The JBX05727 2.5m 100GBASE-CR4 QSFP28 passive direct attach copper cable represents a cost-effective, high-performance solution for enterprise data center networking. Engineered specifically for Extreme Networks compatibility, this cable delivers the full 100GB throughput required for next-generation network infrastructures without compromise. Designed for short-reach, high-density deployments, the passive DAC architecture eliminates the need for active signal conditioning, resulting in lower power consumption, reduced heat generation, and decreased operational costs compared to active solutions. The 28AWG twinax copper construction provides excellent signal integrity and reliable transmission with minimal latency, making it ideal for latency-sensitive applications and high-frequency trading environments. This cable meets rigorous industry standards including IEEE 802.3bj specifications, QSFP28 MSA (Multi-Source Agreement), and SFF-8665 form factor requirements. The 2.5-meter length strikes an optimal balance between flexibility and performance, suitable for standard rack-to-rack connectivity, top-of-rack (ToR) switch connections, and modular network configurations. Compliance and certification are paramount in enterprise deployments. The JBX05727 carries RoHS (Restriction of Hazardous Substances) certification, TUV approval, and UL certification, ensuring compliance with EU Directive 2002/95/EC and other regulatory frameworks. This makes it suitable for regulated industries including finance, healthcare, and government sectors. Operating across a 0-70°C temperature range, this cable maintains performance consistency whether deployed in climate-controlled data centers or more variable environments. The plastic jacketing provides abrasion resistance and durability in high-traffic cable management areas. The cable directly replaces multiple OEM part numbers including Extreme Networks 100G-DACP-QSFP2Z5M, making upgrades and refreshes straightforward without architectural changes. Perfect for network expansion, equipment upgrades, or disaster recovery initiatives. Each cable ships with a 90-day limited warranty, backed by expert technical support. Qualifying orders receive free standard shipping from either Danville, CA or Beaufort, SC, ensuring rapid deployment. Custom brand programming is available for enterprise procurement requirements.
