56Gb/s QSFP Infiniband FDR Passive Direct Attach Copper Cable (QSFP Passive DAC) The QSFP-56G-DACxM direct attach copper cable assembly (also known as DAC) is suitable for very short distances and offers a highly cost-effective way to establish a 56 Gigabit link connectivity between devices using QSFP ports. The QSFP DAC cable is designed for 56Gb/s InfiniBand FDR interconnecting networking applications such as high-performance computing (HPC), enterprise networking including top-of-rack switching and network storage markets. The QSFP-56G-DACxM fully complies with QSFP Multi-Source Agreement (MSA) standards SFF-8436 and InfiniBand FDR specifications. It is developed specifically as a cost-effective and lower-power alternative to 56G QSFP optics and 56G QSFP active optical fiber cable (QSFP AOC). Features • Lower cost than 56G QSFP optics and active optical cable (AOC) • Maximum aggregate data rate: 56 Gb/s (4 x 14Gb/s) • Hot-pluggable QSFP 38-PIN footprint • Single 3.3V power supply • Compliant with QSFP MSA SFF-8436 • Compliant with Infiniband QDR/DDR/FDR data rates • Operating temperature range: 0 to 70°C • RoHS Compliant and Lead-Free Specification Product Series Direct Attach Copper Cable Optcore Part Number QSFP-56G-DACxM Form Factor QSFP DAC Cable Data Rate 56 Gb/s Passive or actively equalized Passive Supply Voltage 3.3 V Cable Length 0.5~5 meter Cable impedance 100 Ω Cable Type Twinax Wire Gauge 24/26/28AWG Minimum cable bend radius 35 mm Cable Jacket Type PVC Connector QSFP /QSFP Digital Diagnostic Monitoring N/A Environment Operating: 0°C to 70°C Storage: -40°C to 85°C Weight 0.2~0.6 kg Application InfiniBand FDR 16x Fibre Channel Proprietary high-speed interconnections Data center cabling infrastructure Compliance InfiniBand SDR/DDR/QDR SFF-8436, RoHS Ordering Information Part number Description QSFP-56G-DAC05M 56G QSFP Passive Direct Attach Copper Cable (DAC), 0.5m, AWG28 QSFP-56G-DAC1M 56G QSFP Passive Direct Attach Copper Cable (DAC), 1m, AWG28 QSFP-56G-DAC2M 56G QSFP Passive Direct Attach Copper Cable (DAC), 2m, AWG28 QSFP-56G-DAC3M 56G QSFP Passive Direct Attach Copper Cable (DAC), 3m, AWG26 QSFP-56G-DAC4M 56G QSFP Passive Direct Attach Copper Cable (DAC), 4m, AWG24 QSFP-56G-DAC5M 56G QSFP Passive Direct Attach Copper Cable (DAC), 5m, AWG24 Download Datasheet Note: Specifications and product availability are subject to change without notice.
