The JBX02157 1000BASE-BX20 SFP Transceiver is a high-performance optical module designed for critical network infrastructure requiring extended-reach single-mode fiber connectivity. This industrial-grade component delivers gigabit speeds (1GB data rate) over impressive 20km distances, making it ideal for campus networks, metropolitan area networks (MANs), and long-distance point-to-point connections. Key Technical Specifications: This simplex transceiver operates using 1310/1490nm wavelengths and qualifies to SFF-8472 extended-reach BiDi standards, exceeding standard IEEE 802.3ah requirements. The 9/125 single-mode fiber core ensures signal integrity and minimal attenuation over extended distances. Its compact form factor (5x4x2 inches) integrates seamlessly into standard SFP slots found in network switches, routers, and optical transport equipment. Features & Benefits: The LC/UPC simplex connector provides secure, low-loss fiber coupling. Its metal case construction with integrated laser transmitter ensures durability in demanding environments. With a wide operating temperature range of -40 to 85°C (-40 to 185°F), this transceiver performs reliably in both indoor data centers and outdoor installations. Compliance & Compatibility: Fully RoHS/ELV compliant and certified to Class 1 Laser standards (LN #50 7/2001), this module meets stringent international safety requirements. It is fully backward compatible with Brocade E1MG-BXU20-T modules, allowing direct OEM part replacement without system modifications. Applications: Perfect for telecommunications carriers, enterprise networks, universities, financial institutions, and government agencies requiring long-distance fiber optic links with guaranteed performance. Custom brand programming is available for OEM requirements. Warranty & Support: Included 90-day limited warranty with flexible shipping options from multiple US distribution centers (Danville, CA and Beaufort, SC). Manufactured to exacting standards in Vietnam and China with full quality assurance documentation.
