Product overview

The benefits of Passive Direct Attach Copper (DAC) cable over fiber optic and RJ45 cables. The Direct Attach Copper (DAC) cable is becoming increasingly popular in the network industry. Our passive QSFP+ 40G DAC Twinax cable is an energy-efficient, 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 40GbE switches or similar applications. Close to zero power consumption and a wide temperature range. QSFP+ DAC is comprised of a twinax copper cable terminated with QSFP+ connectors on both ends, which can provide an electrical connection directly into active equipment. Consuming less than 0.15 W due to its thermal design, this passive cable helps decrease your operating expenses. Its zero-heat production during operation makes it more versatile and usable in wider temperature ranges up to 70°C (158°F), which is particularly valuable in data centers. Lower cost and simpler to deploy than fiber optics. DAC cabling has a relatively simple internal structure with fewer components than fiber cables. This cable structure helps lower the purchase price for applications in high-bandwidth data transmission and saves you from having to buy separate transceivers. This, in turn, makes DAC cables a lot simpler to deploy since there are fewer parts to match to complete setup. Used versions of this cable are also more convenient to keep on hand because you do not have to...
