Applications
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. Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.
Standards and Compatibility
This product is designed and tested to comply with IEEE802.3Bj, By, IEEE802.3CD, SFF-8679, SFF-8636. It plugs into any standards-based QSFP-DD to 2 QSFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
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. Volume pricing is available for project quantities.
How We Ship
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.
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.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
Custom-made Fiber Products
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.
