The CISCO GLC-GE-100FX is a transceiver module that provides 100BASE-FX connectivity for Gigabit Ethernet ports. Tailored for fiber optic networks, it is designed to support data communication over multimode fiber (MMF) at distances up to 2 kilometers. Operating at a wavelength of 1310 nm, this small form-factor pluggable (SFP) module can be used for extending the reach of Gigabit Ethernet networks, ensuring connectivity in larger buildings or campus environments. Its compatibility with Gigabit Ethernet ports allows network administrators to integrate fiber-based infrastructure with existing copper-based networks seamlessly, enhancing the flexibility and scalability of network designs. The hot-swappable nature facilitates easy installation and upgrades without necessitating network downtime.
