Keep legacy Fast Ethernet infrastructure online with a 24-pack of Cisco-compatible SFP transceivers built for 100Base-FX links over multi-mode fiber. Each module uses an LC connector and 1,310 nm optics to support up to 2 km of reach, making it a practical fit for access switches, aggregation points, and distributed network closets where dependable short-haul fiber matters. This AddOn transceiver is MSA-compliant, hot-swappable, and designed to meet or exceed OEM expectations for Cisco environments. Every unit is programmed, uniquely serialized, and tested for data traffic and application behavior before shipment, which helps reduce deployment risk when you are standardizing optics across multiple sites. The 24-pack format also supports larger refreshes, spares planning, and consistent optics replacement without mixing vendors or part revisions. For teams managing procurement controls, the TAA designation supports government and regulated purchasing requirements. For operations teams, the lifetime warranty adds long-term coverage to a module class that often sits at the edge of critical connectivity. When you need a cost-effective way to preserve installed fiber infrastructure without compromising compatibility, this pack is built for that job.
