QNAP QSFP DAC Cable

The QNAP CAB-NIC40G30M-QSFP QSFP DAC cable is a high-performance direct-attach copper cable designed for reliable 40-gigabit Ethernet connections between compatible network devices. This 30-meter cable features QSFP+ connectors on both ends and offers a cost-effective alternative to optical transceivers for short to medium distances in data centers and enterprise networks. Constructed with high-quality copper conductors and robust shielding, this passive DAC cable ensures stable signal transmission with minimal latency while maintaining signal integrity across the entire cable length. The cable supports data transfer rates of up to 40 Gbit/s and is backward compatible with 10-gigabit Ethernet applications when used with appropriate networking equipment. With a durable outer jacket and connector-side strain relief, this cable is designed for long-term reliability in demanding server room and data center installations. The QSFP DAC cable requires no external power supply and generates minimal heat compared to active optical solutions, making it an energy-efficient choice for high-density network deployments. Compatible with QNAP network devices and other QSFP+-capable devices from various manufacturers, this direct-attach cable simplifies network infrastructure and delivers consistent performance for storage area networks, server clusters, and high-speed computing applications. The cable maintains optimal performance within standard operating temperatures of 0 to 70 degrees Celsius and features a flexible design that allows for various installation configurations without compromising signal quality.
