The JBX02111 1000BASE-BX10-D SFP transceiver represents an excellent choice for network professionals seeking reliable, cost-effective long-distance connectivity. This industrial-grade optical transceiver module delivers exceptional performance in demanding network environments while maintaining full compatibility with Juniper network infrastructure. **Technical Specifications:** Operating at 1000BASE-BX10-D standards, this transceiver achieves 1Gbps data rates across 10 kilometers of singlemode fiber (9/125 core size). The module employs a simplex LC/UPC fiber connector configuration, utilizing 1490nm and 1310nm wavelengths for bidirectional transmission over a single strand. This wavelength division multiplexing approach eliminates the need for duplex fiber, reducing infrastructure costs while maintaining full-duplex communication capabilities. **Build Quality and Durability:** Constructed with a robust metal case housing an integrated laser transmitter, the JBX02111 delivers industrial-grade reliability. Its wide operating temperature range of -40 to 85°C (-40 to 185°F) ensures consistent performance across diverse deployment scenarios. The module has been engineered to meet stringent safety certifications including Class 1 Laser classification, UL/FDA 21CFR 1040.10, and TUV compliance. **Compliance and Standards:** Fully RoHS and EU directive 2002/95/EC compliant, this transceiver meets modern environmental regulations. It's qualified to IEEE 802.3ah specifications and SFF-8472 standards, ensuring interoperability with standard SFP infrastructure. Custom brand programming is available for OEM applications. **Juniper Network Integration:** Designed as a direct replacement for Juniper SFP-1GT14R13BX10-I modules, the JBX02111 integrates seamlessly into existing Juniper deployments without requiring firmware updates or configuration changes. This compatibility extends to all Juniper devices supporting standard 1Gbps SFP transceiver modules. **Ideal Applications:** Perfect for enterprise campus networks, service provider rings, metropolitan area networks (MANs), and datacenter interconnections where 10km distances are required. The simplex configuration is especially valuable for organizations already investing in singlemode fiber infrastructure seeking cost optimization. **Warranty and Support:** Backed by a 90-day limited warranty with free standard shipping on orders exceeding $99, this transceiver offers exceptional value.
