Product description

This NVIDIA/Mellanox InfiniBand MMS4X00-NM-compatible OSFP transceiver is a twin-port 800Gbps IHS/finned-top DR8 single-mode module with dual MPO-12/APC connectors and 100G-PAM4 modulation, supporting link lengths of up to 500 m over single-mode fiber.

The module meets InfiniBand NDR end-to-end system certification. 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
  • 800G to breakout links in high-density fabrics
  • Hyperscale, cloud and high-performance computing networks

Supply & compliance FAQ

How do the proposed FCC rules on optical transceivers affect availability?

The FCC rulemaking reported in August 2026 is still a draft. As reported, it would apply to new model authorizations, while models already deployed and shipping would continue to be supplied. Current PhoScale shipments are unaffected, and we hold inventory in our US warehouse. We track the rulemaking closely and publish updates on our Insights page.

Can you provide compliance documentation for your transceivers?

Yes. Every SKU ships with per-unit test reports, and compliance documentation (FCC, FDA laser, RoHS) is available on request as part of our ongoing compliance program.

How do you protect buyers against supply-chain disruption?

Three ways: US-warehouse stock for immediate needs, multi-source manufacturing across tier-one Asian production partners, and allocation planning for project and annual-supply customers. See our Supply Assurance page for details.

What lead times should we plan for on 800G and 1.6T optics?

In-stock models ship from our US warehouse immediately. For volume orders, typical lead times are 2–6 weeks depending on model and quantity — submit an RFQ for a confirmed date against current allocation.
