The JBX01448 100GBASE-LR4 QSFP28 Transceiver represents a cutting-edge solution for high-capacity network infrastructure requiring long-distance optical connectivity. Engineered to deliver 100 gigabits per second of throughput, this module is specifically designed for enterprises seeking cost-effective alternatives to OEM transceivers without compromising performance or reliability. **Technical Specifications:** This QSFP28 form-factor transceiver operates at 100Gbps over single-mode fiber with a maximum transmission distance of 10 kilometers. The module utilizes 9/125 micrometer single-mode fiber with duplex LC/UPC connectors, providing industry-standard connectivity. Fully qualified to IEEE 802.3bm specifications and QSFP28 MSA standards, it ensures compatibility with existing network infrastructure. **Compatibility & Integration:** The JBX01448 is engineered as a direct replacement for Cisco's QSFP-100G-LR4-I transceiver (OEM part number). This compatibility extends to Cisco-based data center networks, making it an ideal choice for organizations looking to optimize capital expenditures while maintaining vendor ecosystem integrity. Custom brand programming is available for seamless integration into existing inventory management systems. **Performance & Reliability:** With an operating temperature range of -40°C to 85°C, this transceiver maintains peak performance across diverse environmental conditions. The metal case with integrated laser transmitter provides superior electromagnetic shielding and thermal management. All modules comply with RoHS and ELV directives, demonstrating commitment to environmental sustainability. **Safety & Compliance:** Comprehensive safety certifications including Class 1 Laser, TUV, UL, and FDA 21CFR 1040.10 compliance ensure safe operation in production environments. These certifications reflect rigorous testing and quality assurance protocols. **Applications:** Ideal for enterprise data centers, inter-datacenter connectivity, metropolitan area networks (MANs), and service provider backbone networks requiring high-speed, long-distance optical transmission. The 10km reach enables connection across campus networks and larger metropolitan areas without requiring intermediate amplification. **Shipping & Support:** Eligible for free standard shipping on orders over $99, with fulfillment from strategically located warehouses in California and South Carolina. Backed by a 90-day limited warranty providing peace of mind and support for your network investments.
