The JBX02180 is a professional-grade 1000BASE-BX40-D SFP transceiver module engineered for organizations requiring extended-reach fiber optic connectivity. This module exemplifies advanced BiDi (bidirectional) technology, enabling simultaneous transmission and reception over a single fiber strand—eliminating the need for duplex fiber installations and reducing infrastructure costs. Key Technical Specifications: This transceiver operates at 1310nm for transmission and 1550nm for reception (or vice versa), providing 1Gbps data rates across distances up to 40 kilometers. The 9/125 micron single-mode fiber compatibility ensures compatibility with standard carrier-grade fiber infrastructure. The simplex LC/UPC connector design offers reliable, low-loss connections with minimal back-reflection, maintaining signal integrity across extended distances. Performance & Reliability: Fully qualified to SFF-8472 extended-reach BiDi specifications, this module exceeds standard IEEE 802.3ah requirements. The metal case with integrated laser transmitter provides exceptional durability and thermal management. Multiple safety certifications—including Class 1 Laser safety, TUV, UL, and FDA 21CFR 1040.10 compliance—guarantee safe operation in professional environments. Applications & Use Cases: Ideal for metropolitan area networks (MANs), inter-office building connectivity, and ISP backbone networks. The 40km reach enables cost-effective network expansion without repeaters or amplification equipment. Perfect for organizations seeking reliable, standards-compliant BiDi solutions that directly replace Cisco GLC-BX53-D40 modules. Compliance & Support: Fully RoHS and ELV compliant, meeting EU Directive 2002/95/EC standards. Backed by a 90-day limited warranty and available with custom brand programming for OEM integrations. Compatible with major network equipment manufacturers including Cisco systems. Ships quickly from domestic warehouses with free standard shipping on orders exceeding $99.
