The JBX01902 10GBASE-ZR SFP+ Transceiver Module represents cutting-edge optical networking technology designed for organizations requiring extended-range, high-speed connectivity. As a purpose-built solution for long-distance data transmission, this module delivers exceptional performance in demanding networking environments. **Technical Specifications:** Operating at 1550nm wavelength, the JBX01902 achieves transmission distances up to 80 kilometers over standard singlemode fiber (9/125µm core). This extended reach makes it particularly valuable for campus interconnects, metropolitan networks, and disaster recovery configurations where standard short-reach transceivers fall short. The module supports full-duplex 10 Gigabit Ethernet transmission in compliance with IEEE 802.3ae specifications and SFF industry standards (SFF-8431, SFF-8472). **Compatibility and Integration:** This transceiver is engineered for seamless integration with Extreme Networks switching infrastructure. It directly replaces the Extreme Networks 10G-SFP-ZR module and is compatible with equivalent OEM part numbers. The hot-swappable SFP+ form factor enables easy installation and field replacement without requiring system shutdown or extensive configuration changes. **Connector and Physical Design:** Equipped with Duplex LC/UPC connectors, the module ensures optimal light coupling and minimal signal loss. The precise LC/UPC interface geometry provides excellent return loss characteristics critical for 10G applications. The compact 5x4x2 inch metal case design incorporates advanced laser transmission components while maintaining thermal stability across the full operating temperature range of 0-70°C (32-158°F). **Safety and Compliance:** This module exceeds industry safety requirements with Class 1 Laser certification, TUV validation, UL approval, and FDA 21CFR 1040.10 compliance. It meets RoHS and ELV directives for environmental sustainability. Manufactured in Vietnam and China using quality-assured processes, the transceiver carries a 90-day limited warranty. **Applications and Use Cases:** Ideal for: Long-distance data center interconnects, WAN links between office locations, disaster recovery replication over metropolitan distances, carrier-grade network infrastructure, and backbone connectivity requiring extended reach without regeneration. **Custom Programming Available:** This product supports custom brand programming, allowing organizations to standardize optical components across their infrastructure while maintaining compatibility requirements.
