QSFP+ DAC cable consists of two QSFP fiber transceiver modules that are directly connected to the DAC cable. 40G QSFP+ direct attach copper cables are designed for 40 Gigabit Ethernet applications, using in the short distance connections within or between adjacent racks in the data center. 40G DAC cables provide a QSFP+ to QSFP+ copper direct attach solution. QSFP+ direct attach copper cables provide a cost-effective solution for short-haul interconnect applications in data centers. DAC cables are easy to install, fast, and cost-effective for short distance transmission.
The direct attach copper cable is commonly using in the short distance of data transmission, so the length of the DAC cable are usually 1m/2m/3m/5m/7m. For the short distance, 40G DAC cables are widely used for establishing connections within the same rack or between adjacent racks in data centers. This intra-rack and inter-rack connectivity is essential for linking networking equipment, servers, and storage devices, creating a cohesive and high-performance infrastructure within the data center environment.
DAC cables is to provide cost-effective networking solutions for short distance connections. As an alternative to optical transceivers and fiber optic cabling, direct attach copper cable offer comparable performance at a lower cost, making them an economical choice for high-speed data transmission in limited network space. The internal material of the high-speed DAC cables is copper core, which is both energy efficient and environmentally friendly as it provides natural heat dissipation. The active optic cables typically consume around 440mW, but the direct attached copper cable do not require a power source, it could save on the on electricity costs.
If you are looking for a potential DAC cable solution to solve network latency, utility costs or density issues, let UnitekFiber help. We are committed to providing high-quality DAC cable that undergo stringent testing procedures. Our meticulous approach encompasses every step, from careful material selection to rigorous performance evaluations. By adhering to these rigorous standards, our DAC cable are designed to deliver reliable and high-performance data transmission in even the most demanding network environments. With the incorporation of top-quality components and our unwavering commitment to stringent testing processes, the DAC cable has become the trusted choice for network professionals who seek unparalleled quality and performance.
DAC cables are made from shielded Twinax copper coaxial and are factory equipped with modules on either end connected to fixed ports. The modules cannot be removed from the cable. Therefore, all DAC cables are produced at a fixed length.
Direct Attached Cables, or DACs, are copper cable assemblies made from twinax cable, terminated with transceiver housings on each end. DACs are available in passive or for active variants. Passive DACs are typically 7m in length or shorter and use less than 0.15W of power.
UnitekFiber's DAC cables includes passive direct-attach cables with speeds ranging from 10 Gbps to 400 Gbps, typically used for short-distance connections in enterprise and data centers or network equipment.
Direct Attach over Copper (DAC) cables have a minimum bend radius of typically 4x the diameter of the cable (approximately a 1" bend radius).
Before shipping, we have professional QC,and we will test the item strictly.
This product do a well work on the data center, absolutely save the space, save the installation time and could be manage the cable better than before. Highly recommended.
