The JBX02152 1000BASE-BX20-D SFP Transceiver Module represents cutting-edge optical networking technology designed for demanding telecommunications and enterprise applications. This extended-reach bidirectional (BiDi) transceiver goes beyond standard IEEE 802.3ah specifications to deliver exceptional performance over single-mode fiber infrastructure. **Technical Specifications:** This module operates at 1 Gigabit per second with a transmission distance of 20 kilometers over 9/125 singlemode fiber. The simplex LC/UPC fiber connector ensures secure, reliable connections with minimal signal loss. The compact form factor (5x4x2 dimensions) integrates seamlessly into standard SFP slots on compatible network equipment. **Performance & Reliability:** Built with a robust metal case and integrated laser transmitter, the JBX02152 delivers consistent performance across a wide operating temperature range from -40°C to 85°C. This makes it suitable for both climate-controlled data centers and field deployments in challenging environments. **Compliance & Safety:** Fully certified to meet international standards including SFF-8472 specifications, RoHS/ELV directives, and featuring Class 1 Laser safety certification with TUV and FDA approval. These certifications ensure the module meets stringent industry requirements for safety and environmental responsibility. **Compatibility & Applications:** Direct replacement for Brocade E1MG-BXD20-T modules, this transceiver is ideal for network professionals upgrading or expanding Brocade-based infrastructure. Applications include metropolitan area networks (MANs), campus network interconnections, disaster recovery sites, and high-speed data center linking. **Value Proposition:** Offering cost-effective extended-reach connectivity without compromising on quality or performance, the JBX02152 delivers professional-grade optical transmission at competitive pricing. Custom brand programming is available for OEM applications, and free standard shipping on orders over $99 makes it an economical choice for bulk purchases. **Care & Maintenance:** Protect the LC/UPC connectors from dust and contamination when not in use. Store in cool, dry conditions and handle with care to prevent fiber damage. The module requires no special maintenance beyond standard optical equipment care practices.
