The JBX02241 1000BASE-EZX SFP Transceiver represents a premium solution for long-distance optical networking applications. Specifically designed as a drop-in replacement for Extreme Networks MGBIC-LC07 modules, this transceiver eliminates compatibility concerns while delivering superior performance and reliability. **Technical Specifications:** Operating at 1550nm wavelength, the JBX02241 achieves exceptional transmission distances of 120km over 9/125 single-mode fiber, making it ideal for metropolitan area networks (MANs) and wide area network (WAN) connections. The transceiver supports full-duplex communication through dual fiber strands with LC/UPC connectors, ensuring minimal signal reflection and optimal performance. With a 1GB data rate, it provides sufficient bandwidth for contemporary enterprise applications while maintaining backward compatibility with legacy 1Gbps infrastructure. **Build Quality & Durability:** Constructed with a precision metal case and integrated laser transmitter assembly, the JBX02241 withstands demanding data center and outdoor deployment conditions. The duplex LC/UPC fiber interface provides excellent mechanical stability and repeatedly reliable connections. Operating across the 0-70°C temperature range accommodates both indoor facilities and outdoor cabinet installations. **Compliance & Safety:** This module meets stringent international standards including IEEE 802.3z and SFF-8472 specifications. It carries comprehensive safety certifications from TUV, UL, and FDA (21CFR 1040.10), plus Class 1 Laser safety designation. Full RoHS/ELV compliance ensures environmental responsibility and reduces hazardous material content. **Compatibility & Integration:** As a certified Extreme Networks MGBIC-LC07 equivalent, the JBX02241 drops directly into existing Extreme Networks switches and optical transport equipment without requiring firmware updates or reconfiguration. Custom brand programming is available for OEM integration needs. **Shipping & Support:** Shipped from US locations with free standard shipping on orders exceeding $99, backed by a 90-day limited warranty covering manufacturing defects. Manufactured in Vietnam and China using rigorous quality controls. **Applications:** Ideal for campus network extensions, metropolitan fiber links, redundant WAN connections, and carrier-class optical backbone deployments requiring long-distance single-mode transmission.
