WHY CHOOSE THIS PRODUCT?

• Organizations choose the Cisco GLC-FE-100LX when they require dependable Fast Ethernet connectivity over long distances using single-mode fiber. It is especially useful in environments where upgrading to Gigabit is not immediately feasible due to cost, compatibility, or infrastructure constraints.
• Compared to short-reach multimode modules, this LX variant enables significantly longer transmission distances, reducing the need for intermediate networking equipment or repeaters. This helps simplify network design and reduce operational overhead.
• From a business standpoint, it delivers strong ROI by extending existing Fast Ethernet investments, supporting phased network upgrades, and maintaining service continuity in hybrid infrastructure environments.
