The JBX05495 5-meter Brocade Compatible 40GBASE-CR4 QSFP+ Active Direct Attach Copper Cable represents a cost-effective, high-performance solution for modern data center networking infrastructure. As enterprises continue to scale their network capabilities, this premium active DAC cable delivers the reliability and speed required for mission-critical applications. **Technical Specifications:** This cable features a robust 30AWG twinax copper construction encased in protective plastic jacketing, providing durability and consistent performance in demanding environments. The active DAC technology enables signal conditioning that compensates for cable loss, ensuring pristine data integrity across the full 5-meter span. With QSFP+ connectors on both ends, it seamlessly integrates with Brocade switches and other standards-compliant networking equipment. **Standards Compliance & Certification:** Qualified to IEEE 802.3ba specifications and SFF-8436 standards, this cable meets the stringent requirements of enterprise-grade networking. RoHS, TUV, and UL certifications ensure compliance with environmental and safety regulations, while the EU directive 2002/95/EC (RoHS) compliance demonstrates commitment to sustainable manufacturing practices. **Superior Performance Advantages:** Unlike passive DAC cables, the active architecture of this cable provides enhanced signal integrity and allows for extended reach without performance degradation. This makes it ideal for larger rack configurations and complex network topologies where cable runs might exceed passive cable limitations. The 40GB/s data rate supports demanding applications including virtual machine migration, backup operations, and high-frequency trading platforms. **Compatibility & Integration:** Designed as a direct replacement for OEM part number 40G-QSFP-QSFP-C-0501, this cable integrates seamlessly into existing Brocade environments. Its broad compatibility with standards-based QSFP+ equipment makes it suitable for heterogeneous network deployments. **Operational Reliability:** With an operating temperature range of 0-70°C (32-158°F), this cable performs reliably across diverse data center environments, from chilled server rooms to moderately warm equipment closets. The 90-day limited warranty provides peace of mind, while custom branding options are available for organizations requiring asset identification. **Why Choose Active DAC Technology:** Active direct attach copper cables eliminate the cost and complexity of optical transceivers while delivering comparable performance for medium-range connections. Perfect for east-west traffic in modern data center architectures, this cable reduces total cost of ownership while maintaining the high-speed connectivity your infrastructure demands.
