The JBX02165 1000BASE-BX40-D SFP optical transceiver represents a professional-grade solution for extended-reach gigabit network applications. This simplex, single-mode fiber (SMF) module delivers impressive 40km transmission distance—doubling standard SFP capabilities—making it ideal for metropolitan area networks, campus connectivity, and industrial facility interconnections. Technical Excellence and Specifications: This transceiver operates at 1GB data rates with bidirectional capability using 1490nm and 1310nm wavelengths. The 9/125 micron single-mode fiber core ensures signal integrity over extended distances while minimizing dispersion. Qualified to SFF-8472 extended-reach BiDi specifications, it exceeds standard IEEE 802.3ah requirements for demanding applications. The LC/UPC simplex connector provides reliable single-strand connectivity with low insertion loss. Industrial-Grade Construction: Manufactured with precision metal casings and integrated laser transmitter components, the JBX02165 withstands harsh operational conditions. Its -40 to 85°C operating temperature range accommodates both indoor data centers and outdoor equipment installations. Class 1 laser certification and TUV/UL/FDA safety approvals ensure workplace safety and regulatory compliance across global markets. Seamless Integration and Compatibility: Fully compatible with Brocade E1MG-BXD40-T systems, this module serves as a drop-in replacement for legacy equipment. The standard SFP form factor integrates with existing network infrastructure without requiring additional hardware modifications. Custom brand programming is available for OEM deployments. Compliance and Reliability: RoHS and ELV directive compliance ensure environmental responsibility. The 90-day limited warranty provides peace of mind, while free standard shipping on orders over $99 reduces total acquisition costs. Ships from US locations in California and South Carolina for rapid deployment. Applications: Ideal for ISP backbone connections, enterprise campus networks, industrial automation systems, and telecommunications infrastructure requiring extended reach without costly fiber multiplication or regeneration equipment.
