The JBX02218 1000BASE-BX80-U SFP transceiver represents an excellent solution for organizations requiring high-capacity, long-distance optical connectivity without the expense of multimode systems or expensive active repeaters. Operating at 1 Gigabit per second, this module delivers robust performance across single-mode fiber networks spanning up to 80 kilometers. Technical Specifications: This bidirectional (BiDi) transceiver utilizes wavelength division multiplexing technology, transmitting at 1550nm and receiving at 1490nm simultaneously through a single fiber strand. The 9/125 micron core single-mode fiber design minimizes dispersion and signal loss, ensuring reliable signal integrity across extended distances. The simplex LC/UPC connector provides low insertion loss and excellent return loss characteristics essential for high-performance networks. Design & Construction: Manufactured with precision metal housings and integrated laser transmitters, the JBX02218 meets rigorous safety and environmental standards. It carries multiple certifications including Class 1 Laser, TUV, UL/FDA compliance (21CFR 1040.10), and adheres to EU RoHS directive 2002/95/EC. The compact SFP form factor (5x4x2mm) ensures compatibility with standard SFP slots on switches, routers, and network interface cards. Compatibility & Integration: Designed as a direct replacement for Cisco GLC-BX-D80 modules, this transceiver integrates seamlessly into existing Cisco infrastructure. Custom brand programming is available for OEM applications and white-label deployments. The module qualifies to SFF-8472 extended-reach BiDi standards, exceeding conventional IEEE 802.3ah specifications. Applications: • Inter-data center connectivity over long distances • Campus network backbone extensions • Remote facility interconnection • Disaster recovery site communications • High-speed WAN acceleration • Service provider metropolitan area networks (MANs) Operational Advantages: With 80km reach capability, organizations eliminate costly repeater infrastructure while maintaining 1GB throughput. The simplex design reduces fiber requirements compared to duplex alternatives. Operating temperature range of 0-70°C provides flexibility for diverse deployment environments. Reliability & Support: Backed by a 90-day limited warranty and qualified to industry standards, this transceiver provides dependable service for enterprise networks.
