Generic QDD-SR8-800G Compatible 800G QSFP-DD SR8 Transceiver Module 30m on OM3 / 50m on OM4

Generic QDD-SR8-800G Compatible 800G QSFP-DD SR8 Transceiver Module 30m on OM3 / 50m on OM4

Built for hosts recognizing QDD-SR8-800G, this HT-manufactured QSFP-DD module delivers 800G transmission at 850nm. Its rated reach is 30m on OM3 / 50m on OM4, with MTP/MPO-16 APC as the physical interface. The specifications and engineering guidance below support data-center designers evaluate optical reach, rack integration and host compatibility together, 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 MTP/MPO-16 APC 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 800G interface configuration must match the remote equipment; sharing a QSFP-DD housing alone does not make two transceiver types interoperable.

The multimode channel should use the fiber grade associated with the stated 30m on OM3 / 50m on OM4 reach. Keep the MTP/MPO-16 APC end faces clean and avoid tight bends. Different multimode standards are not interchangeable merely because they share a connector.

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.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is -4.6-4dBm; the stated optical power budget is 1.8dB. 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. 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 850Gbps (8x 106.25Gbps), wavelength 850nm, rated reach 30m on OM3 / 50m on OM4.

Ordering Information

When ordering, specify QDD-SR8-800G, QDD-SR8-800G, 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.

Generic Compatibility and Factory Testing

The module is checked for host recognition as QDD-SR8-800G, 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.

Frequently Asked Questions

Is this an original equipment manufacturer transceiver?

No. It is an HT-manufactured compatible transceiver supplied under our own manufacturer identity, not an original equipment manufacturer module.

Which fiber and connector are required?

Use MTP/MPO-16 APC with MMF. The specified maximum reach is 30m on OM3 / 50m on OM4, 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.
