800G QSFP-DD QDD AC Active DAC Cable

For short reach 800Gbps links in 800G Ethernet data center and cloud network environments, the 800G QSFP-DD QDD AC Active DAC Cable, 1m offers a factory terminated active dac (acc) assembly with QSFP-DD to QSFP-DD connectors and a length of 1m (3ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. The cable meets QSFP-DD MSA Rev. 5.0, CMIS Rev 4.0, SFF 8417, IEEE 802.3ck.

Product Highlights

• QSFP-DD to QSFP-DD
• Data rate: 800Gbps
• Cable type: Active DAC (ACC)
• Length: available from 0.5m (2ft) to 2.5m (8ft) in 5 standard options

The 800G QSFP-DD QDD AC Active DAC Cable, 1m connects QSFP-DD to QSFP-DD ports at 800Gbps in 800G Ethernet data center and cloud network environments. This unit is supplied in 5 standard lengths from 0.5m (2ft) to 2.5m (8ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs PAM4 modulation, which keeps it aligned with current 800G switch silicon.

This product is designed and tested to comply with QSFP-DD MSA Rev. 5.0, CMIS Rev 4.0, SFF 8417, 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 carries part number QDD-800G-AC. You can order this assembly in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft) and 2.5m (8ft). Non-standard lengths can be produced on request. Wire gauge: 30AWG. Volume pricing is available for project quantities.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

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.

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.

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.
