The JBX01815 10GBASE-LR SFP+ transceiver module represents a critical component for modern high-speed optical networking infrastructure. Specifically engineered as a compatible replacement for Arista SFP-10G-LR modules, this transceiver enables seamless integration into existing enterprise networks without costly equipment replacements. **Key Technical Specifications:** Operating at 1310nm wavelength, the JBX01815 achieves 10-kilometer transmission distances over single-mode fiber (SMF), making it ideal for metropolitan area networks, campus interconnects, and data center uplinks. The module supports 10GBASE-LR IEEE 802.3ae standards, ensuring interoperability with certified networking equipment. With duplex LC/UPC connectors, it provides secure, low-loss fiber connections that minimize signal degradation over extended distances. **Features & Benefits:** The integrated metal case with laser transmitter design ensures optimal thermal management and laser safety (Class 1 certified). The module operates reliably across 0-70°C, accommodating diverse deployment environments from temperature-controlled data centers to outdoor network installations. RoHS and ELV compliance demonstrates environmental responsibility, while comprehensive safety certifications (UL, FDA 21CFR 1040.10, TUV) guarantee reliable operation in regulated industries. **Ideal Applications:** - Data center core switching and inter-rack connectivity - Long-distance metropolitan area network (MAN) links - High-speed campus network interconnects - Enterprise backbone upgrades - Arista switching ecosystem expansion **Compatibility & Installation:** Fully compatible with Arista switches and certified optical networking equipment supporting SFP+ form factor modules. Custom brand programming is available for organizations with specific requirements. The compact 5x4x2 dimensions ensure compatibility with standard SFP+ slots without requiring additional cabling or adapters. **Warranty & Support:** Backed by a 90-day limited warranty with domestic U.S. shipping from multiple locations (Danville, CA and Beaufort, SC). Free standard shipping applies to orders exceeding $99, providing cost-effective network upgrades for IT departments managing bandwidth expansion projects.
