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

Juniper Networks 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 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

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.

For this multimode module, confirm fiber grade, modal bandwidth and total loss before commissioning. The 30m on OM3 / 50m on OM4 figure applies only under suitable cabling conditions. Inspect every MTP/MPO-16 APC mating point and match the remote optical standard.

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.

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 850Gbps (8x 106.25Gbps), wavelength 850nm, rated reach 30m on OM3 / 50m on OM4.

Juniper Networks 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.

Ordering Information

Quote HT part number QDD-SR8-800G together with OEM reference QDD-SR8-800G and quantity. Add the host model and software release when pre-order verification is required. Neutral labels, customer packaging and project-specific compatibility review are available on request.

Quality Assurance and Packaging

Each QDD-SR8-800G 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 Juniper Networks transceiver?

No. It is an HT-manufactured compatible alternative for equipment that specifies QDD-SR8-800G, not an original Juniper Networks-branded 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.
