The JBX02187 1000BASE-BX40-U SFP Transceiver represents premium-grade optical interconnect technology for enterprise-class network infrastructure. This extended-reach bidirectional (BiDi) module delivers 1 Gigabit Ethernet performance across singlemode fiber networks spanning up to 40 kilometers—ideal for metropolitan area networks, campus interconnects, and long-distance data transmission requirements. Key Technical Specifications: This transceiver operates at 1310nm for transmission and 1490nm for reception (or vice versa), enabling full-duplex communication over a single fiber strand. The 9/125 micrometer singlemode fiber core provides optimal signal propagation for extended distances while minimizing chromatic dispersion. The simplex LC/UPC connector offers superior optical coupling efficiency and durability through multiple mating cycles. Performance and Reliability: Qualified to SFF-8472 extended-reach BiDi specifications, the JBX02187 exceeds standard IEEE 802.3ah requirements. The metal case construction with integrated laser transmitter delivers exceptional EMI shielding and thermal stability. Operating temperature range of -40 to 85°C accommodates deployment in various climates and facilities, from temperature-controlled data centers to outdoor cabinet installations. Compatibility and Integration: Engineered as a direct replacement for Brocade E1MG-BXU40-T modules, this transceiver integrates seamlessly into existing switch and router infrastructure without requiring firmware modifications or reconfiguration. The standardized SFP form factor ensures compatibility with all SFP-equipped network equipment. Compliance and Safety: Full RoHS and EU directive 2002/95/EC compliance reflects our commitment to environmental responsibility. Comprehensive safety certifications including Class 1 Laser designation, TUV, UL/FDA 21CFR 1040.10, and LN #50 7/2001 ensure operator safety and regulatory compliance across global markets. Value Proposition: With free standard shipping on orders exceeding $99 and 90-day limited warranty coverage, the JBX02187 delivers exceptional value for network infrastructure investments. Custom brand programming is available for OEM partnerships and white-label applications. Ideal Applications: Deploy the JBX02187 in long-distance interconnects, redundant network paths, campus area networks, and metropolitan Ethernet services where extended reach and reliability are paramount.
