The JBX02163 1000BASE-BX40-D SFP Transceiver represents a premium solution for organizations requiring cost-effective, long-distance optical connectivity. Engineered specifically for extended-reach networks, this simplex single-mode fiber (SMF) transceiver delivers 1 Gigabit per second (1000BASE-BX) performance across distances up to 40 kilometers—significantly outperforming standard short-reach alternatives. Key Technical Specifications: This optical transceiver features a 9/125 micron single-mode fiber core with simplex LC/UPC connectors, providing reliable, non-reflective connections. Operating on 1490/1310nm wavelengths, it enables bidirectional communication beyond standard IEEE 802.3ah specifications. The compact form factor (5x4x2 inches) fits seamlessly into standard SFP module slots, while the metal case with integrated laser transmitter ensures durability and thermal management. Compliance & Certifications: Fully RoHS/ELV compliant and qualified to SFF-8472 specifications, the JBX02163 meets stringent industry standards. Safety certifications include Class 1 Laser compliance, TUV, UL/FDA, and 21CFR 1040.10 designation, making it suitable for regulated environments. Compatibility & Applications: Designed as a direct replacement for Arista SFP-1G-BXD40 modules, this transceiver integrates seamlessly into existing Arista-based networks. Ideal applications include: - Metropolitan area networks (MANs) requiring 40km links - Campus network interconnects over extended distances - Telecommunications infrastructure deployments - Data center to remote office connectivity - Emergency services and critical infrastructure networks Operational Reliability: With a 90-day limited warranty and operating temperature range of 0-70°C (32-158°F), the JBX02163 performs reliably across demanding environments. Custom brand programming is available for OEM and integration partners. Value Proposition: Offering enterprise-grade performance at competitive pricing with free standard shipping on orders exceeding $99, the JBX02163 delivers exceptional value for long-distance optical network deployments.
