The JBX01418 100GBASE-ER4-Lite QSFP28 transceiver represents a cutting-edge solution for organizations requiring high-speed, long-distance optical connectivity. This extended-reach transceiver is specifically designed to bridge metropolitan-area distances while maintaining 100 Gigabit Ethernet performance. Technical Specifications: The transceiver operates at 1310nm wavelength, optimized for extended-reach transmission over standard singlemode fiber with a 9/125 micron core. It achieves 100Gbps data rates while maintaining signal integrity across distances up to 25 kilometers—substantially farther than typical ER4 variants. This makes it perfect for campus networks, city-wide deployments, and data center campus interconnections. Connectivity & Compatibility: Equipped with Duplex LC/UPC connectors, the transceiver ensures low insertion loss and minimal reflectance. Full compatibility with Cisco QSFP-100G-ERL-S modules means seamless integration into existing Cisco infrastructure without configuration changes or firmware updates. Compliance & Safety: Manufactured with a metal case housing a precision laser transmitter, this optical module meets stringent industry standards including IEEE 802.3bm and QSFP28 MSA specifications. RoHS and ELV compliance ensures environmentally responsible manufacturing, while Class 1 laser certification and FDA compliance (21CFR 1040.10) guarantee user safety. Reliability & Support: The robust design operates reliably across 0-70°C temperature ranges, suitable for both air-conditioned data centers and field deployments. A 90-day limited warranty provides peace of mind, and custom brand programming is available for enterprise OEM requirements. Applications: Ideal for enterprise data centers, metropolitan area networks, campus interconnects, and service provider networks requiring high-speed, long-reach connectivity without degradation. The ER4-Lite variant offers superior distance capabilities compared to SR4 modules while remaining cost-effective for organizations not requiring ultra-long ranges. Logistics: Ships from strategically located warehouses in Danville, CA and Beaufort, SC. Free standard shipping applies to orders exceeding $99, making deployment economical at scale.
