✅100% perfect compatibility: Supports over 100 mainstream brands such as Cisco, Huawei, Dell, etc., and can customize different brand codes on both ends.
✅Factory 100% real machine testing: Refuse false compatibility! Each cable has passed the full speed test of a real switch, with zero packet loss and zero errors.
✅The first choice for cost reduction and efficiency improvement: the cost is only 20% of the original factory optical module combination, the power consumption is close to 0W, and the high-frequency data center PUE optimization artifact.
Yingda passive and active Twinax DAC cables provide a cost-effective, low-latency, and low-power solution for short-distance top-of-rack (ToR) interconnects in data centers. Supporting speeds from 10G SFP+, 25G SFP28 to 100G QSFP28 and 400G, each cable is 100% real-switch tested to ensure seamless compatibility with major brands.

The smaller the AWG number, the thicker the corresponding cable diameter, and the longer the transmission distance. Below are recommendations for commonly used transmission distances and their corresponding wire diameters:
✅When using Intel network cards, if choosing a 3-meter twinax SFP cable, a 26AWG thick cable is required; otherwise, unstable connections may occur. For lengths less than 3 meters, a 30AWG thin cable can be used.
✅When interconnecting with Cisco switches, a 5-meter length of 30AWG thin cable can be used. This is because Cisco incorporates sufficient compensation design in its switch chips, significantly reducing the cost.

With over 15 years of experience in active optical cable, passive direct attach cable, Yingda are proficient in creating high-quality fiber optic connectors and supporting products to meet various fiber access and fiber optic system upgrade solutions. Here are the reasons why we stand out:
Yingda offer a 100% compatibility guarantee.Yingda has 13 years of professional optical module research and development, and has 130 compatibility testing equipment and a complete compatibility database to meet diverse needs. It is compatible with different brands of equipment such as Minos, NVIDIA CX6 and CX7 network cards. If an error persists even after our customer service team has verified the specific model, we provide a 30-day hassle-free return and exchange policy, covering all shipping costs in both directions.
This design is made to safeguard your signal quality! For shorter distances (1 m), we utilize a thinner 30AWG gauge to make the cable more flexible and easier to route; for longer distances (3 m), we must upgrade to a thicker 24/26AWG copper core to counteract signal attenuation and ensure a 0% bit error rate.
In 99% of such cases, the cable itself is not defective; rather, the FEC (Forward Error Correction) modes on the devices at both ends do not match. You simply need to access the configuration interface of your switch or network card and manually synchronize the FEC settings on both ends (either both "On" or both "Off")—the connection will then light up instantly!
All Yingda DAC cables come with an extended 3-year warranty, ensuring complete peace of mind for your enterprise procurement needs.
DAC cable now is in hot selling, but with skilled workers and large productivity, our delivery is fast.
