The 400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Active Breakout DAC Cable, 5m is a 400Gbps active copper cable for QSFP-DD to 2x QSFP56 connections in 400G Ethernet data center and cloud network environments. This unit is stocked in 4 standard lengths from 1m (3ft) to 5m (16ft). One port becomes 2x QSFP56, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

Standards compliance covers QSFP-DD MSA, SFF-8636, SFF-8679. The unit works in any equipment with a standard QSFP-DD to 2x QSFP56 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

Order reference: part number QDD-400G-2QAC. Standard supply covers 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Custom length production is available for project requirements. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.

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.

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.

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
