The JBX02195 1000BASE-BX40-U SFP Transceiver represents enterprise-grade optical connectivity engineered for demanding network applications requiring extended transmission distances. With a 40-kilometer reach over single-mode fiber (9/125 micron core), this transceiver eliminates the need for additional amplification or intermediate repeaters in long-haul deployments, reducing infrastructure complexity and total cost of ownership. **Key Technical Features:** This bidirectional optical transceiver operates at 1Gbps using wavelength-division multiplexing (1310/1490nm), enabling full-duplex communication across a single fiber strand. The simplex LC/UPC connector ensures low-loss, repeatable connections with minimal signal degradation. Its compact SFP form factor (5mm x 4mm x 2mm) provides compatibility with standard SFP slots in switches, routers, and network appliances. **Performance & Reliability:** Manufactured to SFF-8472 specifications and exceeding IEEE 802.3ah standards, this module delivers consistent performance in diverse networking environments. The metal case construction with integrated laser transmitter provides electromagnetic shielding and thermal management for stable operation across 0-70°C ambient temperatures. **Compliance & Safety:** Fully RoHS and ELV compliant, the transceiver meets EU directive 2002/95/EC environmental standards. Safety certifications include Class 1 Laser designation, TUV, UL, and FDA 21CFR 1040.10 compliance, ensuring workplace safety and regulatory adherence. **Application Scenarios:** Ideal for enterprise backbone connectivity, campus network expansions, data center interconnects, and telecommunications infrastructure. Fortinet FG-TRAN-BX40-U compatibility makes it perfect for organizations standardized on Fortinet security appliances and network equipment. **Warranty & Support:** Backed by a 90-day limited warranty with custom brand programming available for OEM requirements. Free standard shipping on orders exceeding $99, with shipments from strategically located U.S. warehouses in California and South Carolina for expedited delivery.
