The JBX02290 1000BASE-ZX SFP transceiver represents a premium solution for organizations requiring extended-range Gigabit Ethernet connectivity. This optical module is engineered to deliver consistent 1Gbps performance across distances up to 40 kilometers when deployed with standard single-mode fiber infrastructure, making it ideal for campus networks, metropolitan area networks (MANs), and long-distance interconnections between data centers. **Key Technical Specifications:** Operating at 1550nm wavelength, this transceiver utilizes proven long-wavelength technology that minimizes signal degradation over extended fiber distances. The single-mode fiber design with 9/125 micron core ensures optimal signal fidelity and reduced chromatic dispersion. The duplex LC/UPC connector configuration provides a reliable, low-loss connection point compatible with standard network infrastructure. **Compatibility & Integration:** The JBX02290 is specifically designed as a compatible replacement for HPE part number JD062A and supports HPE and H3C networking equipment seamlessly. This compatibility extends the module's utility across enterprise environments already standardized on these platforms, eliminating the need for proprietary solutions. **Reliability & Compliance:** Constructed with a robust metal case and precision laser transmitter, this module meets stringent international safety and quality standards. Class 1 Laser certification, TUV approval, UL/FDA compliance under 21CFR 1040.10, and RoHS/ELV directive adherence ensure safe operation and environmental responsibility. The module qualifies to IEEE 802.3z standards and maintains performance across the full operating temperature range of 0-70°C. **Applications:** Ideal for long-haul network segments requiring reliable optical transmission, including inter-building connectivity, disaster recovery links, metropolitan network expansion, and high-availability system designs. The 40km range effectively bridges geographic distances that would otherwise require additional optical regeneration equipment. **Value Proposition:** Offer custom brand programming capabilities, comprehensive safety certifications, and a 90-day limited warranty. With free standard shipping on orders exceeding $99 and availability from multiple US fulfillment locations (Danville, CA and Beaufort, SC), this transceiver provides enterprise-class networking at competitive pricing.
