The JBX01399 100GBASE-CWDM4 QSFP28 transceiver represents a premium solution for high-speed optical networking infrastructure. This module is engineered to deliver sustained 100GB data rates, making it ideal for data center interconnects, cloud computing environments, and enterprise backbone networks requiring exceptional bandwidth and reliability. Key Technical Specifications: The transceiver utilizes coarse wavelength division multiplexing (CWDM4) technology to transmit and receive data across four distinct wavelengths simultaneously over a single fiber pair. Its 2km reach over standard singlemode fiber (9/125 micron core) makes it suitable for campus-area networks and moderate-distance data center deployments. The duplex LC/UPC connectors feature ultra-polish finishes that minimize insertion loss and maintain signal integrity across transmission distances. Compatibility & Integration: Fully compatible with NVIDIA Mellanox networking systems, including the 980-9I17Q-00CM00, MMA1L30-CM, and 980-9I63F-00CM00 modules, this transceiver serves as a reliable replacement or expansion component. It conforms to QSFP28 MSA (Multi-Source Agreement) standards and IEEE 802.3bm specifications, ensuring seamless integration with existing infrastructure. Quality & Compliance: Manufactured in Vietnam and China with rigorous quality control, the module features a durable metal case protecting sensitive laser transmitter components. It is RoHS compliant (EU Directive 2002/95/EC) and carries comprehensive safety certifications including Class 1 Laser designation, TUV, UL, and FDA 21CFR 1040.10 compliance. Operating temperature range of 0-70°C ensures stable performance in various data center environments. Value & Support: Each unit includes custom brand programming availability for OEM applications, 90-day limited warranty coverage, and free standard shipping on orders exceeding $99. Whether upgrading existing systems or building new infrastructure, this transceiver delivers enterprise-grade performance and reliability at competitive pricing. Ships from convenient US locations (Danville, CA and Beaufort, SC) for rapid deployment.
