The JBX02216 1000BASE-BX80-U SFP transceiver represents a cost-effective, high-reliability solution for organizations requiring extended-reach optical connectivity. This module directly replaces the Cisco GLC-BX80-U-I and delivers industry-leading performance for 80km transmission scenarios over single-mode fiber infrastructure. **Technical Excellence** Operating at 1000BASE-BX BiDi standards, this transceiver utilizes dual wavelengths (1490nm transmit/1570nm receive) to enable full-duplex communication over a single fiber strand, reducing installation complexity and fiber counts. The 9/125 core singlemode design minimizes chromatic dispersion, ensuring signal integrity over extended distances. Qualified to SFF-8472 extended-reach specifications, it exceeds standard IEEE 802.3ah requirements. **Reliability & Compliance** Manufactured with precision engineering and rigorous quality control, the transceiver features a robust metal case with integrated laser transmitter. Class 1 laser certification (LN #50 7/2001) ensures maximum safety, while TUV, UL/FDA, and 21CFR 1040.10 certifications guarantee international compliance. Full RoHS/ELV directive adherence (EU 2002/95/EC) supports corporate sustainability initiatives. **Wide Operating Range** Designed for demanding environments, this module operates reliably from -40°C to 85°C (-40°F to 185°F), supporting both indoor data center and outdoor cabinet deployments. The simplex LC/UPC connector provides secure, repeatable connections with minimal back-reflection. **Application Versatility** Perfect for metro area networks (MANs), campus interconnects, and carrier-grade deployments, this transceiver supports bandwidth-intensive applications including VoIP, video surveillance, and data replication. Organizations can standardize on Cisco-compatible modules while reducing procurement costs. **Customer Support** Included 90-day limited warranty and custom brand programming capabilities ensure seamless integration into existing network infrastructure. Backed by free standard shipping on qualifying orders and availability from strategic US distribution centers (Danville, CA and Beaufort, SC).
