400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Active Breakout DAC Cable

The 400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Active Breakout DAC Cable, 5m provides a 400Gbps copper connection between QSFP-DD to 2x QSFP56 ports with a cable length of 5m (16ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 400G Ethernet data center and cloud network environments.

The 400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Active Breakout DAC Cable, 5m connects QSFP-DD to 2x QSFP56 ports at 400Gbps in 400G Ethernet data center and cloud network environments. This unit is supplied in 4 standard lengths from 1m (3ft) to 5m (16ft). The breakout design lets one high speed port feed 2x QSFP56, which raises port utilization and simplifies cabling in dense rows. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

Compliance: QSFP-DD MSA, SFF-8636, SFF-8679. 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.

This model carries part number QDD-400G-2QAC. You can order this assembly in 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Non-standard lengths can be produced on request. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.

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.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
