those certification standards. Every transceiver we produce is tested on active network devices to ensure they comply with OEM equipment and are verified to be plug-and-play and do not require work arounds.
