The JBX01444 is a premium 100GBASE-LR1 QSFP28 optical transceiver engineered for demanding enterprise and data center network environments. Delivering blazing-fast 100GB data rates over single-mode fiber, this module extends network reach up to 10 kilometers—perfect for campus interconnects, metro networks, and enterprise backbone installations. **Key Technical Specifications:** This transceiver utilizes a 1310nm wavelength transmission over 9/125 single-mode fiber (SMF), ensuring optimal signal integrity and minimal attenuation. The Duplex LC/UPC fiber connectors provide industry-standard mechanical reliability with precision-polished optical interfaces. Housed in a rugged metal case with integrated laser transmitter technology, the module maintains strict Class 1 laser safety compliance and operates across extended temperature ranges (0°C to 70°C / 32°F to 158°F). **Compatibility & Standards:** Designed as a direct replacement for Palo Alto Networks PAN-QSFP28-LR1-100G-SL modules, this transceiver integrates seamlessly into existing network infrastructure. Full compliance with IEEE 802.3bm and QSFP28 MSA standards ensures interoperability and future-proof performance. **Regulatory & Quality Assurance:** The JBX01444 carries comprehensive safety certifications including UL/FDA (21CFR 1040.10), TUV, and RoHS/ELV compliance, meeting stringent EU Directive 2002/95/EC requirements. Custom brand programming is available for organizations requiring OEM integration. **Practical Applications:** Ideal for data center operators, network integrators, and IT professionals upgrading to 100G infrastructure. Perfect for inter-switch connections, router-to-router links, and long-distance metropolitan area network deployments. The reliable 10km reach eliminates the need for intermediate amplification while maintaining pristine signal quality. **Service & Support:** Backed by a 90-day limited warranty and available with free standard shipping on orders exceeding $99. Ships promptly from US locations (Danville, CA and Beaufort, SC), ensuring quick deployment and minimal network downtime.
