Top Nvidia® Compatible Transceivers
Matching the right transceiver to your Nvidia®/Mellanox infrastructure is critical for both performance and scalability. Below are some of our most widely adopted solutions for modern AI and HPC networks.
800G Solutions
| Product | Speed | Reach | Connector | Application |
|---|---|---|---|---|
| OSFP 2xFR4 | 800G | 2km | 2x LC Duplex | Twin-port, mid-reach cluster fabrics |
| OSFP 2xDR4 | 800G | 500m | 2x MPO-12/APC | Twin-port connections for GPU/AI clusters |
| OSFP 2xSR4 | 800G | 50m | 2x MPO-12/APC | High-speed, in-rack links |
Note: Twin-port transceivers combine two 400G connections into one 800G form factor, maximizing port density.
