The 100GBASE-ER4-Lite QSFP28 Transceiver Module represents the pinnacle of modern optical networking technology, specifically designed for organizations requiring high-capacity, extended-reach connectivity within their network infrastructure. Designated as model JBX01429, this optical transceiver module delivers exceptional performance specifications that meet the demanding requirements of contemporary enterprise and service provider networks. ## Technical Excellence and Performance This transceiver operates at 100GB data rates, leveraging the proven ER4-Lite standard for singlemode fiber transmission. The 40km transmission distance over standard 9/125 singlemode fiber (SMF) provides superior reach compared to standard datacenter optics, enabling cost-effective connectivity across extended distances without requiring optical amplification systems. The module achieves strict compliance with IEEE 802.3bm specifications and QSFP28 Multi-Source Agreement (MSA) standards, ensuring compatibility across diverse networking environments. ## Connectivity and Interface Design The duplex LC/UPC fiber connectors provide superior signal integrity with minimal back-reflection, essential for maintaining signal quality over extended 40km links. The LC/UPC design ensures precise alignment and reduced insertion loss, critical factors in long-distance optical transmission. The standard QSFP28 form factor ensures seamless integration with existing network equipment and infrastructure. ## Compatibility and Integration This transceiver is explicitly engineered as a compatible replacement for Palo Alto Networks PAN-QSFP28-100GBASE-ER4 modules, offering organizations a cost-effective alternative without sacrificing performance or reliability. The module's compatibility extends across QSFP28-equipped networking platforms, making it an ideal choice for organizations with diverse network architectures. ## Environmental and Safety Compliance Manufactured in Vietnam and China with rigorous quality controls, this transceiver exceeds international environmental standards. Full RoHS (Restriction of Hazardous Substances) and ELV (End of Life Vehicles) Directive 2002/95/EC compliance ensures responsible manufacturing and end-of-life recycling. The module holds Class 1 Laser certification (FDA 21CFR 1040.10, LN #50 7/2001) and TUV/UL safety certifications, meeting stringent global safety requirements. ## Operating Specifications and Reliability The metal case with integrated laser transmitter protects sensitive optical components while maintaining optimal thermal characteristics. Operating temperature range of 0-70°C (32-158°F) supports diverse deployment environments from climate-controlled data centers to outdoor network installations. The 90-day limited warranty provides essential product assurance. ## Ideal Applications Perfect for data center interconnects, campus backbone networks, metropolitan area networks (MANs), and service provider core network expansion. Organizations requiring 100GB connectivity across distances up to 40km will benefit from this transceiver's superior performance and compatibility. Custom brand programming is available for organizations requiring proprietary configurations. ## Value Proposition With free standard shipping on orders over $99 from strategically located distribution centers in Danville, CA and Beaufort, SC, this transceiver offers immediate availability and cost-effective delivery. The combination of proven optical technology, extensive compliance certifications, and Palo Alto Networks compatibility makes this module an intelligent choice for forward-thinking network administrators seeking reliable, cost-effective 100GB connectivity solutions.
