The JBX01310 100GBASE-SR4 QSFP28 Transceiver represents a high-capacity, reliable solution for modern data center and enterprise network infrastructures. Engineered to deliver 100 gigabit Ethernet performance, this multimode optical transceiver operates at an 850-nanometer wavelength, the industry standard for short-reach, high-speed data transmission. **Key Technical Specifications:** This QSFP28-form-factor transceiver achieves 100-meter transmission distances over OM4 multimode fiber, making it perfectly suited for intra-data center connections, campus backbones, and high-speed local area networks. The dual MTP/MPO-12 fiber connectors with UPC polish provide superior signal integrity and minimal insertion loss. Operating temperatures range from 0 to 70°C (32 to 158°F), ensuring reliable performance in diverse environmental conditions. **Standards Compliance & Certification:** Qualified to IEEE 802.3bm specifications and compliant with QSFP28 Multi-Source Agreement (MSA) standards, this transceiver guarantees interoperability across certified networking equipment. Safety certifications include Class 1 Laser designation, TUV approval, and UL/FDA compliance (21CFR 1040.10). Full RoHS and ELV directive compliance ensures environmental responsibility and regulatory adherence. **Compatibility & Replacement:** Designed as a direct replacement for Brocade XBR-100G-SR4-01 optical modules, the JBX01310 provides seamless integration into existing Brocade infrastructure without requiring reconfiguration or firmware updates. Custom brand programming is available for OEM applications and bulk deployments. **Construction & Durability:** Featuring a durable metal case with integrated laser transmitter technology, this transceiver withstands the rigors of data center environments. Compact dimensions (5.0" x 4.0" x 2.0") facilitate easy installation in standard QSFP28 ports. **Value Proposition:** Offering exceptional performance-to-cost ratio, the JBX01310 enables organizations to upgrade network capacity without expensive equipment replacement. Free standard shipping on orders over $99 and a 90-day limited warranty provide additional customer assurance. Ships from strategic U.S. locations in California and South Carolina for expedited delivery. **Applications:** Ideal for data center upgrades, high-speed campus networks, enterprise backhaul, and cloud service provider infrastructure requiring 100GB interconnectivity over relatively short distances. Perfect for organizations standardized on Brocade switching platforms seeking cost-effective performance enhancement.
