Description
The NVIDIA Mellanox MCP1650-H002E26 is a 2m passive direct attach copper cable for 200Gb/s InfiniBand HDR. It links two QSFP56 ports. It contains eight high-speed copper pairs, each running at up to 50Gb/s, and uses 4x 50Gb/s PAM4 modulation.
As a power-efficient alternative to optical links for short distances, this cable draws a maximum of 0.1W and is rated for a BER better than 1E-15 with Mellanox InfiniBand HDR systems. The 26AWG cable has an LSZH jacket and a black pulltab. Each QSFP56 end includes an EEPROM that the host can read through an SFF-8636 compliant I²C interface.
