The JBX05870 1-Meter 100GBASE-CR4 QSFP28 Passive Direct Attach Copper Cable represents an excellent networking solution for organizations seeking reliable, cost-effective high-speed connectivity. Designed specifically for Cisco-compatible equipment, this passive DAC cable delivers 100 gigabits per second of throughput over a compact 1-meter distance, making it ideal for server-to-switch and switch-to-switch connections in modern data centers. Technical Excellence and Performance: Constructed with premium 30AWG twinax copper conductors, this cable provides superior signal integrity and minimal electromagnetic interference. The passive design requires no external power or cooling, reducing operational overhead and power consumption while maintaining peak performance. Qualified to IEEE 802.3bj specifications and QSFP28 Multi-Source Agreement (MSA) standards, this cable ensures compatibility and interoperability across diverse networking environments. Compliance and Certification: The JBX05870 meets stringent international standards including RoHS (EU Directive 2002/95/EC) and ELV compliance, ensuring environmental responsibility and safety. TUV and UL certifications guarantee reliability and durability in demanding data center environments. The 90-day limited warranty provides additional peace of mind for critical network infrastructure investments. Seamless Integration: This cable functions as a direct, plug-and-play replacement for Cisco OEM part numbers QSFP-100G-CU1M and MA-CBL-100G-1M, enabling quick upgrades or replacements without compatibility concerns. The standardized QSFP28 connectors ensure broad equipment compatibility while the 1-meter length provides optimal flexibility for typical rack-mounted configurations. Practical Applications: Perfect for data center operators, cloud service providers, and enterprise IT departments seeking to upgrade network infrastructure without excessive capital expenditure. The passive architecture excels in high-density deployments where heat dissipation and power consumption are critical considerations. The 1-meter length covers standard intra-rack and adjacent-rack distances efficiently. Operational Durability: With an operating temperature range of 0-70°C (32-158°F), this cable maintains performance across typical data center climate conditions. The durable plastic jacketing protects copper conductors from physical damage and environmental factors. Manufactured in Vietnam and China using quality control standards ensures consistent product reliability.
