WINET QDD-400G-2QDAC Passive Copper Breakout Direct Attach Cable

Overview: The WINET QDD-400G-2QDAC series is a passive Twinax copper breakout DAC cable designed for high-speed data transmission. This cable splits a 400G QSFP-DD port into two 200G QSFP56 ports, providing a total bandwidth of 400 Gbps. It is suitable for short-distance connections and operates with low power consumption. Available in 1 meter and 2 meter lengths, this cable is hot-pluggable and compatible with QSFP-DD and QSFP56 interfaces. It features controlled impedance and low crosstalk design. Key Features: - Passive DAC breakout configuration from 400G QSFP-DD port to 2×200G QSFP56 ports - Total data rate of 400 Gbps - Passive Twinax copper cable for short-distance connections - Low power consumption: 0.1 W per connector end - Length options: 1 m and 2 m - Hot-pluggable QSFP-DD and QSFP56 interfaces - Controlled impedance and low crosstalk design Technical Summary: Model Codes: QDD-400G-2QDAC1M, QDD-400G-2QDAC2M Product Type: Passive DAC Breakout Cable Connector Configuration: 1× QSFP-DD → 2× QSFP56 Total Data Rate: 400 Gbps Data Rate per Port: 200 Gbps Breakout Ratio: 1:2 Cable Type: Passive Twinax Copper Cable Length: 1 m, 2 m Cable AWG: 28 AWG, 30 AWG Minimum Bend Radius: 39.5 mm Jacket Material: PVC Power Consumption: 0.1 W per connector end Operating Temperature: -20 to +75 °C Storage Temperature: -40 to +80 °C IEEE Standards: IEEE 802.3bj, 802.3by, 802.3cd; SFF-8679, SFF-8636 Cable Impedance: 105 +5/-10 Ω Paddle Card Differential Impedance: 100 ±10 Ω Cable Termination Impedance: 100 ±15 Ω Low-Level Contact Resistance: Maximum 70 mΩ Insulation Resistance: Minimum 10 MΩ Dielectric Withstand Voltage: 300 VDC Cable Flexing: 180°; 20 cycles; 1 kg load Retention Force in Cage: Minimum 90 N Retention Force in Plug: Minimum 90 N Mechanical Shock: 100 g, 6 ms; 3 times in 6 directions Durability: 50 mating/unmating cycles
