The JBX01469 is a premium-grade 100GBASE-LR4 QSFP28 optical transceiver engineered for high-speed, long-distance data transmission in enterprise networks. As a direct replacement for Juniper QSFP-100G-LR4-ET modules, it provides seamless integration into existing infrastructure while delivering exceptional performance and reliability. **Technical Specifications:** This transceiver operates at 100 gigabits per second over single-mode fiber (SMF) with a 9/125 micron core, achieving reliable transmission distances up to 10 kilometers. The duplex LC/UPC connectors ensure secure, low-loss connections while maintaining optical signal integrity. Housed in a compact 5x4x2 inch metal case with integrated laser transmitter, the module is designed for high-density deployment in modern data center environments. **Performance & Standards Compliance:** Fully qualified to IEEE 802.3bm specifications and QSFP28 Multi-Source Agreement (MSA) standards, this module guarantees compatibility with Juniper switches and routers. The optical design utilizes advanced laser transmission technology classified as Class 1 laser-safe, certified by TUV and FDA (21CFR 1040.10). **Reliability & Environmental Performance:** Built to operate across an extended temperature range from -10°C to 85°C (-14°F to 185°F), this transceiver maintains peak performance in various installation environments. RoHS/ELV compliance ensures environmental responsibility without compromising performance. The 90-day limited warranty provides peace of mind for critical network deployments. **Application Areas:** Ideal for data center interconnects, metropolitan area networks (MANs), carrier-class backbone links, and campus network extensions. Perfect for organizations requiring high-capacity, long-distance optical connectivity without the expense of ultra-long-reach modules. **Shipping & Support:** Enjoy free standard shipping on orders over $99 from our distribution centers in California and South Carolina. Custom brand programming is available for enterprise customers requiring specialized configurations. This is a proven solution for network professionals seeking reliable, standards-compliant 100GB optical connectivity.
