NVIDIA Passive Copper Splitter Cable IB 200Gb/s QSFP56 to 2x QSFP56 3m

The NVIDIA Passive Copper Splitter Cable IB is a high-performance Direct Attach Copper (DAC) splitter cable designed for InfiniBand HDR (High Data Rate) networks. It enables a single QSFP56 port to split into two QSFP56 ports, providing flexible connectivity for high-performance computing (HPC), data centers, and AI/ML infrastructure. With a data rate of 200Gb/s and a length of 3 meters (10 feet), this passive copper cable ensures reliable, low-latency transmission without active electronics.

Advantages

This splitter cable simplifies network topology by allowing one switch port to connect to two endpoints, reducing the number of required switch ports and lowering overall system cost. The passive design ensures zero power consumption (<0.1W) and high reliability, while the 30 AWG copper construction with PVC jacket provides durability and flexibility for dense cable management.
