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 available 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. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

This product is designed and tested to comply with QSFP-DD MSA, SFF-8636, SFF-8679. It plugs into any standards-based QSFP-DD to 2x QSFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

The standard part number of this assembly is QDD-400G-2QAC. We supply this cable in 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 28AWG.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

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.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.

We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
