The JBX01244 40GBASE-LR4 QSFP+ transceiver represents a high-performance solution for modern enterprise networking requirements. Designed to transmit 40GB data rates over extended distances up to 10 kilometers through single-mode fiber (SMF), this optical module is essential for data center interconnects, campus networks, and long-distance WAN applications. **Technical Specifications:** This transceiver operates on 9/125 single-mode fiber with duplex LC/UPC connectors, ensuring reliable signal transmission with minimal signal loss. The 40GBASE-LR4 standard supports wavelength division multiplexing across four lanes, optimizing fiber utilization efficiency. The module measures 5x4x2 inches with a compact QSFP+ form factor, enabling seamless integration into existing infrastructure without requiring additional space or modifications. **Compatibility & Performance:** Fully compatible with Ruckus E40G-QSFP-LR4 systems, this transceiver serves as an excellent replacement or expansion module. It operates reliably across a wide temperature range of 0-70°C (32-158°F), suitable for diverse deployment environments from climate-controlled data centers to field installations. **Certifications & Safety:** This optical module meets stringent international standards including IEEE 802.3ba specifications and SFF-8436 form factor requirements. It carries Class 1 laser safety certification, TUV, UL, and FDA 21CFR 1040.10 compliance, ensuring safe operation in professional environments. The unit is fully RoHS and ELV compliant (EU directive 2002/95/EC), reflecting commitment to environmental responsibility. **Build Quality:** Featuringdurable metal case construction with integrated laser transmitter technology, the JBX01244 delivers exceptional durability and thermal management. The precision-engineered optics minimize modal dispersion and maximize signal integrity over the full 10km transmission distance. **Value & Support:** Custom brand programming is available for OEM and enterprise customers requiring proprietary identification. The 90-day limited warranty provides peace of mind, while free standard shipping on orders exceeding $99 reduces total acquisition costs. Ships from convenient U.S. locations in California and South Carolina, ensuring rapid delivery.
