NVIDIA Compatible 1.6T 2xFR4/FR8 OSFP224 PAM4 1310nm 2km IHS/Finned Top Dual Duplex LC SMF Optical Transceiver Module
High-Density 1.6T Connectivity for Next-Generation AI & HPC Fabrics
Engineered for the demanding throughput of NVIDIA Quantum™-X800 and Spectrum-X platforms, this 1.6T OSFP224 optical transceiver delivers industry-leading bandwidth and signal integrity for large-scale AI clusters and data centers. Utilizing advanced PAM4 modulation (8x 200G PAM4 electrical to dual 4x 200G PAM4 optical), the module supports a total aggregate data rate of 1600 Gb/s over Single Mode Fiber (SMF).
Featuring a 1310nm CWDM4/LAN-WDM wavelength grid and a robust IHS (Integrated Heat Spreader) / Finned Top design, this module is optimized for both air-cooled and liquid-cooled switch environments, ensuring superior thermal management at <26W max power dissipation. With a reach of up to 2km via Dual Duplex LC connectors, it provides flexible deployment options for intra-campus and data center interconnects (DCI).
Key Features:
Ultra-High Bandwidth: 1.6T (2x 800G) twin-port configuration via OSFP224 form factor.
Advanced Modulation: 200G PAM4 per lane electrical and optical signaling.
Extended Reach: 2km transmission over SMF at 1310nm (2x FR4/FR8 compliant).
Thermal Optimization: Finned Top (IHS) design for enhanced heat dissipation in high-density racks.
Interoperability: Fully NVIDIA compatible (MMS4A50-XM equivalent), supporting InfiniBand XDR and 1.6T Ethernet.
Standards Compliance: Compliant with OSFP MSA, IEEE 802.3dj, CMIS Rev 5.x, and RoHS.
Target Applications:
1.AI/ML Training Clusters (NVIDIA DGX, Quantum-X800).
2.High-Performance Computing (HPC) Interconnects.
3.1.6T to 2x 800G Breakout Connectivity.
4.Enterprise Core and Spine-Leaf Architectures.
Empower your network with the scalability and reliability required for the next era of accelerated computing.
