400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Active Breakout DAC Cable, 5m

The 400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Active Breakout DAC Cable, 5m is a active direct attach copper cable with QSFP-DD to 2x QSFP56, supporting 400Gbps links over a length of 5m (16ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. It is a cost effective, low latency interconnect for 400G Ethernet data center and cloud network environments, and complies with QSFP-DD MSA, SFF-8636, SFF-8679.

Applications
In 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 provides a factory terminated 400Gbps link between QSFP-DD to 2x QSFP56 ports. This unit is made 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. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.
Standards and Compatibility
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.
Ordering Information
The part number for this assembly is QDD-400G-2QAC. We offer this cable in 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Other lengths can be custom manufactured on request. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.
Packaging
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.
Customization Service
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.
Logistics
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.
Reliability Control
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.
