The JBX01969 100BASE-BX40 SFP Transceiver is a professional-grade optical module engineered for demanding network environments requiring extended-reach connectivity. This bidirectional single-mode fiber transceiver sets the standard for reliable long-distance data transmission in modern networking infrastructure. Technical Excellence: This transceiver operates on a wavelength division multiplexing (WDM) architecture, utilizing 1550nm for transmission and 1310nm for reception (or vice versa), enabling full-duplex communication over a single fiber strand. The 40km reach capability makes it ideal for metropolitan area networks (MANs), enterprise WAN links, and telecommunications applications where distance is a critical factor. Construction & Compatibility: With its compact SFP form factor and aluminum metal case housing, this module integrates seamlessly into existing infrastructure. It is explicitly designed as a drop-in replacement for Cisco GLC-FE-100BX-D40 transceivers, ensuring plug-and-play compatibility with Cisco networking equipment. The simplex LC/UPC connector provides secure, low-loss connections with industry-standard performance. Compliance & Certification: This transceiver meets stringent international standards including RoHS/ELV directives, ensuring environmental responsibility and regulatory compliance. Class 1 Laser certification and TUV/UL/FDA compliance guarantee operational safety. SFF-8472 qualification ensures interoperability across supported platforms. Applications: • Long-distance campus connectivity • Metropolitan area network (MAN) deployments • ISP backbone infrastructure • Enterprise WAN links • Telecommunications networks • Data center interconnects requiring extended reach Operating Parameters: The module functions reliably within an operating temperature range of 0-70°C (32-158°F), suitable for both indoor and outdoor cabinet installations. Its robust design and laser transmitter components ensure consistent performance across extended deployment periods. Value Proposition: By offering Cisco compatibility at a competitive price point with extended 40km capabilities, this transceiver provides enterprise-grade performance without premium costs. Backed by a 90-day limited warranty and available custom brand programming, it represents a flexible solution for network infrastructure upgrades.
