NVIDIA 100GBE 30AWG QSFP28 Passive Twinax Copper Cable

The NVIDIA MCP1600-E001E30 is a QSFP28 direct attach cable that measures 1 meter and uses passive Twinax copper to deliver 100Gb/s links for InfiniBand EDR as well as Ethernet systems.

Data travels through four 25Gb/s lanes inside 30AWG conductors, and the assembly follows the SFF-8665 mechanical and SFF-8636 management standards. A built-in EEPROM reports length and capabilities to the host, which simplifies inventory tracking and automatic configuration. The low smoke zero halogen jacket meets RoHS requirements, so the cable can be routed confidently in enclosed racks or densely populated data halls.

Typical uses include linking a top-of-rack switch to servers, building spine-to-leaf connections, wiring storage arrays, or connecting GPU clusters where devices sit within a short distance but need full bandwidth. Installation requires nothing more than seating each QSFP28 connector; the passive design draws no power and introduces minimal complexity.

The one meter reach keeps insertion loss within specification, helping network teams preserve throughput on critical links without the cost or power draw of optical transceivers. For data center managers who want dependable 100Gb/s performance inside the rack, this direct attach option provides a straightforward solution.
