Transceiver : NVIDIA/Mellanox Compatible OSFP Optical Transceiver Series (1.6T XDR 2xDR4 / 800G XDR DR4 / 800G NDR 2xDR4 / 800G NDR 2xSR4 / 400G NDR SR4) for Quantum-X800 QM3400, Quantum-2 Switches, and NVIDIA DGX B300/H100 AI Systems
The NVIDIA/Mellanox compatible OSFP optical transceiver series provides ultra-high-speed connectivity tailored for high-performance computing (HPC) and AI data center networks using InfiniBand XDR and NDR protocols. Leading the lineup is the flagship 1.6Tb/s twin-port OSFP 2xDR4 transceiver (MMS4A00-XM compatible), which integrates two independent 800Gb/s DR4 optical engines. Each engine operates with 4 lanes of 200G-PAM4 signaling, utilizing an electrical configuration of 8x212Gb/s PAM4 to deliver low-latency, parallel single-mode fiber (SMF) connectivity over distances up to 500 meters.
Featuring dual MPO-12/APC optical interfaces and high-performance 1310nm EML laser transmitters paired with PIN receivers, this dual-engine 2×800G architecture enables the Quantum-X800 QM3400 72-cage switch to scale up to 144 ports of 800Gb/s InfiniBand connectivity. Enclosed in an Integrated Heat Sink (IHS / Finned Top) shell operating within a power envelope of ≤33.5W and case temperatures from 20°C to +70°C, these modules ensure maximum thermal efficiency across dense AI compute topologies and NVIDIA DGX B300 server connections.
Key Features
- Dual-Engine 1.6Tb/s (2x800G) Architecture: Integrates two independent 800G DR4 optical engines utilizing 8x212Gb/s electrical PAM4 signaling over two MPO-12/APC connectors.
- Quantum-X800 Scale-Out Optimization: Enables Quantum-X800 QM3400 72-cage switches to expand capacity up to 144 ports of 800Gb/s InfiniBand XDR connectivity.
- High-Performance EML Optical Engines: Powered by 1310nm EML lasers and PIN photodetectors for superior signal integrity and transmission reach up to 500m over SMF.
- Optimized Thermal Management (IHS): Built with an Integrated Heat Sink (Finned Top) shell engineered to handle ≤33.5W power consumption in air-cooled high-density switches.
- Broad Multi-Speed Compatibility: Available in 1.6T XDR, 800G XDR/NDR, and 400G NDR speeds for switch-to-switch and switch-to-DGX server links.
