400G QSFP-DD to 4 x 100G QSFP56 Active400G 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 provides a 400Gb/s copper connection between QSFP-DD to 4xQSFP56 ports with a cable length of 3-7m. Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. 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.

Applications
The 400G QSFP-DD to 4 x 100G QSFP56 Active Copper Breakout DAC Cable is a 400Gb/s active copper cable for QSFP-DD to 4xQSFP56 connections in 400G Ethernet data center and cloud network environments. 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. The link runs PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: QSFP-DD MSA 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 model is supplied at 3-7m under part number QDD-400G-4QACxxx. Other lengths of the same assembly can be produced on request.
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.
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
