The 400G QSFP-DD to 2 x 200G QSFP56 Passive Copper Breakout DAC Cable provides a 400Gbps copper connection between QSFP-DD to 2 QSFP56 ports with a cable length of Customized. 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.

In 400G Ethernet data center and cloud network environments, the 400G QSFP-DD to 2 x 200G QSFP56 Passive Copper Breakout DAC Cable provides a factory terminated 400Gbps link between QSFP-DD to 2 QSFP56 ports. Ordered in customized lengths, it matches the actual rack geometry without slack. It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.

Compliance: IEEE802.3Bj, By, IEEE802.3CD, SFF-8679, SFF-8636. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

This cable is built to order in customized lengths. Our part number QDD-400G-2QPCxxx identifies the configuration. When placing an order, tell us the length you need and any label or packaging requirements.

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.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.

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.

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.
