The JBX01202 is a professional-grade 40GBASE-ER4 QSFP+ optical transceiver designed for organizations requiring high-speed, long-distance fiber optic connectivity. As a direct replacement for Dell part number 407-BBVI, this transceiver integrates seamlessly into existing Dell infrastructure while offering exceptional value and reliability. **Technical Excellence**: This module delivers 40GB data rates over singlemode fiber (9/125 core) with an impressive 40km transmission distance. The extended reach (ER4) classification makes it ideal for metro area networks, campus backbone connections, and data center interconnections where longer spans are necessary. Full IEEE 802.3ba qualification ensures standards-based performance and vendor interoperability. **Precision Connectivity**: Equipped with duplex LC/UPC connectors, the JBX01202 provides the low-loss, low-reflectance connection required in modern optical networks. The UPC (Ultra-Polished Connector) finish minimizes signal degradation and maintains signal integrity across the full 40km distance. **Robust Construction**: The metal case houses precision laser transmission components protected by comprehensive safety certifications including Class 1 Laser designation and TUV/UL/FDA approval per 21CFR 1040.10. This enterprise-class build quality ensures years of dependable operation in mission-critical environments. **Environmental Compliance**: Manufactured in Vietnam and China, the JBX01202 meets stringent RoHS and ELV directives (EU 2002/95/EC), supporting sustainable procurement initiatives while maintaining full performance specifications. **Operational Flexibility**: Operating reliably across 0-70°C (32-158°F), this transceiver adapts to diverse installation environments from controlled data centers to field deployments. Custom brand programming is available for organizations requiring private-label solutions. **Value Proposition**: With free standard shipping on orders exceeding $99 and 90-day limited warranty coverage, the JBX01202 offers enterprise networking at competitive pricing. Ships from U.S. locations (Danville, CA and Beaufort, SC) for rapid deployment. Whether you're upgrading legacy 407-BBVI installations or building new fiber infrastructure, this transceiver delivers proven Dell compatibility, certified performance, and exceptional reliability.
