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 SFP+ 10G 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 10GbE switches or similar applications.

Close to zero power consumption and a wide temperature range

SFP+ DAC is comprised of a twinax copper cable terminated with SFP+ 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 clean and inspect them before plugging them in again. When you make upgrades or replacements to your network, the cable's seamless Hot Swapping capability makes quick work of connecting new equipment (note that passive DAC cables are not suitable for long-range applications; at 7 m (23 ft.), they reach their transmission limit).

Lower latency than RJ45 twisted-pair patch cables

Like "regular" Cat6a and Cat7 copper cables, this Direct Attach Copper twinax cable supports data transfer rates up 10 Gbps, but its unique structure and signal transmission offers lower latency.

FAQ:

Q:I'm looking for this cabe but with 10 meters. Do you have one?

A:The maximum length we recommend for passive DAC is 7 meters, taking into account link loss. If you need 10-meter direct attach cables, this 

Q:What is the difference between the Passive DAC and the Active DAC?

A:Passive DAC cable contains no electronics for signal conditioning, so it has lower power consumption, but the linking distance is limited to 7m. While active DAC cable contains electrical components in the connectors, allowing reaching greater distances (up to 10m) via copper media and ensuring better transmission quality. This makes active copper cables slightly more expensive and consumes more power than direct attach passive copper cables.

Q:Can I have different compatibilities for each end of my direct attach cables?

A:Yes, you can. SEESUO.COM offers customized dual compatibility solutions for direct attach cables so that you can choose compatibilities for each end individually. All you need to do is to select "Dual Compatibility Solutions" option in Compatible Brands drop-down box and note down your devices' model numbers in custom page.

Q:What kinds of custom choices are offered in SEESUO.COM?

A:As for customized direct attach cables, SEESUO.COM offers regular custom choices such as compatibility, cable length, cable color, operating temperature, label pattern, label colors and etc. What's more, SEESUO.COM welcomes any inquiry for customized products and solutions for all need and specifications.

Which things we Should Know Before Buying DAC Cable?

1. DACs are cheaper than the regular optics. Because the “transceivers” on both ends of DACs are not real optics. Compared with the regular optics, they have no real components and just used to transmit the optical signals. Of course, without those expensive optics components, the cost of DAC twinax cable is much lower. Thus, though using the same port as an optical transceiver, DACs have significant cost savings and power savings in short reach applications.

2. The main difference between active DAC cable and passive DAC cable is that there is a driving chip in the design of active DAC. For more knowledge, please refer to Difference Between Passive and Active Twinax Cable Assembly.

3. AOC (Active Optical Cable) is one of the forms of DAC cable. It integrates multimode optical fiber, fiber optic transceivers, control chip, and modules. AOCs have many benefits such as lighter weight, high performance, low power consumption, low interconnection loss, EMI immunity, and flexibility etc. AOCs are now considered as the rising star of telecommunications and datacom transceiver in the market.
