Specifications

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 425G interface configuration must match the remote equipment; sharing a QSFP112 housing alone does not make two transceiver types interoperable.

Before commissioning, measure the complete single-mode channel against the stated budget for 500m. Inspect every MPO-12/APC connection and record diagnostic power where supported. Both ends must agree on rate, wavelength and optical standard.

Quality Assurance and Packaging

Quality control covers the optical or electrical interface, host identification and operating link. The verified unit is then individually protected and cartoned. 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 -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. 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.

Data-Center Optical Design and Airflow

Select the module by optical standard, reach and rack layout. Check the complete fiber channel, including panels and connectors, and keep dense bundles from blocking front-panel airflow. Account for listed power consumption and preserve enough space to remove a module without disturbing adjacent links. For this model, the principal parameters are data rate 425Gbps (4x106.25Gb/s), wavelength 1310nm, rated reach 500m.

Ordering Information

Use MMS1X00-NS400 as the compatibility cross-reference and QSFP112-DR4-400G 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.

NVIDIA/Mellanox Compatibility and Factory Testing

Compatibility testing for MMS1X00-NS400 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.
