The JBX01487 100GBASE-PSM4 QSFP28 transceiver represents cutting-edge optical networking technology designed for enterprise-grade applications requiring high bandwidth and extended transmission distances. This module is fully compatible with HPE systems, directly replacing OEM part numbers JQ028A and Q8J73A, ensuring seamless integration into existing infrastructure without compatibility concerns. **Technical Specifications:** Operating at 100GB data rates, this transceiver utilizes 1310nm wavelength technology optimized for single-mode fiber (9/125μm core) transmission up to 500 meters. The QSFP28 form factor provides compact density, enabling high-port-count configurations in modern switch architectures. MTP/MPO connectors ensure reliable, high-count fiber connections typical of parallel optics deployments. **Performance & Reliability:** Qualified to IEEE 802.3bm specifications, the module undergoes rigorous testing to ensure consistent performance across temperature ranges of 0-70°C (32-158°F). The integrated laser transmitter is Class 1 laser-certified, meeting FDA 21CFR 1040.10 and TUV/UL safety requirements. RoHS and ELV directive compliance (EU 2002/95/EC) demonstrates commitment to environmental standards and reduced hazardous substances. **Applications:** Ideal for data center interconnects, campus backbone networks, metropolitan area networks (MANs), and long-distance telecommunications. The 500m reach over single-mode fiber supports applications requiring extended transmission without signal degradation, critical for organizations planning scalable network infrastructure. **Quality Assurance:** Each transceiver includes a 90-day limited warranty, backed by professional support. Custom brand programming is available for organizations requiring vendor-specific configurations. Manufactured in Vietnam and China using proven optical component engineering. **Shipping & Support:** Available from Danville, CA and Beaufort, SC distribution centers, with complimentary standard shipping on orders exceeding $99. The compact dimensions (5" x 4" x 2") and metal construction ensure safe transport and long-term durability in network equipment racks.
