400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Passive Breakout DAC Cable, 2m
The 400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Passive Breakout DAC Cable, 2m provides a 400Gbps copper connection between QSFP-DD to 2x QSFP56 ports with a cable length of 2m (7ft). As a passive cable it draws essentially no power and adds no latency to the link. 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.

Applications
In 400G Ethernet data center and cloud network environments, the 400G QSFP-DD 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 Passive Breakout DAC Cable, 2m provides a factory terminated 400Gbps link between QSFP-DD to 2x QSFP56 ports. This unit is delivered in 6 standard lengths from 0.5m (2ft) to 3m (10ft). 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.
Standards and Compatibility
Standards compliance covers IEEE802.3Bj, By, IEEE802.3CD, SFF-8679, SFF-8636. 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 ordering part number is QDD-400G-2QPC. We make this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Special lengths outside this range can be produced to order. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.
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.
Packing Details
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.
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.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
