400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 Active Breakout DAC Cable

The 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 Active Breakout DAC Cable is a active twinax direct attach copper cable with QSFP-DD to 4x QSFP56, supporting 400Gb/s links over a length of 5m. 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-8679 SFF-8636.

In 400G Ethernet data center and cloud network environments, the 400G QSFP-DD 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 Active Breakout DAC Cable provides a factory terminated 400Gb/s link between QSFP-DD to 4x QSFP56 ports. This unit is available in 3 standard lengths from 3m (10ft) to 5m (16ft). By fanning one port out to 4x 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-8679 SFF-8636. It plugs into any standards-based QSFP-DD to 4x 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-4QAC. We supply this cable in 3m (10ft), 4m (13ft) and 5m (16ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 28 AWG.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

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.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
