The JBX02111 1000BASE-BX10-D SFP Transceiver represents a cost-effective solution for extending gigabit Ethernet connectivity up to 10 kilometers over singlemode fiber infrastructure. Engineered to meet stringent industry standards and compliance requirements, this transceiver combines performance, durability, and compatibility. **Technical Specifications:** This singlemode transceiver operates at 1GB data rates with dual-wavelength transmission (1490nm transmit, 1310nm receive) enabling full-duplex communication over simplex fiber arrangements. The 9/125 micron singlemode fiber core specification ensures minimal signal loss and dispersion over extended distances. Compliant with IEEE 802.3ah standards and SFF-8472 digital diagnostic monitoring, this module provides comprehensive performance visibility. **Build Quality & Safety:** Constructed with a metal case and integrated laser transmitter assembly, the JBX02111 delivers robust performance in demanding environments. Safety features include Class 1 laser certification, TÜV approval, and UL/FDA compliance per 21CFR 1040.10. RoHS/ELV directives compliance ensures environmental responsibility without compromising functionality. **Compatibility & Installation:** Designed as a direct replacement for Juniper SFP-1GT14R13BX10-I modules, this transceiver integrates seamlessly into existing Juniper networks. The simplex LC/UPC connector provides secure, low-loss connections with industry-standard fiber patch cords. Custom brand programming is available for OEM applications. **Performance Range:** With an extended operating temperature range of -40 to 85°C, this transceiver performs reliably in diverse climates and indoor/outdoor installations. The 10km transmission reach makes it ideal for campus networks, metropolitan area networks (MANs), and long-distance point-to-point connections. **Value & Support:** Offered with free standard shipping on orders exceeding $99 and backed by a 90-day limited warranty, the JBX02111 provides excellent value for network infrastructure investments. Ships from multiple US locations (Danville, CA and Beaufort, SC) for expedited delivery. Whether upgrading existing infrastructure or expanding network capacity, this Juniper-compatible SFP transceiver delivers proven performance, safety, and reliability for modern networking demands.
