The JBX02317 1000BASE-ZX SFP transceiver is a high-performance optical module engineered for long-distance gigabit Ethernet transmission in professional network environments. This HPE JD063B compatible transceiver operates at 1550nm infrared wavelength, a wavelength specifically optimized for extended-reach single-mode fiber communications. **Key Performance Features:** With transmission capabilities reaching 80 kilometers over standard 9/125 single-mode fiber (SMF), this module eliminates the need for expensive specialty cabling while maintaining full 1000BASE-X Gigabit Ethernet speeds. The 1550nm wavelength minimizes signal attenuation and dispersion, making it ideal for campus interconnects, metropolitan area networks, and service provider deployments. **Technical Specifications & Compatibility:** The transceiver meets IEEE 802.3z standards and SFF-8472 specifications, ensuring interoperability with major networking equipment manufacturers. Its duplex LC/UPC fiber connectors provide secure, low-insertion-loss connections essential for maintaining signal integrity over long distances. Pre-qualified for HPE and H3C network switches and routers, this module drops directly into existing infrastructure as a JD063B replacement. **Safety & Compliance:** Comprehensive certifications including Class 1 laser safety, UL/FDA approval (21CFR 1040.10), and TUV validation guarantee safe operation in professional settings. Full RoHS and EU directive 2002/95/EC compliance ensures environmental responsibility and future regulatory alignment. **Operational Advantages:** The metal case construction provides electromagnetic shielding and thermal management, supporting reliable operation across 0-70°C temperature ranges. Custom brand programming is available for OEM applications. Backed by a 90-day limited warranty and shipped from convenient U.S. locations (Danville, CA or Beaufort, SC), this transceiver delivers enterprise-class reliability with accessible support and logistics.
