Linkbasic's SFP-DQ1 is a high-performance Direct Attach Copper (DAC) cable engineered to provide up to 40 Gbps of bandwidth capacity. Featuring very low power consumption, this twinaxial cable offers an exceptionally cost-effective alternative to optical transceivers for establishing short-range 40G links between QSFP+ ports in high-speed uplink scenarios. Application Note: Ideal for top-of-rack (ToR) patching, connecting adjacent switches, routers, or network interface cards (NICs) within the same server cabinet.
