NVIDIA/Mellanox MMA4Z00-NS-FLT (980-9I51A-00NS00) Compatible 800G 2xVR4 OSFP Flat-Top Transceiver for ConnectX-8 C8180 SuperNIC

The NVIDIA/Mellanox MMA4Z00-NS-FLT compatible 800G 2xVR4 OSFP optical transceiver is designed for high-bandwidth, short-reach multimode connectivity in NVIDIA ConnectX-8 C8180 SuperNIC deployments. Built on a twin-port OSFP architecture, it provides two independent 400Gb/s VR4 optical channels for an aggregate data rate of 800Gb/s.

The module uses eight 100G-PAM4 optical lanes operating at 850nm and features two MPO-12/APC connectors, with each connector serving one 400Gb/s optical channel. It supports transmission distances of up to 50 meters over compatible multimode fiber, making it suitable for high-density connections within AI infrastructure, high-performance computing environments, and data center networks.

Featuring Broadcom DSP and Broadcom VCSEL technology, this transceiver is designed to support high-speed optical links in demanding 800G network deployments. Its DOM/DDM monitoring capability helps network operators monitor key module operating parameters and support link diagnostics.

The RHS/Flat-Top housing is intended for host platforms designed around this mechanical and thermal configuration, including compatible ConnectX-8 C8180 SuperNIC systems. Proper host compatibility, heatsink integration, and airflow must be verified before deployment. When integrated into a supported ConnectX-8 networking platform, the module can be used as part of a compatible quad-plane architecture, subject to the system’s network design, cabling, and configuration.

For deployments requiring different thermal configurations, confirm whether the host platform supports a Flat-Top or Finned-Top OSFP module before selecting the appropriate version.

Highlights

Optimized for AI and High-Performance Computing Networks

Designed for high-throughput interconnects in AI clusters, GPU computing environments, and data center fabrics. Its dual-channel architecture supports flexible 800G connectivity and can be incorporated into compatible 2x400G network configurations where supported by the host system.

Flexible Integration with ConnectX-8 Platforms

The RHS/Flat-Top housing is intended for compatible ConnectX-8 C8180 SuperNIC systems with the appropriate mechanical and thermal design. This helps system integrators select an optical module that fits the host platform’s cage and cooling arrangement.

Suitable for High-Density Network Architectures

The module is suited to short-reach connections in high-density server and accelerator networks, including links between compute nodes and network infrastructure. In a properly designed and configured system, it can form part of a quad-plane networking deployment to support scalable connectivity.

Optical Monitoring for Network Operations

DOM/DDM monitoring provides access to supported optical and module operating parameters. This information can assist network administrators with link health checks, troubleshooting, and ongoing maintenance in large-scale deployments.

Deployment Requires Host-Level Thermal and Link Verification

Before installation, verify OSFP housing compatibility, host heatsink arrangement, airflow, fiber type, MPO polarity, and lane mapping. These checks help ensure the optical module is correctly integrated into the intended network platform.

Questions & Answers

OSFP-800G-2VR4F: Frequently Asked Questions

Q: What is the difference between Flat-Top and Finned-Top 800G 2xVR4 OSFP optical modules?

A: The primary difference is the module’s top-side thermal design and the host platform it is intended to fit. The Flat-Top version is designed for systems such as the NVIDIA ConnectX-8 C8180 SuperNIC, where cooling is provided by the host’s dedicated heatsink or thermal structure. The Finned-Top version incorporates heatsink fins on the module housing and is intended for platforms designed to accommodate this OSFP cooling configuration, such as certain air-cooled switches. Always verify the module housing, cage design, heatsink clearance, and system airflow requirements before installation. The two versions should not be treated as mechanically interchangeable unless the host platform supports both.

Q: Are the specifications of the OSFP-800G-2xVR4F and OSFP-800G-2xVR4 identical? Can they be interconnected?

A: When both versions have matching optical specifications, including wavelength, transmission distance, modulation, fiber type, and connector configuration, they can be used on the same optical link. Their primary difference is the OSFP housing and thermal design rather than the optical transmission format. For this dual-channel 2xVR4 design, use two compatible multimode MPO-12/APC fiber jumpers, such as the M4MPOA12FB assembly where its specifications match the link requirements. Ensure that connector polarity, fiber mapping, and host configuration are correct. Also confirm that each module’s housing is supported by its respective host platform.
