The NVIDIA/Mellanox Compatible Cable is an 800Gb/s twin-port OSFP to 2x 400Gb/s twin-port OSFP passive Direct Attached Copper dual breakout cable for 400Gb/s End-to-End Infiniband solutions. It is compliant with OSFP MSA (Multi-Source Agreement) and IEEE 802.3ck standards. Each end includes an EEPROM which provides product identification and characteristics to the host system.
The 8-channel twin-port OSFP end uses a finned top form-factor for use in Quantum-2 switch cages, while the two 400G ends support 4-channels of 100G-PAM4 (400G) and use a flat top OSFP for use in ConnectX-7 adapters using riding heat sinks on the connector cage. The main use of the cable is linking an 800G switch to OSFP-based 400G network adapter cards.
Featured with low latency, low power consumption and cost-effective performance, this cable enables 800G to dual 400G breakout connections for server-to-TOR links in AI/ML training clusters, hyperscale cloud data centers, and high-performance computing environments.

Different Connector Shells Match Different Devices
The 800G OSFP end uses a finned top form-factor for use in switches, while the two 400G ends support 4-channels of 100G-PAM4 (400G) and use a flat top OSFP for use in ConnectX-7 adapters, enabling 800G to dual 400G connectivity.
Professional Testing Environment
Scenario Application Testing
FS Testing Center has most of the mainstream brand switches and devices. Before shipment, we will test them on the corresponding switches to ensure the transceivers are 100% compatible with your system.
Performance Testing
FS stringently selects a series of items in a professional testing environment to ensure the perfect blend of product performance and reliability.
Low BER on par with NVIDIA Originals
During LL-FEC (272,257) testing, FS DACs achieve a Pre-FEC BER of 1E-8 to 1E-10 with near-zero post-correction errors, ensuring link stability and reducing operations & maintenance (O&M) complexity in InfiniBand networks.
