S125-LP-DAC passive copper cable assemblies provide high-performance, cost-effective connectivity solutions for 1 Gbps Ethernet and 1 Gbps Fibre Channel applications. These cables enable hardware manufacturers to achieve high port density, flexible configuration and efficient port utilization while maintaining low costs and reduced power consumption.Designed to deliver reliable high-speed data transmission, these cable assemblies meet or exceed industry standards for Gigabit Ethernet and Fibre Channel in terms of performance and reliability. They are classified as passive copper cables because they do not contain signal conditioning circuitry, such as crosstalk or echo cancellation, within the SFP connectors. They are also commonly known as DAC (Direct Attach Cable) cables.S125-LP-DAC cable is a good alternative to link 1 Gbps SFP ports, with low-cost, low power consumption and low latency.
