The JBX02224 1000BASE-EX SFP transceiver represents enterprise-class optical networking technology optimized for extended metropolitan area network (MAN) and wide area network (WAN) deployments. This single-mode fiber optic module transmits data at 1 Gigabit per second across distances up to 40 kilometers, significantly extending network reach compared to standard short-range SFP modules. **Key Technical Features:** Operating at 1310nm wavelength, this transceiver uses industry-standard 9/125 micron single-mode fiber cores compatible with standard SMF installations. The duplex LC/UPC connector configuration provides reliable, low-insertion-loss connections with excellent return loss characteristics. The metal housing with integrated laser transmitter ensures electromagnetic shielding and optimal thermal management across the operating temperature range of -14 to 185°F (-10 to 85°C). **Performance & Compatibility:** Qualified to IEEE 802.3z specifications and SFF-8472 standards, this module delivers predictable performance metrics. It directly replaces Extreme Networks OEM part numbers AA1419050 and AA1419050-E6, ensuring plug-and-play compatibility with existing infrastructure without firmware or configuration changes. **Safety & Compliance:** The transceiver holds multiple regulatory certifications: Class 1 Laser classification, TUV approval, UL/FDA compliance per 21CFR 1040.10, and full RoHS/ELV directive adherence (EU 2002/95/EC). These certifications guarantee safe operation in commercial and industrial network environments. **Ideal Applications:** - Campus backbone interconnects - Data center metro connections - Carrier-grade network extensions - Financial institution networks requiring extended reach - University and corporate WAN deployments **Warranty & Support:** Backed by a 90-day limited warranty with free standard shipping on orders exceeding $99. Ships from strategically located warehouses in Danville, CA and Beaufort, SC, ensuring rapid delivery. Custom brand programming available for white-label and OEM requirements.
