BlueLAN 200Gb/s QSFP56 to 2x100Gb/s QSFP56 Infiniband HDR Direct Attach Breakout Cable, 3m, AWG26 (MCP7H50-H003R26-BL)

Transmit 200Gb/s across two 100Gb/s Infiniband HDR links with this passive QSFP56 to dual QSFP56 direct attach breakout cable. Built for data centers and HPC clusters, it delivers PAM4-modulated copper twinax performance over a 3-meter AWG26 run.

Overview

The BlueLAN MCP7H50-H003R26-BL is a passive Direct Attach Breakout Cable (DAC) engineered for NVIDIA Infiniband HDR environments. It features a QSFP56 connector on one end and two QSFP56 connectors on the other, supporting an aggregate data rate of 200Gb/s (2×100Gb/s). The cable is hot-swappable and uses PAM4 modulation over copper twinax media, ensuring low latency and high reliability for high-performance computing, enterprise networking, and data center interconnects.
