25G SFP28 DAC Cable (Passive, SFP28 to SFP28, 0.5~5 meter) Optcore’s SFP-25G-DACxM is a hot-swappable passive direct attach copper cable assembly (also known as Twinax Cable or DAC) with SFP28 modules at both ends. It is developed specifically as a cost-effective and lower-power alternative to 25Gb SFP28 optics and Active Optical Cables (AOC), to meet the increasing needs of higher bandwidth in data centers. The 25G SFP28 DAC cable fully complies with SFP28 Multi-Source Agreement (MSA) standards SFF-8402 and SFF-8432 specifications. It is designed for very short reach links in 25Gbps high-speed I/O interconnect applications such as high-performance computing (HPC) and high-density data center. Features • Up to 25Gb/s data rate • Compliant with SFF-8402 and SFF-8432 • Compatible to SFP MSA SFF-8431 • Hot-pluggable SFP 20PIN footprint • Lowest total system EMI solution • Low insertion loss and low crosstalk • Single 3.3V power supply • Operating temperature range: 0 to 70°C • RoHS Compliant and Lead-Free Specification Product Series Direct Attach Copper Twinax Cable Optcore Part Number SFP-25G-DACxM Form Factor 25G SFP28 DAC Data Rate 25 Gb/s Passive or actively equalized Passive Supply Voltage 3.3V Cable Length 0.5~5 m Cable impedance 100 Ω Cable Type Twinax Wire Gauge 24/26/30AWG Minimum cable bend radius 35 mm Cable Jacket Type PVC Connector SFP28/SFP28 Digital Diagnostic Monitoring N/A Environment Operating: 0°C to 70°C Storage: -40°C to 85°C Weight 0.1~0.4 kg Application 25G Ethernet Data center cabling infrastructure Compliance SFF-8402 SFF-8432 MIL-STD-883C RoHS Ordering Information Part number Description SFP-25G-DAC05M 25G SFP28 DAC Cable(Passive Direct Attach Copper Cable), 0.5m, AWG30 SFP-25G-DAC1M 25G SFP28 DAC Cable(Passive Direct Attach Copper Cable), 1m, AWG30 SFP-25G-DAC2M 25G SFP28 DAC Cable(Passive Direct Attach Copper Cable), 2m, AWG30 SFP-25G-DAC3M 25G SFP28 DAC Cable(Passive Direct Attach Copper Cable), 3m, AWG26 SFP-25G-DAC4M 25G SFP28 DAC Cable(Passive Direct Attach Copper Cable), 4m, AWG26 SFP-25G-DAC5M 25G SFP28 DAC Cable(Passive Direct Attach Copper Cable), 5m, AWG24 Download Datasheet Note: Specifications and product availability are subject to change without notice.
