" The optical modules and cables in this series are shipped with compatibility profiles for MikroTik and Cisco by default and have been tested in relevant device environments.
If you require compatibility with other equipment brands, we recommend informing us of the device model before placing an order so the appropriate compatibility configuration can be arranged."
The MK-TW-QDD-101 is a 400Gbps QSFP-DD Direct Attach Copper (DAC) cable featuring a Passive Twinax copper design with a length of 1 meter, ideal for short-distance ultra high-speed connections between networking equipment.
DAC (Direct Attach Copper) cables integrate QSFP-DD connector modules directly on both ends, allowing direct connection to QSFP-DD ports on switches, servers, or other networking devices. They are commonly used for in-rack device interconnection within data center racks or high-speed links between adjacent equipment.
Compared with optical transceiver solutions, DAC cables provide advantages such as lower latency, lower power consumption, and reduced deployment cost, making them particularly suitable for short-distance high-speed connectivity in modern data centers and high-performance network environments.
This cable uses 30AWG Twinax copper wiring with a passive architecture, delivering stable and reliable 400Gbps ultra high-speed data transmission, suitable for deployment between high-performance switches, servers, AI computing clusters, and data center networking infrastructure.
