The JBX01795 10GBASE-ER SFP+ transceiver is a professional optical transmission module engineered for demanding network infrastructure applications. This extended-range transceiver excels in scenarios requiring high-speed data transmission over significant distances, making it ideal for data center interconnections, enterprise campus networks, and metropolitan area network (MAN) deployments. Key Technical Specifications: Operating at 10 gigabits per second, this module utilizes 1550nm wavelength transmission optimized for extended-reach performance over single-mode fiber. The 40-kilometer transmission distance capability eliminates the need for intermediate repeaters in most enterprise network architectures, reducing infrastructure complexity and maintenance costs. Connectivity & Compatibility: Equipped with duplex LC/UPC connectors featuring 9/125 micron single-mode fiber cores, this transceiver ensures optimal light transmission with minimal signal loss. Fully compatible with Extreme Networks equipment, including the 10G-ER-SFP40KM-ET standard, it integrates seamlessly into existing network infrastructure. Robustness & Compliance: Constructed with a metal case housing an integrated laser transmitter, the module withstands demanding environmental conditions with operating temperatures spanning -10°C to 85°C (14°F to 185°F). Compliant with IEEE 802.3ae specifications, RoHS/ELV directives, and featuring Class 1 Laser certification, this transceiver meets international safety and environmental regulations. Quality Assurance: Each unit includes custom brand programming capability and comes backed by a comprehensive 90-day limited warranty. Ships from multiple U.S. locations (Danville, CA and Beaufort, SC) with free standard shipping on qualifying orders. Applications & Use Cases: Ideal for organizations expanding network capacity, upgrading infrastructure, or establishing redundant high-speed links across geographically dispersed facilities. Suitable for financial institutions, healthcare networks, research facilities, and enterprise organizations requiring reliable, standards-compliant optical connectivity.
