The JBX01420 100GBASE-ER4-Lite QSFP28 optical transceiver represents cutting-edge network connectivity technology designed for enterprise-grade data center and telecommunications applications. Engineered to meet the demands of modern high-speed networks, this module delivers 100 gigabit per second throughput over extended fiber distances, making it an essential component for organizations requiring scalable, reliable network infrastructure. Technical Excellence and Performance: This transceiver operates at 100GBASE-ER4-Lite specifications, supporting transmission distances up to 40 kilometers over standard 9/125 single-mode fiber (SMF). The extended range capability makes it ideal for campus-wide interconnections, metropolitan area networks (MANs), and long-haul data center-to-data center connections. Full compliance with IEEE 802.3bm standards ensures interoperability with leading network equipment manufacturers and industry-standard deployments. Connectivity and Compatibility: The duplex LC/UPC fiber connectors provide secure, low-loss signal transmission with minimal signal degradation. The module's Cisco QSFP-100G-ER4L-S compatibility enables seamless integration into existing Cisco infrastructure, significantly reducing deployment complexity and cost. The QSFP28 form factor allows for high-density port configurations in modern network switches and routers. Safety and Compliance: Extensive safety certifications including Class 1 Laser designation, TUV, UL, and FDA 21CFR 1040.10 compliance ensure safe operation in any environment. RoHS and ELV directive compliance demonstrates commitment to environmental responsibility and sustainable manufacturing practices. The metal case construction with integrated laser transmitter provides durability and protection against electromagnetic interference. Application and Use Cases: Networks requiring extended transmission distances benefit significantly from this transceiver's capabilities. Data center interconnects, enterprise campus networks, telecommunications providers, and cloud service providers rely on 100G-ER4-Lite technology for cost-effective long-distance connectivity. The forward error correction (FEC) technology ensures data integrity over extended fiber runs. Operational Reliability: With an operating temperature range of 0-70°C (32-158°F), this transceiver performs reliably across diverse environmental conditions. The 90-day limited warranty provides peace of mind, while custom brand programming availability supports OEM and white-label requirements. Manufactured in Vietnam and China to stringent quality standards, each unit undergoes rigorous testing before shipment. Value Proposition: This cost-effective alternative to OEM transceivers delivers equivalent performance at competitive pricing. Free standard shipping on orders exceeding $99, combined with rapid deployment from multiple U.S. distribution centers (Danville, CA and Beaufort, SC), ensures quick availability and minimal operational downtime. Whether upgrading existing infrastructure or deploying new network segments, the JBX01420 provides the reliability, performance, and compatibility that enterprise networks demand.
