The JBX01247 40GBASE-LR4L QSFP+ transceiver represents premium optical networking technology designed for mission-critical data center and enterprise applications requiring ultra-high-speed connectivity. This advanced module supports 40 gigabit per second data rates, delivering the bandwidth necessary for modern cloud infrastructure, high-frequency trading platforms, and large-scale data migrations. **Technical Excellence** Engineered to IEEE 802.3ba and SFF-8436 specifications, this QSFP+ transceiver features a robust design with metal housing and integrated laser transmitter technology. The 9/125 single-mode fiber core ensures signal purity and minimal attenuation, while the duplex LC/UPC connectors provide secure, low-loss connections essential for consistent performance. **Extended Range Capability** With a 2km transmission range over single-mode fiber, this transceiver bridges longer distances than multi-mode alternatives, reducing the need for regeneration equipment and simplifying network architecture. This extended range proves particularly valuable in campus networks and metropolitan area networks (MANs). **Seamless Integration** Directly compatible with Extreme Networks AA1404002-E6 equipment, the JBX01247 integrates seamlessly into existing infrastructure. Custom brand programming is available for OEM requirements, providing flexibility for enterprise deployments. **Industry-Leading Safety & Compliance** Rigorous safety certifications including Class 1 Laser designation, TUV, UL/FDA approval (21CFR 1040.10), and RoHS/ELV directive compliance ensure your network meets regulatory requirements. Operating temperature range of 0-70°C accommodates diverse deployment environments. **Operational Advantages** The transceiver's compact 5x4x2-inch dimensions facilitate easy installation in high-density equipment. A 90-day limited warranty provides peace of mind, backed by rapid shipping from multiple U.S. locations. Free standard shipping on orders exceeding $99 reduces total cost of ownership. Ideal for network administrators, systems integrators, and data center professionals seeking reliable, standards-compliant 40GB connectivity.
