Applications and Deployment

Typical deployments include switch-to-switch, switch-to-server and aggregation links inside a data hall or between adjacent equipment rooms. The MTP/MPO-12 Male 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 40G interface configuration must match the remote equipment; sharing a QSFP+ housing alone does not make two transceiver types interoperable.

Intel Compatibility and Testing

The module is programmed for equipment that recognizes the E40GQSFPSR part number. Before shipment, we check EEPROM identification, link establishment and diagnostic readouts, then verify transmit and receiver performance against the stated optical specifications. Host hardware and software revisions can affect third-party module acceptance, so customers can provide the switch model and software release for a compatibility check before ordering.

Ordering Information

Quote HT part number QSFP-SR4-40G together with OEM part number E40GQSFPSR and the required quantity. Standard modules use our factory label; neutral labels, customer-branded packaging and project-specific compatibility coding are available on request. For mixed-brand installations, select the corresponding brand-specific page instead of assuming one EEPROM version fits every platform.

Frequently Asked Questions

Is this an original Intel transceiver?

No. It is an HT-manufactured compatible alternative for equipment that specifies E40GQSFPSR, not an original Intel-branded module.

Which fiber and connector are required?

Use MTP/MPO-12 Male with MMF. The specified maximum reach is 150m on OM4 / 100m on OM3, 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.

Quality Assurance and Packaging

Each unit undergoes optical performance checks, compatibility verification and visual inspection before packing. Modules are supplied in protective blister trays or anti-static packaging and then cartoned for transport. Custom labels and project packing lists can be added for volume orders.

Shipping and Lead Time

Standard products normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
