10/100BASE-T SFPNVIDIA/Mellanox MMS4X00-NS Compatible 800G Twin-port OSFP IHS/Finned Top Transceiver Module
Built for hosts recognizing MMS4X00-NS, this HT-manufactured Twin-port OSFP IHS/Finned Top module delivers 800G transmission at 1310nm. Its rated reach is 100m, with Dual MTP/MPO-12 APC as the physical interface. The specifications and engineering guidance below support structured fiber installations preserve a documented and serviceable optical channel, while keeping HT manufacture separate from the OEM cross-reference.

Applications and Optical Link Design
Use this module for equipment interconnection over the specified single-mode fiber plant, including enterprise backbone, campus, metro or data-center interconnect links according to its rated distance. Confirm that both ends use the same optical standard and wavelength plan, and allow for connector, splice and patch-panel loss within the stated power budget.
Before deployment, check the host port type, supported data rate and firmware requirements. The 800G interface configuration must match the remote equipment; sharing a Twin-port OSFP IHS/Finned Top housing alone does not make two transceiver types interoperable.
The single-mode link budget should include fiber attenuation, connectors, splices and panels over the intended 100m route. Keep the Dual MTP/MPO-12 APC interface clean and match the remote optical standard. Consider receiver overload as well as insufficient power on short links.
NVIDIA/Mellanox Compatibility and Factory Testing
The module is checked for host recognition as MMS4X00-NS, link establishment and diagnostic reporting. Physical cage fit alone is not treated as evidence of compatibility. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is -2.9~4.0dBm; the stated optical power budget is 3dB. Digital diagnostics make later maintenance easier when baseline values are captured at installation. Save the initial readings with the port and OEM reference, then investigate meaningful changes rather than reacting to a single transient value. Diagnostic support depends on the host as well as the module, so unavailable fields should be confirmed with the platform documentation. Before every insertion, keep dust caps in place until the patch lead is ready, avoid touching the optical end face and use an appropriate inspection and cleaning procedure. Do not look into an active optical interface.
Structured Fiber Pathways and Serviceability
Treat the transceiver as part of the complete channel. Follow the intended patch-panel route, maintain bend control and leave service access around the port. Confirm connector polish and fiber type at every mated pair; a documented service allowance is preferable to excess slack concealed inside a rack. For this model, the principal parameters are data rate 850Gbps (8x 106.25Gbps), wavelength 1310nm, rated reach 100m.
Ordering Information
Use MMS4X00-NS as the compatibility cross-reference and OSFP-DR8L-800G as the HT ordering identity. Keep other reaches or wavelength directions on separate order lines. Neutral labels, customer packaging and project-specific compatibility review are available on request.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.
Quality Assurance and Packaging
Each MMS4X00-NS compatible module is inspected, powered up and functionally checked before protective packing. Dust caps and individual trays shield the interface during transport. Customer references, rack groups and project packing lists can be added for volume orders.
Frequently Asked Questions
Is this an original NVIDIA/Mellanox transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies MMS4X00-NS, not an original NVIDIA/Mellanox-branded module.
Which fiber and connector are required?
Use Dual MTP/MPO-12 APC with SMF. The specified maximum reach is 100m, subject to fiber quality and total link loss.
Can it be mixed with another wavelength or reach version?
Only when the two ends share the same optical standard, wavelength plan and supported data rate. Check the exact part numbers and link budget rather than relying only on the module form factor.
