Generic Compatible 400G QSFP-DD Direct Attach Copper Twinax Cable (1-meter, Passive, 30AWG) The QDD-400G-DAC-PxM direct attach copper cable assembly (also known as QSFP-DD DAC) is suitable for very short links and offers a highly cost-effective way to establish a 400 Gigabit link connectivity between devices using QSFP-DD ports. It is developed specifically as a cost-effective and lower-power replacement to 400G QSFP-DD SR8 transceiver optics and QSFP-DD active optical fiber (400G QSFP-DD AOC) for very short distances. Features • QSFP-DD MSA compliant • Up to 400Gb/s data rate • 8 x 50Gb/s PAM4 modulation • SFF-8636 compliant I2C management interface • Up to 3m transmission • Single 3.3V power supply • Low insertion loss • RoHS Compliant and Lead-Free Specification Product Series 400G QSFP-DD DAC Cable Optcore Part Number QDD-400G-DAC1M Form Factor QSFP-DD to QSFP-DD Data Rate 400 Gb/s Passive or actively equalized Passive Supply Voltage 3.3V Cable Length 1 meter Cable impedance 100 Ω Cable Type Twinax Wire Gauge 30AWG Minimum cable bend radius 35 mm Cable Jacket Type PVC Connector QSFP-DD/QSFP-DD Digital Diagnostic Monitoring N/A Environment Operating: 0°C to 70°C Storage: -40°C to 85°C Weight 0.4 kg Application Switches, servers, and routers Data Center networks Storage area networks High-performance computing Telecommunication and network infrastructure Fibre Channel over Ethernet Compliance IEEE802.3bj SFF-8679, SFF-8636, RoHS Ordering Information Part number Description QDD-400G-DAC05M 400G QSFP-DD Direct Attach Copper Cable, Passive, 0.5m, AWG30 QDD-400G-DAC1M 400G QSFP-DD Direct Attach Copper Cable, Passive, 1m, AWG30 QDD-400G-DAC2M 400G QSFP-DD Direct Attach Copper Cable, Passive, 2m, AWG28 QDD-400G-DAC3M 400G QSFP-DD Direct Attach Copper Cable, Passive, 3m, AWG26 Download Datasheet Note: Specifications and product availability are subject to change without notice.
