The JBX01792 10GBASE-ER SFP+ Transceiver represents a premium solution for organizations requiring reliable, long-distance optical connectivity. This extended-range (ER) module is specifically designed to transmit 10GB signals across distances up to 40 kilometers using standard single-mode fiber with 9/125µm core, making it ideal for campus interconnects, metropolitan area networks, and carrier-grade deployments. **Key Technical Specifications:** Operating at 1550nm wavelength, this transceiver achieves exceptional performance across SMF infrastructure while maintaining signal integrity. The duplex LC/UPC connectors ensure secure, low-loss connections with minimal back-reflection. Compliant with IEEE 802.3ae and SFF standards (SFF-8431, SFF-8472), it guarantees interoperability across vendor ecosystems. The module operates reliably across 0-70°C temperature ranges, suitable for both climate-controlled datacenters and outdoor environments. **Performance & Reliability:** With dimensions of 5x4x2 inches and a metal case construction, this transceiver withstands rigorous deployment conditions. The integrated laser transmitter ensures optimal optical output while maintaining Class 1 Laser safety certification. RoHS and ELV compliance demonstrates commitment to environmental sustainability without compromising performance. **Compatibility & Cost Efficiency:** Direct compatibility with Dell systems (replacing OEM part numbers 407-BBEH and 407-BBOV) simplifies deployment while reducing procurement costs. Custom brand programming capabilities enable seamless integration into existing network management systems. This flexibility makes the JBX01792 an excellent choice for migration scenarios and multi-vendor environments. **Enterprise-Grade Support:** Every unit includes comprehensive safety certifications (UL/FDA 21CFR 1040.10, TUV certification) and manufacturing quality documentation. The 90-day limited warranty covers defects, while free standard shipping on orders over $99 adds value to bulk purchases. Whether upgrading existing infrastructure or deploying new optical networks, this transceiver delivers professional-grade reliability at competitive pricing.
