The JBX02291 1000BASE-ZX SFP Transceiver represents a sophisticated solution for organizations requiring high-performance, long-distance optical networking capabilities. This advanced module is specifically designed to meet the demanding requirements of service providers, enterprise networks, and telecommunications infrastructure requiring reliable gigabit-speed connectivity across extended distances. **Extended Range Performance** With a maximum transmission distance of 70 kilometers over single-mode fiber, the JBX02291 significantly extends network reach without requiring intermediate amplification or regeneration equipment. The 1550nm wavelength operates in the telecommunications band, optimizing signal propagation through standard SMF infrastructure while minimizing chromatic and polarization-mode dispersion. **Superior Compatibility** As a verified replacement for Brocade E1MG-LHA and E1MG-LHA-OM modules, this transceiver integrates seamlessly into existing Brocade switching and routing environments. The SFP form factor ensures hot-swappable installation, enabling simple upgrades without system downtime or complex reconfiguration. **Enterprise-Grade Construction** The metal case with integrated laser transmitter provides electromagnetic shielding and thermal management for optimal performance in diverse deployment environments. The 9/125 micron single-mode fiber core supports standard telecommunications-grade SMF cabling commonly found in modern network installations. **Comprehensive Compliance** This transceiver meets rigorous international standards including IEEE 802.3z specifications, EU RoHS directive 2002/95/EC, and multiple safety certifications (Class 1 Laser, TUV, UL/FDA 21CFR 1040.10). These certifications ensure safe operation in any environment and compliance with global environmental regulations. **Technical Specifications** Operating temperature range of -10 to 85°C accommodates both indoor and outdoor installations. Duplex LC/UPC connectors provide low-loss, angled physical contact termination. The module supports full-duplex communication at 1 Gigabit per second with stability across extended temperature ranges. **Value and Support** Included custom brand programming capabilities allow network administrators to apply organizational branding or labeling preferences. The 90-day limited warranty provides confidence in product reliability, while free standard shipping on orders exceeding $99 offers significant cost savings for bulk deployments. Ships from multiple U.S. locations (Danville, CA and Beaufort, SC) for optimized delivery times.
