Keep legacy fiber links in service with AddOn Allied Telesis AT-2711FX/LC-001 comparable adapter. This fiber adapter is built for 100 Mbps connectivity over multimode fiber, using a single LC port and supporting distances up to 2 km. For teams maintaining access switches, edge closets, or older network segments, that combination delivers the right balance of reach and simplicity. It is a practical choice when you need to replace a failed adapter or preserve compatibility with existing optical infrastructure without redesigning the link. The LC interface keeps termination straightforward, while multimode support aligns with common short- to mid-range enterprise fiber runs. In environments where uptime matters but the application does not require higher-speed optics, this part helps keep the network stable and supportable. AddOn’s comparable approach is aimed at procurement teams that want a functional replacement path with less friction than sourcing original OEM hardware. That makes it useful for spares, refresh projects, and budget-sensitive maintenance where the goal is to restore service quickly and keep the installed base working.
