The JBX01679 10GBASE-BX10-D SFP+ transceiver represents a cost-effective solution for organizations requiring extended-reach optical networking capabilities. Engineered to IEEE 802.3ae specifications, this module delivers reliable 10 gigabit-per-second performance across single-mode fiber infrastructure up to 10 kilometers. **Key Technical Features:** This simplex transceiver utilizes a single-strand, single-mode fiber (9/125 micron core) with LC/UPC connectors, enabling unidirectional data transmission. The compact SFP+ form factor (5x4x2mm) fits directly into standard SFP+ ports on switches, routers, and network interface cards. Operating temperature range of -40 to 85°C ensures reliable performance in diverse environments from data centers to outdoor installations. **Performance & Compatibility:** Direct Cisco SFP-10G-BXD-I compatibility ensures plug-and-play integration with Cisco networking equipment. IEEE 802.3ae qualification guarantees standards-compliant operation. The metal case construction houses advanced laser transmitter technology, delivering consistent optical output throughout the transceiver's lifespan. **Safety & Compliance:** Comprehensive certifications include Class 1 laser safety, RoHS/ELV directive compliance, and approvals from TUV and FDA (21CFR 1040.10). These certifications ensure safe operation in regulated environments and confirm environmental responsibility. **Ideal Applications:** - Campus interconnects and backbone networks - Metropolitan area networks (MANs) - Long-distance data center replication - Remote site connectivity - Carrier and service provider networks **Value-Added Services:** Custom brand programming available for integration with existing infrastructure tracking systems.
