Specifications

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 800G interface configuration must match the remote equipment; sharing a QSFP-DD housing alone does not make two transceiver types interoperable.

Before commissioning, measure the complete single-mode channel against the stated budget for 2km. Inspect every Dual Duplex LC/UPC connection and record diagnostic power where supported. Both ends must agree on rate, wavelength and optical standard.

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 -3.2~4.4dBm; the stated optical power budget is 4dB. 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. 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 1271nm, 1291nm, 1311nm and 1331nm, rated reach 2km.

Ordering Information

Quote HT part number QDD-2FR4-800G together with OEM reference QSFPDD-800G-2FR4-WDM1300-DLC 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.

H3C Compatibility and Factory Testing

Compatibility testing for QSFPDD-800G-2FR4-WDM1300-DLC 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.
