The JBX02181 1000BASE-BX40-D SFP Transceiver represents a sophisticated solution for long-distance, single-mode fiber optic networking. Engineered to Fortinet FR-TRAN-BX40-D53 specifications, this optical transceiver delivers exceptional performance in demanding enterprise and carrier-grade environments. **Extended-Range Capabilities** With support for 40-kilometer transmission distances over standard single-mode fiber (9/125 core), this transceiver enables cost-effective long-distance network deployments without requiring expensive exotic fiber types. The bidirectional (BiDi) architecture utilizes wavelength division multiplexing, transmitting at 1550nm and receiving at 1310nm (or vice versa) on a single simplex fiber strand. **Superior Connector Design** The simplex LC/UPC connector provides industry-standard connectivity with low-loss optical coupling. The UPC (Ultra Physical Contact) polish ensures minimal reflectance and superior signal integrity, critical for maintaining link quality over extended distances. **Industrial-Grade Durability** Rated for operation across -40°C to +85°C temperature ranges, this module performs reliably in challenging environments from data centers to remote field deployments. The metal-case construction with integrated laser transmitter provides electromagnetic shielding and thermal stability. **Compliance & Safety** Fully certified to SFF-8472 standards and qualified as an extended-reach BiDi module beyond standard IEEE 802.3ah specifications. Class 1 laser safety certification (21CFR 1040.10), TUV, UL, and FDA approval ensure safe operation. RoHS and ELV directive compliance (EU 2002/95/EC) guarantees environmental responsibility. **Seamless Integration** Drop-in compatible with Fortinet infrastructure, this transceiver simplifies deployment and reduces integration complexity. Custom brand programming is available for OEM and integration partners. **Perfect For:** - Long-distance metro and regional network links - Carrier-grade optical infrastructure - Enterprise WAN interconnections - Remote site connectivity - Fiber optic backbone upgrades Ships from domestic US locations (Danville, CA and Beaufort, SC) with free standard shipping on orders exceeding $99. The 90-day limited warranty provides peace of mind for critical network deployments.
