TensorJuice 400G QSFP-DD to 2× 200G QSFP56 Breakout DAC — 2m

A 400-Gigabit QSFP-DD to 2× 200G QSFP56 passive breakout direct attach cable, 2m long. Splits a single 400G switch port into two 200G links — purpose-built for fanning out a 400G uplink to a pair of NVIDIA DGX Spark / ASUS Ascent class AI nodes without burning extra switch ports.

Fully compliant with SFF-8679, QSFP-DD MSA, IEEE 802.3bj, and IEEE 802.3cd. Passive copper construction means zero added latency, no transceiver licensing, and near-zero power draw (~0.1W per end). Ideal for desktop and top-of-rack AI clusters paired with the CRS812 DDQ or CRS804 DDQ.
