About the MCP1600-E003E30
The NVIDIA MCP1600-E003E30 LinkX passive direct attach copper cable provides 100Gbps point-to-point connections across 3 meters of twinaxial conductor. It features 4 high-speed channels operating at 25Gb/s each, providing 100Gbps bidirectional throughput with near-zero latency and zero electrical power draw. It is widely utilized for top-of-rack server and storage cabling in enterprise cloud environments.
Compatibility
Compatible with NVIDIA Spectrum 100GbE switches, such as the SN4600C and SN3700C, as well as ConnectX-4 and ConnectX-5 adapters. It supports both 100GbE Ethernet and EDR 100Gb/s InfiniBand protocols, functioning reliably across heterogeneous server installations.
How to identify a genuine unit
Equipped with black twinax cable jacket, flexible strain reliefs, and cast metal QSFP28 connector heads with black pull-release tabs. The serialized flag label displays part number MCP1600-E003E30, length, and manufacturing tracking codes. Pre-programmed EEPROMs on both ends authenticate with switch operating systems.
Buying used
Inspect the cable outer insulation for pinches, twists, or sharp bends that could compromise twinax shielding. Insert both connector heads into switch ports to confirm that the latches snap in securely and that switch diagnostic tools report error-free 100Gbps operation.
