The Direct Attach Copper (DAC) cable is becoming increasingly popular in the network industry. Our passive SFP+ 10G DAC Twinax cable is an energyefficient, low-latency and cost-effective alternative to fiber optic and RJ45 cabling. It's an excellent choice for short-distance structured cabling between switches and routers on one end and servers or storage on the other, be it in Top of Rack (ToR), adjacent rack, stacking of 10GbE switches or similar applications.
