The JBX02239 1000BASE-EZX SFP Transceiver represents premium optical networking technology engineered for long-distance gigabit communications. This extended-range transceiver enables 120-kilometer transmission over single-mode fiber, delivering exceptional performance for carrier-grade and enterprise network infrastructure. **Technical Excellence** This 1000BASE-EZX module operates at 1550nm wavelength, utilizing single-mode fiber (9/125 SMF) to achieve extended transmission distances without signal degradation. The duplex LC/UPC connector design ensures reliable connections and minimizes insertion loss, critical for maintaining signal integrity over extended distances. **Compatibility and Integration** Fully compatible with Extreme Networks AA1419071 equipment, the JBX02239 serves as a direct replacement for legacy infrastructure upgrades. The SFP form factor allows hot-swappable installation in compatible network equipment, minimizing downtime during deployment or maintenance. **Standards Compliance** Qualified to IEEE 802.3z specifications and SFF-8472 standards, this transceiver guarantees interoperability with certified network equipment. Class 1 laser safety certification and TUV/UL/FDA approvals ensure safe operation in demanding network environments. **Operational Specifications** Temperature range from -10 to 85°C accommodates outdoor and industrial installations. The metal case with integrated laser transmitter provides durability and EMI protection. RoHS/ELV compliance reflects our commitment to sustainable manufacturing practices. **Applications** Ideally suited for metropolitan area networks (MANs), campus interconnects, carrier networks, and disaster recovery site connectivity. The 120km reach eliminates the need for expensive regeneration equipment in medium-distance deployments. **Warranty and Support** Backed by a 90-day limited warranty and available from strategically located fulfillment centers. Free standard shipping on orders over $99 and custom brand programming options provide flexibility for specialized deployments.
