10/100BASE-T SFPIntel QSFP56-SR2-100G Compatible 100G QSFP56 SR2 Transceiver Module
Built for hosts recognizing QSFP56-SR2-100G, this HT-manufactured QSFP56 module delivers 100G transmission at 850nm. Its rated reach is 100m, with MPO-12/UPC as the physical interface. The specifications and engineering guidance below support structured fiber installations preserve a documented and serviceable optical channel, 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 MPO-12/UPC 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 100G interface configuration must match the remote equipment; sharing a QSFP56 housing alone does not make two transceiver types interoperable.
The multimode channel should use the fiber grade associated with the stated 100m reach. Keep the MPO-12/UPC end faces clean and avoid tight bends. Different multimode standards are not interchangeable merely because they share a connector.
Intel Compatibility and Factory Testing
Compatibility testing for QSFP56-SR2-100G 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.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is -6.5~4dBm; the stated optical power budget is 1.9dB. During commissioning, record the host diagnostic readings after the link has stabilized and compare them with those limits. DOM values are useful operational indicators, but they do not replace calibrated optical measurements when a link is marginal. Investigate unexpected loss through connector inspection, cleaning and a channel measurement before replacing the module. 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.
Structured Fiber Pathways and Serviceability
Treat the transceiver as part of the complete channel. Follow the intended patch-panel route, maintain bend control and leave service access around the port. Confirm connector polish and fiber type at every mated pair; a documented service allowance is preferable to excess slack concealed inside a rack. For this model, the principal parameters are data rate 106.25 Gbps, wavelength 850nm, rated reach 100m.
Ordering Information
When ordering, specify QSFP56-SR2-100G, QSFP56-SR2-100G, 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
Each QSFP56-SR2-100G 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 Intel transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies QSFP56-SR2-100G, not an original Intel-branded module.
Which fiber and connector are required?
Use MPO-12/UPC with MMF. The specified maximum reach is 100m, 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.
