NVIDIA/Mellanox SFP-10GZR-55 Compatible 10G SFP+ ZR Transceiver Module
Built for hosts recognizing SFP-10GZR-55, this HT-manufactured SFP+ module delivers 10G transmission at 1550nm. Its rated reach is 80km, with Duplex LC as the physical interface. The specifications and engineering guidance below support project teams keep OEM references, delivery records and port schedules aligned, while keeping HT manufacture separate from the OEM cross-reference.

Project Documentation and Traceability
Large deployments are easier to audit when the order code, optical standard and endpoint record agree. Keep the OEM reference in the compatibility document and the HT part number on the packing list. Labels and carton groups can be arranged by rack or port plan so installers need not identify modules by appearance. For this model, the principal parameters are data rate 11.3Gbps, wavelength 1550nm, rated reach 80km.
NVIDIA/Mellanox Compatibility and Factory Testing
Factory verification starts with the expected SFP-10GZR-55 identity and finishes with an operating host link. EEPROM data, diagnostic visibility and the stated optical parameters are assessed together. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.
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 10G interface configuration must match the remote equipment; sharing a SFP+ housing alone does not make two transceiver types interoperable.
For this 1550nm interface, verify channel spacing and filter compatibility. Passive filters add loss even without active equipment, so assess 80km using the complete channel rather than fiber distance alone.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is 0~5dBm; receiver sensitivity is <-23dBm. 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. 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.
Frequently Asked Questions
Is this an original NVIDIA/Mellanox transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies SFP-10GZR-55, not an original NVIDIA/Mellanox-branded module.
Which fiber and connector are required?
Use Duplex LC with SMF. The specified maximum reach is 80km, 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.
Ordering Information
When ordering, specify SFP-10GZR-55, SFP-10GZR-55, 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.
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
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.
