About the MCP1650-H003E30
The NVIDIA MCP1650-H003E30 LinkX passive copper twinax cable delivers 200Gb/s HDR InfiniBand and 200GbE connectivity over a 3-meter reach. Using 4 channels of 50Gb/s PAM4 signaling, it provides high transmission density with low latency and zero transceiver power consumption. It is engineered for intra-rack server connections in high-performance computing and machine learning clusters.
Compatibility
Supported on NVIDIA Quantum QM8700 and QM8790 switches, Spectrum SN4600 Ethernet switches, and ConnectX-6 adapters. It enables direct host-to-switch and switch-to-switch links within data center server racks without requiring optical transceiver infrastructure.
How to identify a genuine unit
Features high-frequency twinaxial cabling encased in a black protective jacket with blue pull-release latches. The flag label shows part code MCP1650-H003E30, length specification, and serial barcode. Embedded EEPROM chips on both connector heads provide detailed hardware telemetry to management tools.
Buying used
Check that both connector shells are straight and free from bent pins or mechanical contamination. Confirm that the cable bend radius remains within the recommended 5x cable diameter specification. Verify that the link establishes full 200Gbps line rate upon connection.
