400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AEC

For short reach 400Gbps links in 400G Ethernet data center and cloud network environments, the 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AEC, 3m offers a factory terminated twinax assembly with QSFP-DD to 4x QSFP28 connectors and a length of 3m (10ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. The cable meets industry MSA standards.

Product Highlights

• QSFP-DD to 4x QSFP28

In 400G Ethernet data center and cloud network environments, the 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP28 4x 25G NRZ Breakout AEC, 3m provides a factory terminated 400Gbps link between QSFP-DD to 4x QSFP28 ports. This unit is available in a standard length of 3m (10ft). One port becomes 4x QSFP28, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

Compliance: industry MSA standards. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

The standard part number of this assembly is QDD-400G-4Q4XNAC. The standard length is 3m (10ft), and other lengths can be produced on request. Wire gauge: 30AWG. Volume pricing is available for project quantities.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

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.

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.

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
