The JBX02164 1000BASE-BX40-D SFP transceiver represents a professional-grade solution for organizations requiring extended-reach optical networking capabilities. Engineered to deliver 1 gigabit per second data rates across 40-kilometer single-mode fiber distances, this module excels in metropolitan area networks, carrier deployments, and large-scale campus interconnections. **Key Technical Features:** This transceiver utilizes bidirectional (BiDi) technology operating at 1490nm transmit and 1310nm receive wavelengths, enabling full-duplex communication over a single fiber strand. The 9/125 micrometer singlemode fiber core specification ensures optimal signal integrity and minimal attenuation over extended distances. Housing a precision laser transmitter in a robust metal case, the module withstands demanding environmental conditions with an operating temperature range of -10 to 85°C. **Compatibility & Standards:** Designed as a direct replacement for Brocade E1MG-BXD40 modules, the JBX02164 integrates seamlessly into existing Brocade infrastructure. Qualified to industry-leading SFF-8472 specifications and exceeding IEEE 802.3ah standards, it guarantees interoperability and performance consistency. The simplex LC/UPC connector provides secure, low-loss connections essential for mission-critical networks. **Compliance & Certifications:** Fully RoHS and ELV compliant, this optical transceiver meets stringent environmental regulations. Class 1 Laser certification combined with TUV and FDA compliance (21CFR 1040.10) ensures safety across diverse deployment scenarios. The device undergoes rigorous testing to SFF-8472 extended-reach BiDi specifications. **Ideal Applications:** Deploy this transceiver for telecommunications infrastructure, ISP backbone networks, data center interconnections, university campuses, and enterprise WAN links.
