Cisco MGBLH1 1000 LH Fibre SFP Mini GBIC

This easy-to-install Mini-GBIC (or SFP) module provides a simple way to add Gigabit functionality to your Linksys switch. Gigabit fiber is often used to connect two switches together. The technology used depends on the distance between the two switches. The LH module uses 1310 nanometer wavelength light in multimode or single-mode fiber optic cables, and can achieve distances up to 500 meters or 40 kilometers, depending on the fiber used.
