The JBX01890 10GBASE-ZR SFP+ Transceiver represents a premium solution for organizations requiring high-speed, long-distance optical networking. This SFP+ module combines advanced 1550nm laser technology with robust construction to deliver consistent 10GB performance across distances up to 120 kilometers over single-mode fiber infrastructure. **Key Technical Features:** Operating at the extended 1550nm wavelength, this transceiver minimizes signal attenuation and enables unprecedented transmission distances without requiring expensive amplification equipment. The duplex LC/UPC fiber connectors provide secure, low-loss connections with minimal return loss. The compact SFP+ form factor (5x4x2mm) allows for maximum port density in network equipment while maintaining thermal efficiency. **Performance & Reliability:** Qualified to IEEE 802.3ae specifications, the module ensures interoperability across standard-compliant equipment. It operates reliably across industrial temperature ranges (0-70°C / 32-158°F), supporting both data centers and outdoor telecommunications infrastructure. The metal case with integrated laser transmitter provides superior EMI shielding and optical performance. **Compliance & Certifications:** Fully RoHS/ELV compliant per EU Directive 2002/95/EC, this transceiver meets stringent environmental and safety standards. Class 1 laser certification, FDA compliance (21CFR 1040.10), and TUV/UL validation ensure safe operation in mission-critical environments. SFF-8431 and SFF-8472 compatibility guarantees diagnostic capabilities and seamless integration. **Ideal Applications:** - Service provider metro and long-haul networks - Campus interconnects exceeding 100km distances - Data center replication and backup links - Enterprise WAN optimization - Telecommunications infrastructure **Additional Benefits:** - Cisco SFP-10G-ZR120 direct compatibility - Custom brand programming available for OEM requirements - 90-day limited warranty - Free standard shipping on orders over $99 - Ships from US locations (Danville, CA and Beaufort, SC) Whether upgrading existing infrastructure or deploying new long-distance connectivity, the JBX01890 delivers enterprise-grade performance with exceptional value.
