NVIDIA/Mellanox MMA4Z00-NS-FLT Compatible 800G Twin-port OSFP RHS/Flat Top Transceiver Module

NVIDIA/Mellanox MMA4Z00-NS-FLT Compatible 800G Twin-port OSFP RHS/Flat Top Transceiver Module

Built for hosts recognizing MMA4Z00-NS-FLT, this HT-manufactured Twin-port OSFP RHS/Flat Top module delivers 800G transmission at 850nm. Its rated reach is 30m on OM3 / 50m on OM4&OM5, with Dual MTP/MPO-12 APC as the physical interface. The specifications and engineering guidance below support high-density deployments balance optical performance, port access and thermal planning, while keeping HT manufacture separate from the OEM cross-reference.

Applications and Optical Link Design

Typical deployments include switch-to-switch, switch-to-server and aggregation links inside a data hall or between adjacent equipment rooms. The Dual MTP/MPO-12 APC interface connects to the specified multimode cabling, and the stated reach depends on fiber grade and link loss. Keep this interface on the matching multimode optical standard rather than connecting it directly to a single-mode wavelength or reach variant.

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 RHS/Flat Top housing alone does not make two transceiver types interoperable.

For this multimode module, confirm fiber grade, modal bandwidth and total loss before commissioning. The 30m on OM3 / 50m on OM4&OM5 figure applies only under suitable cabling conditions. Inspect every Dual MTP/MPO-12 APC mating point and match the remote optical standard.

Quality Assurance and Packaging

Before packing, the module receives interface inspection, identification and link checks. Protective packaging avoids pressure on the connector and latch. Customer references, rack groups and project packing lists can be added for volume orders.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is -4.6~4dBm; the stated optical power budget is 1.7dB. 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. Diagnostic monitoring is listed as Supported. 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.

High-Density Port and Thermal Planning

In a densely populated chassis, connector access and airflow form part of the optical-link design. Confirm that neighboring modules and patch leads leave room for latch operation, and include listed power consumption in the host thermal budget. Assess port density together with fiber management. For this model, the principal parameters are data rate 850Gbps (8x 106.25Gbps), wavelength 850nm, rated reach 30m on OM3 / 50m on OM4&OM5.

Ordering Information

Quote HT part number OSFP-SR8-800G-FL together with OEM reference MMA4Z00-NS-FLT and quantity. Add the host model and software release when pre-order verification is required. Neutral labels, customer packaging and project-specific compatibility review are available on request.

NVIDIA/Mellanox Compatibility and Factory Testing

Compatibility testing for MMA4Z00-NS-FLT combines identification with a live link and available transmit, receive and alarm information. Connector condition is inspected separately. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.

Frequently Asked Questions

Is this an original NVIDIA/Mellanox transceiver?

No. It is an HT-manufactured compatible alternative for equipment that specifies MMA4Z00-NS-FLT, not an original NVIDIA/Mellanox-branded module.

Which fiber and connector are required?

Use Dual MTP/MPO-12 APC with MMF. The specified maximum reach is 30m on OM3 / 50m on OM4&OM5, 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.

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.
