Applications
The 400G QSFP-DD to 2 x 200G QSFP56 Passive Copper Breakout DAC Cable connects QSFP-DD to 2 QSFP56 ports at 400Gbps in 400G Ethernet data center and cloud network environments. 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. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.
Standards and Compatibility
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.
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.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
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.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
Shipping and Lead Time
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.
