The JBX01799 10GBASE-ER SFP+ transceiver represents an excellent solution for organizations requiring extended-range optical connectivity without the expense of proprietary vendor solutions. This module delivers 10 gigabit Ethernet performance with exceptional reach capabilities, supporting transmission distances up to 40 kilometers over single-mode fiber infrastructure. **Technical Excellence and Performance** Operating at the 1550nm wavelength, this transceiver utilizes proven infrared technology for superior signal propagation over long distances. The extended-range (ER) specification ensures reliable operation even in challenging network topologies where distance becomes a critical factor. The duplex LC/UPC connector design provides bidirectional communication with minimal signal loss, supporting full-duplex 10GB data rates for seamless network traffic management. **Compatibility and Integration** Designed as a drop-in replacement for Extreme Networks AA1403013-E6 transceivers, the JBX01799 simplifies equipment upgrades and network expansion projects. The SFP+ form factor offers maximum flexibility for installation in various network devices, supporting dense port configurations in modular switching platforms. Custom brand programming is available for organizations requiring OEM-specific configurations. **Safety, Compliance, and Reliability** This optical module meets stringent international standards including IEEE 802.3ae specifications and SFF-8431/SFF-8472 small form factor standards. Comprehensive safety certifications—Class 1 Laser, TUV, UL, and FDA 21CFR 1040.10—ensure safe operation in professional environments. Full RoHS and ELV compliance demonstrates commitment to environmental responsibility, aligning with EU directive 2002/95/EC requirements. **Application Scenarios** Ideal for metropolitan area networks connecting distant office locations, data center interconnects, and carrier-class network deployments. The 40km reach enables efficient network architecture without requiring expensive amplification equipment. Operating temperature range of 0-70°C accommodates both climate-controlled data centers and outdoor fiber distribution installations. **Service and Support** Offered with 90-day limited warranty, backed by free standard shipping on orders exceeding $99. Manufactured to exacting standards using quality materials and precision laser transmitter technology. Ships from strategically located U.S. facilities (Danville, CA and Beaufort, SC) for rapid delivery and local support.
