GLC-GE-100FX Use Case
Enterprise Campus Fiber Uplink with GLC-GE-100FX-100FX SFP on GE Ports
In a multi-building corporate campus, IT teams deploy GLC-GE-100FX-100FX SFP modules on GE switch uplinks to span 2 km of duplex multimode fiber between core and access layers. This plug-and-play solution delivers reliable 100 Mbps bandwidth for VoIP, video conferencing, and cloud services, streamlines maintenance with hot-swappable transceivers, and minimizes downtime through predictable plug-and-play performance.
Industrial Automation Networking in Electromagnetically Noisy Facilities
A manufacturing plant integrates GLC-GE-100FX-100FX SFPs on GE Ethernet ports to connect PLCs, SCADA nodes, and HMIs across production lines where EMI and ground loops threaten copper links. The fiber-based 100FX link guarantees total immunity to electrical noise, ensures deterministic packet delivery for real-time control, and extends network reach up to 10 km—driving higher equipment uptime, operational safety, and compliance with industrial standards.
Telecom Metro-Ring Aggregation for 100BASE-FX Subscriber Services
A regional service provider builds a resilient metro ring by equipping GE aggregation switches with GLC-GE-100FX-100FX SFPs to carry 100 Mbps customer circuits over single-mode fiber. The modules support rapid ring protection switching (sub-50 ms failover), seamless integration with legacy 100BASE-FX CPE, and cost-efficient scaling of subscriber bandwidth. The result: improved network availability, simplified fiber management, and accelerated service deployment for enterprise and SMB customers.
