This 3-meter 10G SFP+ Direct Attach Copper (DAC) twinax cable is a passive copper interconnect designed for high-speed network environments. It supports 10Gbase-CU standards and operates at 10 Gbps data rates, making it suitable for connecting switches, routers, and servers within racks or adjacent equipment. The cable utilizes twinax construction with two balanced coaxial lines, which helps reduce signal interference and maintain stable transmission over the three-meter length. The connectors are built with durable metal housings and gold-plated contacts to ensure reliable electrical connectivity and repeated plugging cycles. This model is compatible with a wide range of networking hardware, including Cisco SFP-H10GB-CU3M interfaces, as well as equipment from Ubiquiti, Juniper, Mellanox, Mikrotik, Netgear, Supermicro, and many open-source switch platforms. The blue color sleeve aids in cable identification and organization in dense cabling environments. The construction of this DAC cable focuses on durability and consistent performance. The outer jacket is made from flexible yet rugged PVC material that resists abrasion and maintains bend radius requirements for standard rack installations.

Inside, the twinax conductors are individually shielded to minimize crosstalk and external electromagnetic interference, which is critical for maintaining 10G signal integrity over the three-meter passive link. The SFP+ connectors are latch-style with a robust pull-tab mechanism that allows easy insertion and removal without stressing the PCB or transceiver housing. Each unit undergoes functional testing before shipment to verify bit error rates and signal stability. The passive design means no external power or signal amplification is needed, reducing power consumption and heat generation compared to active optical cables or transceivers. This makes the cable an energy-efficient choice for high-density data centers. In terms of performance, this cable delivers low latency and consistent throughput for 10 Gigabit Ethernet applications. It supports SFP+ direct-attach connections without the need for additional media converters or power adapters, simplifying deployment in existing network infrastructures. The three-meter length is optimal for linking devices within the same rack or adjacent racks, and the flexibility of the cable allows for neat routing without excessive strain on ports. The cable is fully compliant with the SFF-8431 and SFF-8432 industry standards, ensuring interoperability with compliant SFP+ slots. Users can expect plug-and-play functionality, as the cable is recognized automatically by supported hardware. The passive copper medium also offers lower propagation delay compared to active cables, which can be beneficial for time-sensitive applications like financial trading or high-performance computing clusters. This cable is particularly well-suited for IT professionals and system administrators building or expanding 10G networks on a budget. It offers a practical alternative to optical transceivers while delivering similar performance at a fraction of the cost. The compatibility list covers major enterprise and prosumer switch brands, as well as open-source network operating systems, making it a versatile addition to any networking toolkit. The affordable pricing—available at $14.90—provides significant savings compared to OEM-branded DAC cables, without compromising on reliability or data integrity. For those requiring a clean, cost-effective cabling solution for short-range 10G links, this passive twinax cable delivers the necessary specifications and build quality to meet everyday networking demands.
