800G QSFP-DD QDD PCxxx Passive DAC
The 800G QSFP-DD QDD PCxxx Passive DAC provides an 800Gbps copper connection between QSFP-DD to QSFP-DD ports with a cable length of 0.5~1.5m (2~5ft). As a passive cable it draws essentially no power and adds no latency to the link. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 800G Ethernet data center and cloud network environments.

Applications
The 800G QSFP-DD QDD PCxxx Passive DAC is an 800Gbps direct attach copper cable for QSFP-DD to QSFP-DD connections in 800G Ethernet data center and cloud network environments. This unit is supplied at 0.5~1.5m (2~5ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. 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.
Standards and Compatibility
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.
Ordering Information
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.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
Tested Before Shipment
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.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
