The JBX02217 1000BASE-BX80-U SFP transceiver represents a cutting-edge solution for enterprises demanding extended-reach, high-performance network connectivity. Engineered to deliver gigabit Ethernet speeds over impressive 80-kilometer distances on singlemode fiber infrastructure, this module eliminates the need for costly amplification equipment in long-haul deployments. **Key Technical Specifications:** Operating at 1550/1490nm wavelengths, this BiDi (bidirectional) transceiver utilizes singlemode fiber (9/125 micron core) for maximum distance and signal integrity. The simplex LC/UPC connector ensures reliable, low-loss connections in professional networking environments. Qualified to SFF-8472 standards with extended-reach capabilities beyond IEEE 802.3ah specifications, it supports demanding enterprise applications. **Outstanding Features:** Compact SFP form factor (5x4x2mm) fits seamlessly into standard SFP slots on Arista switches and compatible equipment. The precision laser transmitter housed in a durable metal case ensures consistent performance across temperature variations (0-70°C). Advanced bidirectional technology maximizes fiber utilization, reducing cabling requirements in point-to-point deployments. **Compliance & Safety:** Fully RoHS-compliant and EU directive 2002/95/EC certified, this transceiver meets stringent environmental standards. Class 1 laser certifications from FDA (21CFR 1040.10), TUV, and UL guarantee safety in professional installations. **Perfect For:** Data center interconnects, campus network backbone connections, remote site connectivity, and service provider deployments requiring long-distance, cost-effective fiber optic solutions. **Warranty & Support:** Included 90-day limited warranty with custom brand programming available. Free standard shipping on orders exceeding $99, shipped from convenient US locations (Danville, CA and Beaufort, SC).
