The JBX01427 100GBASE-ER4-Lite QSFP28 optical transceiver represents cutting-edge technology for modern enterprise and data center networking environments. This specialized module combines high-speed 100Gbps transmission capabilities with extended 40km reach over single-mode fiber, offering an exceptional balance of performance and distance coverage for mid-range network deployments. Technical Excellence: Engineered to IEEE 802.3bm specifications, this QSFP28 transceiver incorporates forward error correction (FEC) technology to ensure pristine signal integrity across longer distances. The 9/125 micrometer single-mode fiber core delivers superior performance compared to multi-mode alternatives, providing minimal signal degradation and attenuation over the full 40km range. The duplex LC/UPC connectors feature low insertion loss characteristics, critical for maintaining signal quality in high-bandwidth applications. Seamless Compatibility: As a direct replacement for NVIDIA Mellanox OEM part number 980-9I53X-00C000 and SPQ-CE-ER-CDFL-M, this transceiver integrates seamlessly into existing Mellanox infrastructure without requiring additional configuration or hardware modifications. Custom brand programming is available for organizations with specific requirements. Comprehensive Compliance: This optical module meets rigorous international safety and environmental standards, including Class 1 Laser certification, FDA 21CFR 1040.10 compliance, TUV certification, and RoHS/ELV directives. These certifications guarantee safe operation in any professional environment and ensure long-term regulatory compliance. Ideal Applications: • Data center interconnectivity • Campus network expansions • Metropolitan area network (MAN) implementations • High-performance computing environments • Content delivery network infrastructure • Disaster recovery and backup site connections Operational Performance: With operating temperatures spanning 0°C to 70°C (32°F to 158°F), this transceiver performs reliably in diverse environmental conditions. The metal case with integrated laser transmitter provides durability and thermal stability essential for continuous operation. Shipping and Support: Orders ship from convenient U.S. locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99. Each unit includes a 90-day limited warranty, providing peace of mind for your network investment. The JBX01427 delivers enterprise-grade optical transmission technology at a competitive price point, making it the smart choice for organizations seeking to extend network reach without compromising on speed or reliability.
