The JBX02182 1000BASE-BX40-D SFP Transceiver represents cutting-edge optical networking technology designed for organizations requiring extended-reach connectivity. This simplex LC/UPC transceiver excels in long-distance applications where traditional SFP modules fall short, delivering consistent 1GB performance across 40 kilometers of singlemode fiber infrastructure. **Key Technical Specifications:** This transceiver operates on a 9/125 singlemode fiber core with bidirectional wavelengths (1550nm transmit/1310nm receive), enabling simultaneous data transmission and reception over a single fiber strand. The module adheres to SFF-8472 specifications and extends beyond IEEE 802.3ah standards, ensuring compatibility with modern network architectures. **Superior Compatibility & Integration:** Purpose-built for Juniper environments, the JBX02182 serves as a direct replacement for OEM part numbers EX-SFP-GE40KT15R13 and SFP-GE40KT15R13. This seamless compatibility eliminates integration challenges and reduces deployment time for network upgrades or expansions. **Robust Quality & Compliance:** Manufactured with precision-engineered metal housing and advanced laser transmitter technology, this transceiver meets rigorous international safety standards: Class 1 Laser certification, UL/FDA compliance (21CFR 1040.10), and TUV verification. Full RoHS and EU directive 2002/95/EC compliance ensures environmental responsibility. **Operational Reliability:** Rated for 0-70°C operating temperatures, this module performs consistently across diverse deployment environments. The compact 5x4x2mm form factor fits standard SFP slots, while custom brand programming options enable fleet-wide standardization. **Value & Support:** Each unit includes a 90-day limited warranty, with free standard shipping on orders exceeding $99. Sourced from reliable manufacturing locations and backed by industry expertise, the JBX02182 delivers enterprise-grade performance at competitive pricing. Ideal for ISPs, data center operators, and enterprises expanding network reach without fiber infrastructure replacement.
