400G QSFP-DD to 4 x 100G QSFP56 Active Copper Breakout DAC Cable

The 400G QSFP-DD to 4 x 100G QSFP56 Active Copper Breakout DAC Cable is a active twinax direct attach copper cable with QSFP-DD to 4xQSFP56, supporting 400Gb/s links over a length of 3-7m. 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.

Designed for 400G Ethernet data center and cloud network environments, the 400G QSFP-DD to 4 x 100G QSFP56 Active Copper Breakout DAC Cable carries 400Gb/s between QSFP-DD to 4xQSFP56 interfaces. This unit is supplied at 3-7m. By fanning one port out to 4xQSFP56, it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

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 4xQSFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

This model is supplied at 3-7m under part number QDD-400G-4QACxxx. Other lengths of the same assembly can be produced on request. Volume pricing is available for project quantities.

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.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.

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.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
