Cisco Catalyst IE3300 8 GE SFP Fiber Expansion Module | Industrial Ethernet

Add 8 GE SFP fiber ports to Cisco Catalyst IE3300 rugged switches and build out industrial networks that depend on optical connectivity. This expansion module is designed for environments where copper reach is not enough, or where fiber is preferred for electrical isolation, longer distances, and reduced susceptibility to interference. With 1000Base-X support and SFP mini-GBIC slots, the module gives network teams a flexible way to connect uplinks and distributed endpoints across plant floors, utility sites, transportation systems, and other demanding locations. The DIN rail form factor supports compact industrial installations, while the modular design helps preserve the IE3300 platform investment as port requirements grow. Compared with lower-cost alternatives, this module is built for teams that need predictable fiber integration and a consistent Cisco industrial architecture. It is a practical fit when uptime, serviceability, and network design discipline matter more than simply adding ports. For edge networks that must stay connected across distance and noise, it delivers the right kind of expansion.
