Description
The AddOn Mellanox® MCP1660-W02AE26-AO is a high-performance 400GBase-CU QSFP-DD to QSFP-DD direct attach copper cable designed for reliable, high-speed data transmission in next-generation data centers and enterprise networks. This passive twinax DAC supports a maximum reach of 2.5 meters (8.2 ft) and is fully compliant with IEEE 802.3bs and QSFP-DD MSA standards.
Each cable is programmed, uniquely serialized, and rigorously tested for data traffic and application compatibility, ensuring seamless interoperability with Mellanox® networking equipment. The hot-pluggable design simplifies installation and upgrades, while built-in EEPROM functions enhance device communication and monitoring. Additionally, this DAC is TAA (Trade Agreements Act) compliant, RoHS compliant, and lead-free, making it ideal for government, defense, and enterprise applications requiring secure and standards-compliant infrastructure.
