The JBX01892 10GBASE-ZR SFP+ transceiver represents a cost-effective solution for enterprises requiring extended-reach optical networking capabilities. Specifically engineered to replace Arista's SFP-10G-ZR modules, this transceiver delivers uncompromised performance for long-distance data transmission. **Key Technical Specifications:** Operating at 1550nm wavelength, the JBX01892 supports 10Gbps data rates over single-mode fiber distances up to 80 kilometers. The 9/125 micron single-mode fiber core provides low attenuation and chromatic dispersion characteristics essential for extended-reach applications. The duplex LC/UPC connectors ensure maximum signal integrity with minimal insertion loss, while the industry-standard SFF-8431 and SFF-8472 compliance guarantees compatibility across diverse networking ecosystems. **Reliability and Compliance:** This optical transceiver is manufactured to the highest standards, featuring a durable metal case with integrated laser transmitter technology. It holds certifications for Class 1 laser safety (LN #50 7/2001), TUV, UL/FDA (21CFR 1040.10) approval, and RoHS/ELV directive compliance. The module operates reliably across 0-70°C temperature ranges, making it suitable for varied deployment environments. **Ideal Applications:** Perfect for service providers, data centers, and enterprise networks requiring metropolitan area network (MAN) connectivity. The 80km transmission capability eliminates the need for intermediate regeneration, reducing infrastructure complexity and total cost of ownership. Commonly deployed for campus interconnections, disaster recovery links, and carrier-grade network backhaul. **Compatibility and Integration:** Fully compatible with Arista networking platforms, this module integrates seamlessly into existing deployments. Custom brand programming is available for specific organizational requirements. Ships from multiple US locations with free standard shipping on orders exceeding $99, ensuring rapid deployment. **Warranty and Support:** Backed by a 90-day limited warranty, providing peace of mind on your optical networking investment.
