800G QSFP-DD QDD AC Active DAC Cable

The 800G QSFP-DD QDD AC Active DAC Cable, 1m is a active dac (acc) direct attach copper cable with QSFP-DD to QSFP-DD, supporting 800Gbps links over a length of 1m (3ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. It is a cost effective, low latency interconnect for 800G Ethernet data center and cloud network environments, and complies with 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: 5 standard options from 0.5m (2ft) to 2.5m (8ft)

Designed for 800G Ethernet data center and cloud network environments, the 800G QSFP-DD QDD AC Active DAC Cable, 1m carries 800Gbps between QSFP-DD to QSFP-DD interfaces. This unit is available in 5 standard lengths from 0.5m (2ft) to 2.5m (8ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. 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.

Standards compliance covers QSFP-DD MSA Rev. 5.0, CMIS Rev 4.0, SFF 8417, IEEE 802.3ck. The unit works in any equipment with a standard QSFP-DD to QSFP-DD interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

The standard part number of this assembly is QDD-800G-AC. We supply this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft) and 2.5m (8ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 30AWG. Volume pricing is available for project quantities.

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.

From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.

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.
