NVIDIA/Mellanox DWDM-SFP25G-10 Compatible 25G SFP28 Transceiver Module

NVIDIA/Mellanox DWDM-SFP25G-10 Compatible 25G SFP28 Transceiver Module

Built for hosts recognizing DWDM-SFP25G-10, this HT-manufactured SFP28 module delivers 25G transmission at 1563.86nm. Its rated reach is 10km on OS2, with Duplex LC/UPC as the physical interface. The specifications and engineering guidance below support mixed-vendor networks document the correct compatibility identity at each host, 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 25G interface configuration must match the remote equipment; sharing a SFP28 housing alone does not make two transceiver types interoperable.

For this 1563.86nm interface, verify channel spacing and filter compatibility. Passive filters add loss even without active equipment, so assess 10km on OS2 using the complete channel rather than fiber distance alone.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is -0.5~4.5dBm; the stated optical power budget is 18.5dB. 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.

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 25.78Gbps, wavelength 1563.86nm, rated reach 10km on OS2.

NVIDIA/Mellanox Compatibility and Factory Testing

The module is checked for host recognition as DWDM-SFP25G-10, 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 DWDM-SFP25G-10, DW-SFP25G10-17, 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

Each DWDM-SFP25G-10 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 DWDM-SFP25G-10, not an original NVIDIA/Mellanox-branded module.

Which fiber and connector are required?

Use Duplex LC/UPC with SMF. The specified maximum reach is 10km on OS2, 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.
