The JBX01715 10GBASE-BX20-U SFP+ transceiver is a premium optical module designed for enterprise-grade network deployments requiring extended-distance, high-speed connectivity. This specialized transceiver excels in point-to-point 10 Gigabit Ethernet applications where simplex transmission over singlemode fiber is preferred. **Technical Specifications:** Operating at 10GB data rates, this transceiver utilizes a 9/125 singlemode fiber core with simplex LC/UPC connectors, enabling 20-kilometer transmission distances. The compact SFP+ form factor (5mm x 4mm x 2mm) ensures compatibility with standard transceiver slots while minimizing space requirements in network equipment. **Quality & Compliance:** Manufactured to exacting standards with metal case construction and integrated laser transmitter technology, the JBX01715 meets all relevant safety and environmental regulations. It carries Class 1 laser certification, TUV, UL, and FDA approvals per 21CFR 1040.10, ensuring safe operation in any environment. Full RoHS and ELV compliance makes this module ideal for organizations with strict environmental requirements. **Compatibility & Integration:** Specifically engineered as a direct replacement for Arista's SFP-10G-BX-U20 module, this transceiver integrates seamlessly into existing Arista network architectures. Custom brand programming is available for resellers and system integrators requiring OEM branding. **Performance & Reliability:** Qualified to IEEE 802.3ae and SFF-8431/SFF-8472 specifications, this transceiver delivers consistent performance across operating temperatures from 0 to 70°C (32 to 158°F). The extended 20km range reduces the need for intermediate equipment in campus networks, data center interconnects, and metropolitan area networks. **Support & Warranty:** Backed by a 90-day limited warranty and manufactured in Vietnam and China with quality assurance, this module represents a cost-effective solution for upgrading network infrastructure. Free standard shipping on orders exceeding $99 is available from distribution centers in Danville, CA and Beaufort, SC.
