The JBX02200 is a premium-grade 1000BASE-BX40-U SFP optical transceiver module designed for telecommunications and data center professionals seeking reliable extended-reach connectivity. This module represents the cutting edge of optical networking technology, delivering exceptional performance for demanding enterprise environments. Advanced Technology & Design: Leveraging bidirectional (BiDi) transmission technology, the JBX02200 efficiently utilizes single fiber strands by employing wavelength division multiplexing (WDM). The module transmits at 1310nm while simultaneously receiving at 1550nm, or vice versa, doubling effective fiber capacity without requiring duplex connections. This innovative approach reduces infrastructure costs while maintaining full 1GB throughput. Specifications & Performance: Built on 9/125 single-mode fiber architecture, this transceiver achieves impressive 40-kilometer transmission distances—ideal for campus interconnects, metropolitan area networks (MANs), and long-distance point-to-point links. The module meets SFF-8472 extended-reach BiDi specifications and operates reliably across 0-70°C temperature ranges, accommodating diverse deployment environments from climate-controlled data centers to outdoor equipment installations. Compatibility & Integration: Fully compatible with Cisco's GLC-BX35-U40 specification, the JBX02200 integrates seamlessly into existing Cisco infrastructure. The simplex LC/UPC connector ensures low-loss optical connections with excellent return loss characteristics, while the metal case construction provides electromagnetic shielding and enhanced durability. Compliance & Certification: This module exceeds industry standards with comprehensive certifications including RoHS/ELV compliance, Class 1 laser safety designation, and UL/FDA approvals under 21CFR 1040.10. These certifications guarantee safe operation and environmental responsibility. Applications: Ideal for enterprise networks, Internet Service Providers (ISPs), telecommunications facilities, and data center operators requiring cost-effective long-distance connectivity. Perfect for backbone network expansion, disaster recovery links, and metropolitan campus networking. Warranty & Support: 90-day limited warranty with custom brand programming available upon request. Free standard shipping on orders exceeding $99, with convenient fulfillment from California or South Carolina locations.
