Cisco GLC-FE-100LX SFP 100Base-LX10

Keep Fast Ethernet links stable across longer fiber runs with the Cisco 100BASE-LX10 SFP. Built for optical networking and data networking environments, this hot-swappable transceiver installs into a compatible port or slot and connects through an LC duplex interface. It supports 100Base-LX10 over single-mode optical fiber, delivering up to 100 Mbps for access-layer connectivity where predictable performance matters. This module fits Cisco Catalyst 6500 Series, Catalyst 4500 Series, Cisco ME 3400, Catalyst 2960 Series, and Cisco ME 2400 platforms, making it a straightforward replacement or expansion option for established network environments. The single-mode fiber design helps preserve signal integrity over longer distances than copper-based alternatives, while the hot-swappable form factor reduces maintenance disruption during service windows. For teams maintaining legacy Fast Ethernet infrastructure, this SFP offers a clean way to extend or restore optical links without changing the surrounding architecture. It is a focused component for environments that value compatibility, serviceability, and consistent network behavior over broad feature sets.
