The JBX05965 2-meter 200GBASE-CR4 QSFP56 Direct Attach Copper Cable represents a premium interconnect solution for modern high-speed networking infrastructures. Engineered to replace Cisco's proprietary QSFP-200-CU2M, this cable delivers identical performance at a competitive price point without compromising quality or reliability. **Technical Specifications & Performance** This passive DAC cable supports 200GB data rates compliant with IEEE 802.3cd specifications and QSFP56 MSA standards. The 26AWG twinax copper conductors minimize signal degradation while the plastic jacketing provides mechanical protection in rack environments. Operating temperature range of 0-70°C ensures stable performance in both cooled data centers and standard server rooms. **Design & Construction** The 2-meter length strikes an optimal balance between reach and signal integrity, ideal for spine-to-leaf or rack-to-rack connections. Precision-molded QSFP56 connectors ensure consistent insertion and reliable mating cycles. The compact 12x12x2 dimension profile minimizes footprint in densely populated switch ports. **Compliance & Safety** Fully RoHS and ELV compliant per EU directive 2002/95/EC, this cable meets stringent environmental standards. UL and TÜV certifications confirm adherence to electrical safety requirements, essential for enterprise deployments requiring regulatory documentation. **Cisco Compatibility** Direct compatibility with Cisco networking platforms eliminates integration concerns. This cable works seamlessly with Cisco switches and routers supporting 200GBASE-CR4 connectivity, reducing procurement complexity and deployment time. **Value & Warranty** Including a 90-day limited warranty, the JBX05965 provides peace-of-mind protection. Free standard shipping on orders exceeding $99 makes this solution accessible for budget-conscious IT teams. Custom brand programming is available for enterprises requiring proprietary labeling. **Applications** Ideal for data center architectures, high-performance computing clusters, and enterprise campus networks requiring high-bandwidth low-latency interconnects. Perfect for organizations standardizing on passive copper solutions to reduce power consumption and heat generation.
