The JBX01586 is a premium-grade 10GBASE-T SFP+ transceiver module engineered to deliver exceptional performance in demanding network environments. Designed as a cost-effective alternative to fiber optics, this copper-based transceiver achieves 10 Gigabit Ethernet speeds with impressive 80-meter reach capabilities over standard CAT6A twisted-pair cabling. **Technical Specifications:** This module meets IEEE 802.3an standards and SFF-8472 specifications, ensuring universal compatibility across major networking platforms. The compact form factor (5.0 x 4.0 x 2.0 inches) fits standard SFP+ slots, enabling easy deployment in existing infrastructure without requiring chassis modifications. Operating temperature range of 0-70°C (32-158°F) supports both air-conditioned data centers and field deployments. **Compatibility & Integration:** Fully compatible with Cisco systems, this transceiver directly replaces OEM part numbers SFP-10G-T80, MA-SFP-10GB-T80, and SFP-10G-T80-S. The RJ45 connector interface eliminates the need for specialty fiber tools and training, reducing deployment costs and complexity. Custom brand programming is available for organizations requiring white-label or OEM modifications. **Build Quality & Compliance:** Robust metal case construction with professional-grade PCB design ensures long-term reliability and durability in 24/7 operational environments. Comprehensive compliance certifications including RoHS (EU directive 2002/95/EC) and ELV standards demonstrate adherence to international environmental and safety regulations. TUV and UL certifications provide additional assurance of quality and safety compliance. **Value & Support:** Every unit includes a 90-day limited warranty covering manufacturing defects. Free standard shipping on orders exceeding $99 makes this transceiver accessible to organizations of all sizes. Ships from strategically located fulfillment centers in Danville, CA and Beaufort, SC for rapid delivery to customers nationwide. **Ideal Applications:** Perfect for campus networking, data center interconnects, server consolidation projects, and enterprise network expansions where copper connectivity is preferred over fiber. The 80-meter range accommodates building-to-building connections and large-scale facility networking requirements.
