The JBX01235 40GBASE-LR4 QSFP+ transceiver represents a cost-effective solution for organizations requiring high-capacity, long-distance fiber optic connectivity. This optical module is engineered to meet the demanding requirements of modern data centers, telecommunications infrastructure, and enterprise networks. ## Technical Specifications This transceiver operates at 40 gigabits per second using the 40GBASE-LR4 standard, transmitting data over single-mode fiber (SMF) with a 9/125 micron core. The 10-kilometer reach makes it suitable for campus networks, metropolitan area networks (MANs), and wide-area network (WAN) applications where longer transmission distances are required without intermediate repeaters. ## Physical Design & Connectivity The compact QSFP+ form factor measures 5.0" x 4.0" x 2.0", fitting standard network equipment slots. Duplex LC/UPC connectors ensure secure, low-loss connections with professional-grade reliability. The metal case housing protects the internal laser transmitter while maintaining optimal thermal management across the 0-70°C operating temperature range. ## Compatibility & Integration Fullly compatible with Fortinet FG-TRAN-QSFP+LR and FN-TRAN-QSFP+LR equipment, this module serves as a drop-in replacement for existing installations. Designed to work seamlessly with IEEE 802.3ba and SFF-8436 standards, ensuring interoperability with major network equipment manufacturers. ## Compliance & Safety This transceiver meets stringent international safety and environmental standards, including RoHS/ELV compliance, Class 1 laser certification, and FDA 21CFR 1040.10 compliance. TUV and UL certifications validate safety and performance. Manufactured in Vietnam and China using quality-controlled processes. ## Custom Solutions Custom brand programming is available for organizations requiring OEM-specific configurations, allowing seamless integration into proprietary network management systems. ## Warranty & Support Each unit includes a 90-day limited warranty. With free standard shipping on orders exceeding $99 and convenient distribution from Danville, CA and Beaufort, SC locations, rapid deployment is guaranteed.
