Siemon's Cisco Compatible SFPG High-Speed Direct-Attach Copper (DAC) passive cables offer an efficient cabling option to meet rack design requirements today and with future equipment upgrades. These forward compatible cables are designed for use with 10G SFP+ Cisco equipment without generating warning messages, and allow migration to 25G SFP28 equipment without the need to replace cabling.

Our DACs offer dual-rated CM/LSOH jackets for global compatibility and are available in lengths ranging from 0.5m to 5m with half meter options. The fully-shielded, passive assemblies combine twin-axial cable configuration with robust die-cast housings for enhanced support of high frequency data rates and are impedance matched to ensure interoperability and minimize EMI leakage. They are a cost-effective, low-power alternative to fiber-based solutions for short reach requirements supporting data transfer rates up to 25G, meeting or exceeding current network standards.
