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 provided in 4 standard lengths from 1m (3ft) to 5m (16ft). By fanning one port out to 2x QSFP56, it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.

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.

This assembly is listed under part number QDD-400G-2QAC. The cable is supplied in 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Custom lengths beyond the standard range are available on request. 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.

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.

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.

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.
