The JBX01879 is a premium 10GBASE-LRM SFP+ optical transceiver engineered for enterprise-grade network deployments requiring reliable 10 Gigabit connectivity. Delivering impressive 300-meter transmission distances over standard OM3 multimode fiber, this module represents an ideal balance between performance and cost-effectiveness for organizations seeking to upgrade their network infrastructure without implementing expensive single-mode fiber systems. **Key Technical Specifications:** This transceiver operates at 1310nm wavelength and strictly adheres to IEEE 802.3ae standards, SFF-8431, and SFF-8472 specifications. The duplex LC/UPC fiber connector interface ensures compatibility with existing network installations while providing tool-free connection capabilities. Operating temperatures range from 0 to 70°C (32 to 158°F), supporting deployment in diverse environmental conditions. **Seamless Juniper Compatibility:** The JBX01879 is fully compatible with Juniper EX-series, QFX-series, and SRX-series switches, directly replacing OEM part numbers including EX-SFP-10GE-LRM, SFP-10G-LRM-C, QFX-SFP-10GE-LRM, and SRX-SFP-10GE-LRM. This broad compatibility eliminates the need for multiple transceiver inventories across mixed environments. **Superior Safety and Compliance:** Built with precision laser transmitter technology housed in a durable metal case, this transceiver incorporates multiple safety certifications: Class 1 Laser designation (LN #50 7/2001), TUV certification, and UL/FDA compliance (21CFR 1040.10). EU Directive 2002/95/EC (RoHS) and ELV compliance ensure environmental responsibility and regulatory adherence. **Ideal Applications:** Perfect for data center interconnects, campus network backbones, server-to-switch connectivity, and storage area networks. The 300-meter OM3 reach makes it particularly suitable for medium-distance connections within facilities without requiring the cost premium of single-mode fiber systems. **Value-Added Benefits:** Enjoy custom brand programming availability for OEM implementations, 90-day limited warranty protection, and free standard shipping on orders over $99. Ships from multiple US locations (Danville, CA and Beaufort, SC) for rapid deployment.
