800G QSFP-DD QDD PC Passive DAC

The 800G QSFP-DD QDD PC Passive DAC, 0.5m provides an 800Gbps copper connection between QSFP-DD to QSFP-DD ports with a cable length of 0.5m (2ft). 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.

Product Highlights

• QSFP-DD to QSFP-DD
• Data rate: 800Gbps
• Cable type: Passive DAC
• Length: 3 standard lengths between 0.5m (2ft) to 1.5m (5ft)

The 800G QSFP-DD QDD PC Passive DAC, 0.5m connects QSFP-DD to QSFP-DD ports at 800Gbps in 800G Ethernet data center and cloud network environments. This unit is provided in 3 standard lengths from 0.5m (2ft) to 1.5m (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 assembly is listed under part number QDD-800G-PC. The cable is supplied in 0.5m (2ft), 1m (3ft) and 1.5m (5ft). Custom lengths beyond the standard range are available on request. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.

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.

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.

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.
