The JBX01811 represents professional-grade optical transceiver technology designed for critical enterprise network infrastructure. As a 10GBASE-ER SFP+ module, it delivers the performance, reliability, and compatibility required for modern data center and wide-area network applications. **Superior Extended-Range Capabilities** With 1550nm wavelength technology and 40km transmission distance over single-mode fiber, this transceiver enables long-distance network connections without requiring intermediate repeaters. This extended range makes it ideal for campus interconnects, metro-area networks, and disaster recovery site links where standard transceivers fall short. **Full Juniper Ecosystem Compatibility** Designed as a direct replacement for Juniper's SFPP-10GE-ER-XT transceiver, the JBX01811 integrates seamlessly into existing Juniper switch and router environments. This compatibility ensures plug-and-play deployment with zero firmware or configuration complications. **Robust Engineering Standards** Built to IEEE 802.3ae specifications and qualified per SFF-8431 and SFF-8472 standards, this transceiver meets international compliance requirements including RoHS/ELV directives and EU regulations. Comprehensive safety certifications (Class 1 Laser, UL, FDA 21CFR 1040.10, TUV) ensure safe operation in any enterprise environment. **Technical Specifications** The module features 9/125 single-mode fiber core compatibility with duplex LC/UPC connectors—the industry standard for professional installations. Its compact 5x4x2mm form factor fits standard SFP+ slot sizes, while the metal case with integrated laser transmitter provides durability and thermal management for consistent performance. **Operational Reliability** With an industrial operating temperature range of -10 to 85°C, the JBX01811 performs reliably in diverse deployment scenarios. The 90-day limited warranty provides confidence in your investment, while custom brand programming options allow OEM integration for channel partners and system integrators. **Applications** Ideal for data center-to-data center replication, metropolitan area networks, long-distance backup links, and campus fiber infrastructure expansions. Perfect for organizations requiring 10 Gigabit Ethernet connectivity beyond standard 300-meter limitations.
