The JBX02186 1000BASE-BX40-U SFP transceiver represents a premium solution for organizations requiring extended-reach optical connectivity across their network infrastructure. Designed to replace OEM part number Brocade E1MG-BXU40, this module delivers exceptional performance while maintaining full backward compatibility with existing Brocade equipment deployments. Technical Excellence: This simplex LC/UPC optical transceiver operates at 1Gbps over distances up to 40km, making it ideal for metropolitan area networks (MANs) and long-haul connections. The module utilizes advanced bidirectional (BiDi) technology, transmitting at 1310nm and receiving at 1490nm (or vice versa), enabling efficient single-fiber operation that reduces cabling requirements and installation costs. Robust Construction: Built with a metal case housing and integrated laser transmitter, the JBX02186 provides durability in challenging environments. The 9/125μm single-mode fiber core ensures low-loss transmission and minimal signal degradation over extended distances. With operating temperatures ranging from -10°C to 85°C, this transceiver maintains reliable performance in diverse climate conditions. Compliance & Safety: Fully certified to SFF-8472 extended-reach specifications, the module exceeds IEEE 802.3ah standards for gigabit Ethernet. Class 1 Laser certification, combined with RoHS/ELV directive compliance, ensures regulatory adherence and workplace safety. TUV, UL, and FDA certifications (21CFR 1040.10) validate its suitability for mission-critical applications. Applications & Benefits: Ideals for data center interconnects, campus network expansions, and service provider backbone deployments. The simplex configuration with extended range eliminates the need for multiple fiber strands while delivering gigabit performance. Custom brand programming is available for organizations requiring OEM integration. Warranty & Support: Backed by a 90-day limited warranty and available with free standard shipping on orders exceeding $99, this transceiver provides outstanding value for long-distance optical networking needs.
