The JBX01491 100GBASE-PSM4 QSFP28 Transceiver represents cutting-edge optical networking technology designed specifically for enterprise-grade applications requiring ultra-high-speed data transmission. This specialized module delivers exceptional performance in modern data center environments, telecommunications networks, and campus area networks where 100 gigabit connectivity is essential. Technical Excellence: This transceiver utilizes advanced optical engineering with 1310nm wavelength transmission optimized for single-mode fiber (SMF) deployment. The 9/125μm fiber core ensures minimal signal degradation over the 500-meter transmission distance, providing reliable connectivity for critical network infrastructure. MTP/MPO-12/APC connectors offer high-density connections while maintaining signal integrity through APC (angled physical contact) technology that minimizes back-reflection. Compatibility & Integration: Seamlessly integrates with NVIDIA Mellanox network equipment as a direct replacement for OEM part number 980-9I16X-00C000. The QSFP28 form factor enables deployment in existing infrastructure without requiring chassis upgrades. Full compliance with IEEE 802.3bm specifications ensures interoperability across diverse networking environments. Certifications & Compliance: Comprehensive safety certifications include Class 1 Laser designation, UL/FDA 21CFR 1040.10 compliance, and TUV verification. RoHS/ELV directives ensure environmental responsibility. These certifications guarantee safe operation in temperature ranges from 0°C to 70°C, suitable for both climate-controlled data centers and field deployments. Customization & Support: Custom brand programming is available for enterprise customers requiring white-label solutions. The module ships from multiple U.S. locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99, reducing total cost of ownership. Backed by a 90-day limited warranty providing peace of mind on your investment. Applications: Ideal for data center core/edge connectivity, storage area networks (SANs), campus backbone infrastructure, and high-performance computing cluster interconnects. The 500-meter distance capability supports multi-building campus networks while maintaining 100GB transmission speeds. This transceiver module combines industrial-grade reliability, advanced optical performance, and enterprise compatibility—essential requirements for modern network infrastructure investments.
