AddOn Cisco ONS-SI-100-FX-AO 100BASE-FX SFP Transceiver | TAA Compliant — ONS-SI-100-FX-AO

Keep Fast Ethernet fiber links active with a TAA-compliant SFP designed for Cisco ONS-SI-100-FX compatibility. This AddOn transceiver supports 100BASE-FX operation over multimode fiber, making it a straightforward choice for access-layer connections, legacy switches, and installed network segments that still depend on 100 Mbps optics. For infrastructure teams, the value is precision: match the required form factor, preserve interoperability expectations, and avoid unnecessary platform changes. In environments where the network edge is stable but not yet ready for a full refresh, the right transceiver can extend the life of existing hardware while keeping procurement aligned with compliance requirements. AddOn’s compatibility-focused approach is useful when you need a replacement or expansion optic that fits the original deployment model. It helps maintain service continuity in fiber-connected closets, branch links, and industrial or campus segments where Fast Ethernet remains in use. If your priority is dependable connectivity on a known platform, this module keeps the path clear without adding complexity. Ideal For Replacing a failed Cisco-compatible Fast Ethernet SFP in an existing switch Maintaining multimode fiber links in a branch or campus access closet Supporting compliance-based procurement for government or regulated environments Extending the service life of legacy 100 Mbps optical infrastructure Why This Product 1 Built for 100BASE-FX rather than higher-speed Gigabit optics 2 Cisco compatibility targets installed ONS-SI-100-FX environments 3 TAA compliance supports regulated procurement requirements 4 Multimode fiber support fits legacy access-layer links
