The JBX05240 7-meter Cisco QSFP+ to SFP+ direct attach copper breakout cable represents a premium connectivity solution for modern data centers and enterprise networks requiring high-speed, reliable signal transmission. Designed as a fully compatible alternative to Cisco's QSFP-4X10G-AC7M, this cable enables seamless integration into existing network infrastructure without additional configuration or compatibility concerns. Technical Specifications: This active breakout DAC cable supports 40GBASE-CR4 standards, delivering robust 40GB aggregate data rates with four independent 10GB channels. The 30AWG twinax copper construction ensures superior signal integrity and minimal attenuation across the 7-meter span. Each conductor is precisely engineered to meet IEEE 802.3ba specifications, guaranteeing consistent performance and reliability in demanding network environments. Key Features & Benefits: The cable features QSFP+ connectors on one end and four SFP+ connectors on the other, providing flexible deployment options. Its compact 12x12x7 dimension profile facilitates easy installation in tight rack configurations. The active breakout design eliminates passive splitter limitations, delivering full-speed performance without signal degradation. RoHS, TUV, and UL certifications confirm compliance with international safety and environmental standards. Ideal Applications: Perfect for data center interconnects, storage area networks (SANs), and enterprise backbone connectivity. Organizations upgrading from 10GB to 40GB infrastructure benefit from this cable's ability to transition existing SFP+ equipment gradually. The 7-meter length accommodates medium-distance connections within large facilities without requiring additional intermediary equipment. Performance & Reliability: Operating across 0-70°C temperature ranges ensures reliable performance in diverse environmental conditions. The 90-day limited warranty provides confidence in quality and durability. Custom brand programming is available for organizations requiring OEM-specific labeling. Value Proposition: Compare this solution to traditional passive DAC cables: active breakout technology ensures superior signal quality over longer distances, reducing the need for expensive active repeaters or regenerators. Free standard shipping on orders exceeding $99 makes this enterprise-grade connectivity solution economically accessible.
