The JBX01422 100GBASE-ER4-Lite QSFP28 transceiver represents cutting-edge optical networking technology designed specifically for enterprise data centers, service providers, and campus networks requiring high-speed, extended-distance connectivity. This module delivers impressive 100Gb/s data transmission capability over 40km of singlemode fiber, making it ideal for inter-datacenter links, metropolitan area networks, and long-distance campus deployments. Key Technical Specifications: This QSFP28 module operates on singlemode fiber (9/125 core), utilizing duplex LC/UPC connectors for reliable, precision-aligned connections. The module complies with IEEE 802.3bm standards and QSFP28 MSA specifications, ensuring interoperability across certified platforms. Operating temperature range of 0-70°C accommodates diverse environmental conditions, while forward error correction (FEC) technology optimizes signal integrity over extended distances. Performance and Reliability: The metal case construction with integrated laser transmitter components provides enhanced durability and thermal management. RoHS/ELV compliance ensures environmental responsibility and regulatory adherence. Qualified for Extreme Networks equipment, including direct compatibility with 100G-ER4LT-QSFP40KM and 10403-ER4L systems, simplifying deployment and integration. Applications and Use Cases: Perfect for metropolitan-area networking where 40km reach eliminates repeater infrastructure. Ideal for disaster recovery links, geographically distributed data center synchronization, and enterprise campus fiber backbone upgrades. The extended 40km capability reduces intermediate equipment costs while maintaining 100G performance standards. Compliance and Safety: Class 1 laser certification (LN #50 7/2001) and TUV/UL/FDA compliance (21CFR 1040.10) demonstrate adherence to international safety standards. RoHS directive compliance (EU 2002/95/EC) reflects commitment to hazardous substance reduction. Value Proposition: Offering premium performance at competitive pricing, the JBX01422 includes free standard shipping on orders exceeding $99 and custom brand programming options. The 90-day limited warranty provides purchase confidence. Whether upgrading existing 100G infrastructure or designing new networks, this transceiver delivers exceptional reliability and performance for mission-critical optical connectivity requirements.
