The JBX02188 1000BASE-BX40-U SFP transceiver represents cutting-edge technology for extended-reach fiber optic networking. This module is engineered to provide 1GB data rates over single-mode fiber (9/125μm) at distances up to 40km, significantly extending network coverage compared to standard short-reach modules. Key Technical Specifications: This transceiver operates using bidirectional (BiDi) technology, transmitting at 1310nm and receiving at 1490nm simultaneously over a single fiber strand. The simplex LC/UPC connector ensures secure, low-loss connections with minimal signal degradation. Qualified to SFF-8472 extended-reach specifications, it exceeds standard IEEE 802.3ah requirements, delivering superior performance for demanding network environments. Compatibility & Integration: As a direct replacement for Cisco GLC-BX-U40 (OEM P/N: MA-SFP-1GB-BX40-U), this module integrates seamlessly into existing Cisco-compatible network equipment. The compact SFP form factor (5x4x2mm) fits standard SFP slots without requiring additional hardware modifications. Quality & Compliance: Manufactured to ISO standards with multiple safety certifications including Class 1 Laser designation and FDA compliance (21CFR 1040.10), this transceiver prioritizes safety and reliability. RoHS and ELV compliance ensures environmental responsibility and regulatory adherence across global markets. The durable metal case with integrated laser transmitter provides years of dependable service. Applications: Ideal for telecommunications networks, metro area networks (MANs), enterprise campuses, and data center interconnects requiring extended-reach connectivity without deploying additional amplification equipment. Perfect for organizations needing cost-effective, long-distance fiber links. Operational Reliability: Operating across the extended temperature range of 0-70°C (32-158°F), this module performs consistently in diverse environmental conditions. The 90-day limited warranty provides peace of mind, backed by free standard shipping on qualifying orders. Customization Available: Custom brand programming is available for organizations requiring OEM-specific configurations, allowing seamless integration into existing network management systems and branding requirements.
