MMA2P00-AS Mellanox Transceiver

High-Density 25GbE SFP28 SR Optical Transceiver for Short-Reach Data Center Links with the MMA2P00-AS

The MMA2P00-AS is a Mellanox/NVIDIA SFP28 SR 25GbE optical transceiver engineered for predictable, low-latency short-reach connectivity in Top-of-Rack and within-row architectures. By converting 25GbE electrical lanes to 850nm multimode fiber optics, the MMA2P00-AS supports consistent signal integrity across high-port-count switching and server NIC deployments where copper reach, bundle size, or EMI constraints limit operational efficiency.

Built around an 850nm VCSEL optical engine and LC duplex connectivity, the MMA2P00-AS is optimized for MMF patching up to 100m, aligning with rack-to-rack and leaf-spine interconnect patterns common in enterprise data centers and HPC pods. The SFP28 form factor enables dense PCIe-attached NIC and switch line-card designs without forcing changes to host CPU platforms, while EEPROM monitoring per SFF-8472 simplifies fleet operations through standard telemetry and inventory control.

Why Choose the MMA2P00-AS?

The MMA2P00-AS delivers a pragmatic density-to-performance profile for 25GbE fabrics, enabling scale-out designs with repeatable optical behavior and minimal cabling overhead. In environments where rapid expansion and consistent port utilization are priorities, the MMA2P00-AS supports reliable deployment logic across switch-to-switch and host-to-switch links, helping standardize optics selection and reduce operational variance.

Mellanox engineering emphasizes interoperability and data center readiness, aligning the module with MSA requirements such as SFF-8402 and SFF-8472, and ensuring RoHS compliance for enterprise procurement. This approach targets stable link establishment, predictable diagnostics, and long-term maintainability across mixed infrastructure generations.

Key Applications:

• 25GbE Top-of-Rack to leaf-spine interconnects
• HPC/AI cluster host-to-switch short-reach optics
• Within-row and within-rack MMF patching
• High-density 25GbE NIC uplinks
