800G QSFP-DD QDD PCxxx Passive DAC

For short reach 800Gbps links in 800G Ethernet data center and cloud network environments, the 800G QSFP-DD QDD PCxxx Passive DAC offers a factory terminated passive dac assembly with QSFP-DD to QSFP-DD connectors and a length of 0.5~1.5m (2~5ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets QSFP-DD MSA, CMIS Rev4.0, IEEE 802.3ck.

Product Highlights

• QSFP-DD to QSFP-DD
• Data rate: 800Gbps
• Cable type: Passive DAC
• Length: 0.5~1.5m (2~5ft)

In 800G Ethernet data center and cloud network environments, the 800G QSFP-DD QDD PCxxx Passive DAC provides a factory terminated 800Gbps link between QSFP-DD to QSFP-DD ports. This unit is supplied at 0.5~1.5m (2~5ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs 8x 100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

This product is designed and tested to comply with QSFP-DD MSA, CMIS Rev4.0, IEEE 802.3ck. It plugs into any standards-based QSFP-DD to QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

This model is supplied at 0.5~1.5m (2~5ft) under part number QDD-800G-PCxxx. Other lengths of the same assembly can be produced on request. Wire gauge: 28~30AWG.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
