10G SFP+ Passive DAC Twinax Copper Cable (0.5-10m): 10G-PDAC-SFP

Our EDGEOPTIC 10G-PDAC-SFP is a multi-vendor compatible 10G SFP+ passive direct attach copper cable designed for high-performance 10 Gigabit Ethernet and Fiber Channel applications within data center and enterprise environments. The 10G-PDAC-SFP cable features point-to-point configuration with SFP+ connectors on both ends, delivering reliable high-bandwidth connectivity for short-reach interconnects between switches, servers, and storage systems.

The cable supports multi-rate operation from 1.0625 to 10.52 Gbps, accommodating various network protocols and legacy applications. For Ethernet deployments, the cable handles both Gigabit Ethernet at 1.25 Gbps and 10G Ethernet at 10.31 Gbps, providing backward compatibility for mixed-speed network environments. Fiber Channel support is comprehensive, including 1G FC at 1.0625 Gbps, 2G FC at 2.125 Gbps, 4G FC at 4.25 Gbps, 8G FC at 8.5 Gbps, and 10G FC at 10.52 Gbps, making the cable well-suited for storage area network connectivity across multiple generations of FC infrastructure.

As a passive DAC solution, the 10G-PDAC-SFP requires no external power and introduces zero latency to signal transmission, making it ideal for latency-sensitive trading floors, real-time analytics, and high-frequency applications. The cable construction utilizes high-quality twinax copper with AWG30 gauge for lengths from 0.5 to 3 meters and AWG24 gauge for lengths from 4 to 10 meters. This wire gauge optimization ensures optimal signal integrity across the extended distance range while maintaining excellent electrical characteristics for reliable data transmission.

The electrical interface conforms to SFP+ MSA and SFF-8431 specifications, ensuring broad compatibility with standard SFP+ host systems from multiple equipment vendors. Our 10G SFP+ DAC cables can be encoded for compatibility with over 80 different equipment brands including major networking and storage vendors. The cable incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality, providing real-time diagnostic data including module temperature and supply voltage through the MSA-compatible interface for proactive network monitoring.

The cable operates within a 0 to 70°C temperature range, suitable for controlled data center and enterprise environments. With an MTBF rating of 1,000,000 hours, the cable delivers long-term reliability for mission-critical infrastructure deployments.

Typical deployment scenarios include top-of-rack switch interconnects, server-to-switch connectivity, storage area network links, and blade server connections. The passive design eliminates power consumption concerns entirely and reduces overall system power budget compared to active copper or optical alternatives, contributing to greener data center operations.

Our 10G SFP+ passive DAC is CE/RoHS certified and compliant with product safety standards. Because our focus is providing top quality service, we perform comprehensive quality checks before delivery of our products. As a result, we conduct electrical parameter measurements, connector inspection tests, and SFP+ EEPROM memory data validation tests to ensure reliable operation in your network infrastructure.
