The JBX02204 1000BASE-BX40-U SFP transceiver represents a sophisticated solution for organizations requiring extended-reach optical networking capabilities. This module delivers 1 Gigabit per second (1GbE) performance over single-mode fiber (SMF) at distances up to 40 kilometers, enabling cost-effective long-distance network deployments without requiring expensive repeaters or amplifiers. Technical Excellence and Compatibility: This transceiver achieves extended-reach transmission through advanced bidirectional (BiDi) technology, utilizing separate wavelengths for transmit (1310nm) and receive (1550nm) functions over a single fiber strand. The simplex LC/UPC connector ensures secure, low-loss connections with standard fiber infrastructure. Full qualification to SFF-8472 specifications and IEEE 802.3ah standards guarantees interoperability across professional networking environments. Native Juniper compatibility, with direct replacement capability for part number SFP-1GT13R15BX40-I, ensures seamless integration into existing deployments. Industrial-Grade Construction: The metal-encased design with integrated laser transmitter provides exceptional durability and thermal management. The transceiver operates reliably across demanding industrial temperature ranges (-40°C to 85°C / -40°F to 185°F), accommodating outdoor installations, data center environments, and climate-controlled facilities alike. Built-in safety certifications—Class 1 Laser, TÜV, UL, and FDA 21CFR 1040.10 compliance—ensure worker safety and regulatory adherence in all deployment scenarios. Compliance and Quality Assurance: Designed with RoHS/ELV compliance per EU Directive 2002/95/EC, this transceiver meets strict environmental and hazardous substance restrictions, making it suitable for global deployment. The 90-day limited warranty provides peace of mind, while free standard shipping on orders exceeding $99 enhances value delivery. Ideal Applications: Perfect for campus interconnects, metro area networks (MANs), telecommunications infrastructure, and remote facility connectivity. Organizations benefit from reduced capital expenditure compared to long-haul equipment while maintaining carrier-class reliability and performance standards. Custom Configuration Available: Custom brand programming options allow seamless integration into private-label product portfolios and enterprise network architectures, providing flexibility for system integrators and managed service providers.
