The JBX01809 10GBASE-ER SFP+ transceiver represents professional-grade optical connectivity for enterprise networks requiring extended transmission distances. Engineered to IEEE 802.3ae specifications, this module delivers consistent 10 Gigabit Ethernet performance over 40 kilometers of single-mode fiber infrastructure, making it an excellent choice for metropolitan area networks (MANs), data center interconnects, and long-haul network segments. Key Technical Features: Operating at the 1550nm wavelength, this transceiver optimizes signal transmission through single-mode fiber while minimizing attenuation over extended distances. The Duplex LC/UPC connector configuration provides superior signal quality and reduced insertion loss compared to alternative connector types. The integrated metal case houses a precision laser transmitter and photodetector assembly, ensuring stable operation across temperature ranges from 0 to 70°C (32 to 158°F). Compatibility and Integration: Designed as a direct replacement for Juniper SFPP-10GE-ER modules, the JBX01809 seamlessly integrates into existing Juniper network infrastructures without requiring firmware updates or complex reconfiguration. Support for SFF-8431 and SFF-8472 MSA standards guarantees interoperability with compliant equipment. Compliance and Certification: This transceiver meets rigorous international safety and environmental standards, including RoHS directive 2002/95/EC compliance, Class 1 Laser certification, TUV, UL, and FDA 21CFR 1040.10 approval. These certifications confirm safe operation in professional environments while adhering to global environmental regulations. Applications: Perfect for data center expansion, campus network interconnects, disaster recovery links, and service provider backbone networks. The 40km range eliminates the need for signal regeneration equipment in many deployments, reducing infrastructure costs and complexity. Warranty and Support: Backed by a 90-day limited warranty. Custom brand programming available for enterprise deployments. Ships from multiple U.S. locations with free standard shipping on orders over $99.
