Specifications

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.

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. A sound acceptance record includes link state, diagnostic temperature, supply voltage and transmit or receive levels where the host exposes them. Compare the readings with the stated ranges rather than treating any received light as proof of adequate margin. Persistent alarms or borderline values should trigger an end-face and complete-channel inspection. 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.

Mixed-Vendor Network Operation

A mixed-vendor optical link should be documented at both ends, not treated as one generic connection. Confirm which OEM identity each host expects and whether both ends use the same wavelength plan and optical standard. Related links locate equivalent hardware, but brand-specific identification must still be selected independently. For this model, the principal parameters are data rate 850Gbps (8x 106.25Gbps), wavelength 850nm, rated reach 30m on OM3 / 50m on OM4&OM5.

NVIDIA/Mellanox Compatibility and Factory Testing

The module is checked for host recognition as MMA4Z00-NS-FLT, 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.

Ordering Information

When ordering, specify MMA4Z00-NS-FLT, OSFP-SR8-800G-FL, quantity and intended host platform. Project labels can repeat these details for receiving and asset records. Neutral labels, customer packaging and project-specific compatibility review are available on request.

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.
