The JBX02205 1000BASE-BX40-U SFP transceiver module represents a cost-effective solution for enterprise and service provider networks requiring extended-reach gigabit Ethernet connectivity. Engineered to replace the Juniper SFP-GE40KT13R15 directly, this transceiver combines reliability with performance for critical network infrastructure. **Extended Reach Technology** With a maximum transmission distance of 40 kilometers over single-mode fiber, this transceiver significantly extends network coverage compared to standard SFP modules limited to shorter distances. The 1310/1550nm bi-directional technology allows simultaneous transmission and reception over a single fiber strand, reducing cabling complexity and installation costs. **Comprehensive Compliance & Certification** This module meets stringent safety and environmental standards, including Class 1 Laser certification, FDA 21CFR 1040.10 compliance, TUV and UL certifications, and RoHS/ELV directives. These certifications ensure safe operation in diverse network environments while meeting regulatory requirements across global markets. **Technical Specifications** The transceiver operates with a 9/125 micron single-mode fiber core and features a simplex LC/UPC connector for standardized network integration. Its compact SFP form factor (5x4x2 dimensions) enables flexible deployment in standard network equipment. Operating temperature range of 0-70°C accommodates both indoor and outdoor installations. **Compatibility & Integration** Qualified to SFF-8472 extended-reach BiDi specifications, this module integrates seamlessly into existing Juniper infrastructure. The direct compatibility with SFP-GE40KT13R15 ensures drop-in replacement capability without configuration modifications. **Ideal Applications** Perfect for telecommunications companies, ISPs, data center interconnects, university campuses, and enterprise networks requiring extended connectivity. The 1GB data rate supports standard Ethernet applications while the extended range eliminates distance limitations for critical network segments. **Warranty & Support** Backed by a 90-day limited warranty and custom brand programming availability, ensuring flexibility for enterprise deployments. Ships from multiple US locations (Danville, CA and Beaufort, SC) with complimentary standard shipping on orders exceeding $99.
