Product description

This NVIDIA/Mellanox MMS4X50-NM-compatible OSFP transceiver is an 800Gbps twin-port OSFP 2×FR4 single-mode module with an integrated heat sink (IHS, closed-top), dual LC connectors and 100G-PAM4 modulation, supporting link lengths of up to 2 km over single-mode fiber.

The module meets InfiniBand NDR end-to-end system certification and supports deployment on 2×400G InfiniBand switches. Paired with a 1:2 breakout cable, it enables a 2×400G breakout mode by activating two optical channels on each branch path, delivering lower power consumption and flexible breakout connectivity. With high-bandwidth transmission and ultra-low BER, it is optimized for supercomputing, AI and HPC environments and is seamlessly compatible with H100/H200 platforms.

Product highlights

  • Integrated low-power DSP for stable performance at scale
  • Optimized power budget, max power consumption 16.5W
  • Compliant with OSFP MSA 5.0 and IEEE802.3ck and IEEE 802.3df standards
  • Supports breakout to lower-rate links for flexible fabric design
  • Tested on live switch / NIC platforms to ensure performance, quality and reliability

Applications

  • AI data center & GPU cluster interconnect
  • Spine-leaf switching fabric
  • Data center interconnect (DCI) and campus links
  • Hyperscale, cloud and high-performance computing networks
