GLC-FE-100EX Use Case
Campus Backbone Extension with GLC-FE-100EX for 100BASE-EX Connectivity
In a multi-building enterprise campus, IT architects deploy Cisco GLC-FE-100EX modules to establish a 100BASE-EX fiber link across a 20 km single-mode span. This solution delivers a resilient, low-latency backbone that unifies disparate network segments, reduces packet loss, and simplifies network management. Outcome: Secure, high-availability connectivity between core and distribution switches, supporting mission-critical applications with predictable performance.
Industrial Automation Network in Manufacturing Plants
A manufacturing plant integrates programmable logic controllers (PLCs) and SCADA servers over a harsh-environment fiber network using GLC-FE-100EX 100BASE-EX SFPs. The modules’ single-mode reach up to 40 km and immunity to electromagnetic interference ensure uninterrupted data flow between production cells and central control. Outcome: Increased system uptime, deterministic traffic delivery for real-time monitoring, and streamlined compliance with Industry 4.0 connectivity standards.
Service Provider Edge Aggregation for Last-Mile Fiber
An ISP leverages GLC-FE-100EX transceivers in edge routers to aggregate subscriber traffic from remote DSLAMs over a 15 km fiber span. The 100BASE-EX link offers a cost-effective, easy-to-scale aggregation layer with hot-swap capability and straightforward diagnostics via SFP port monitoring. Outcome: Reduced operational expenses, scalable subscriber growth, and enhanced QoS enforcement for broadband services.

Questions & Answers
What is the Cisco GLC-FE-100EX Fast Ethernet SFP module?
The Cisco GLC-FE-100EX is a 100BASE-EX small form-factor pluggable (SFP) transceiver for Fast Ethernet, providing 100 Mbps connectivity over single-mode fiber up to 40 km.
What type of fiber cable does GLC-FE-100EX require?
The GLC-FE-100EX uses single-mode fiber (SMF) with an SC-to-SC duplex patch cable for optimal 100BASE-EX performance.
What is the maximum link distance of the 100BASE-EX SFP?
The Cisco GLC-FE-100EX supports a maximum link distance of 40 kilometers over single-mode fiber at 1310 nm.
Which wavelength does the GLC-FE-100EX transceiver operate on?
The GLC-FE-100EX operates at a nominal 1310 nm wavelength, optimized for long-reach Fast Ethernet over single-mode fiber.
What connector type is used by the GLC-FE-100EX?
This module uses an SC duplex connector, ensuring secure, low-loss termination for single-mode fiber links.
Which Cisco devices are compatible with GLC-FE-100EX?
The GLC-FE-100EX is compatible with Cisco routers, switches, and aggregation platforms that support standard SFP slots and 100BASE-EX.
Can I hot-swap the Cisco GLC-FE-100EX SFP module?
Yes. The Cisco GLC-FE-100EX is hot-swappable, allowing insertion or removal without powering down the switch or router.
Can I mix 100BASE-EX and 100BASE-FX transceivers in the same link?
No. 100BASE-EX and 100BASE-FX use different fiber types and link budgets; mixing them may prevent link establishment or degrade performance.
How do I install the GLC-FE-100EX SFP in my switch?
Insert the GLC-FE-100EX into an available SFP slot until it clicks, then connect the single-mode SC fiber cable and verify link status LEDs.
