The AddOn Cisco Compatible TAA Compliant SFP transceiver delivers reliable 1-Gigabit Ethernet connectivity using Bi-Directional (BiDi) technology over single-mode fiber. This upstream (BXU) module transmits at 1310nm and receives at 1490nm, enabling 1Gbps data transmission over a single fiber strand for distances up to 10km (6.2 miles). The simplex LC connector interface simplifies cabling infrastructure by requiring only one fiber core instead of two. As a TAA Compliant module manufactured in the USA or UK, it meets mandatory procurement requirements for U.S. Federal Government, military, and GSA-schedule projects where hardware origin compliance is strictly regulated. The transceiver features Digital Optical Monitoring (DOM) support for real-time performance tracking of optical power levels and critical parameters. Bi-directional transceivers must be deployed in matched pairs using complementary wavelengths to achieve simultaneous bidirectional communication. Ideal for cost-effective fiber deployments in enterprise networks, campus connectivity, and telecommunications applications requiring medium-reach 1000Base-BX performance.
