The JBX02115 1000BASE-BX10-D SFP transceiver represents a premium solution for organizations seeking reliable, long-distance optical connectivity without premium pricing. This compact single-form-factor pluggable (SFP) module integrates seamlessly into existing network infrastructure while delivering exceptional performance over extended distances. **Technical Specifications & Performance** Designed to IEEE 802.3ah standards, this transceiver operates at 1Gbps data rates with impressive reach—10 kilometers over single-mode fiber (SMF). The 9/125-micron core fiber specification ensures minimal signal degradation and optimal performance in long-distance applications. Operating temperature range of 0-70°C accommodates diverse deployment environments from climate-controlled data centers to outdoor installations. **Architecture & Compatibility** The simplex LC/UPC configuration employs wavelength division—transmitting at 1550nm while receiving at 1310nm—enabling full-duplex communication over a single fiber strand. This innovative approach significantly reduces infrastructure costs compared to duplex solutions. Direct compatibility with Cisco GLC-BX53-D modules ensures seamless integration into existing Cisco switch fabric without requiring firmware updates or compatibility testing. **Safety & Compliance** Manufactured with Class 1 laser certification and comprehensive compliance with RoHS, ELV, and EU Directive 2002/95/EC ensures safe, environmentally responsible operation. Multiple certifications including TUV, UL, and FDA 21CFR 1040.10 demonstrate commitment to international safety standards. **Deployment & Support** Available with custom brand programming options for OEM implementations. Backed by a 90-day limited warranty and supported by expedited shipping from dual US locations (California and South Carolina). Ideal for ISP backbone networks, carrier last-mile solutions, campus connectivity, and disaster recovery links requiring cost-effective long-reach capabilities.
