QSFPDD – QSFPDD DAC 400GE 0.5m-2.5m CMIS4
A passive Direct Attach Copper (DAC) for 400G Ethernet applications
Product information
The DQD003-xxxC-SO is an active Direct Attach Cable (DAC) solution of Twinax type, i.e. a copper cable similar to coaxial cable, but with two inner conductors instead of one. DQD003-xxxC-SO is a solution for 400Gbps connections within racks and across adjacent racks where the interconnected equipment uses QSFP-DD interfaces. It provides a cost-efficient solution as compared to using optical transceivers and it simplifies the patching since no separate transmit/receive direction has to be taken into account.
The electrical interface of the module is compliant with the electrical interfaces 4x100GAUI-2 and 400GAUI-8 as well as the QSFP-DD MSA.
DQD003-xxxC-SO integrates eight data lanes (25Gbd) in each direction using PAM4 modulation with 400Gbps aggregate bandwidth.The DQD003-xxxC-SO cables have an I2C interface with Integrated Digital Diagnostic Monitoring according to the Common Management Interface Specification CMIS 4.0.
The DQD003-xxxC-SO is provided in lengths from 0.5 to 2.5 meters (1.6 to 8.2 ft).
