Cisco 100BASE-LX10 Rugged SFP for Fast Ethernet SFP Ports

The Cisco 100BASE-LX10 Rugged SFP for Fast Ethernet SFP Ports delivers dependable, long-range fiber connectivity for Cisco switches and routers, even in demanding environments. Engineered to handle ordinary single-mode fiber (SMF) links up to 10 kilometers, these SFP modules empower robust uplinks across campuses, distribution rings, or industrial sites. Available in two configurations—the GLC-FE-100LX and the GLC-FE-100LX-RGD—this family gives you flexible options for Fast Ethernet or dual-rate Fast/Gigabit deployments while preserving Cisco reliability, compatibility, and plug-and-play simplicity.

• Long-range 100BASE-LX10 operation: 1310 nm laser on ordinary single-mode fiber supports distances of up to 10 km, enabling scalable networks without the need for extra repeaters or amplifiers.
• Two module configurations for varied environments: GLC-FE-100LX for standard Fast Ethernet deployments and GLC-FE-100LX-RGD for rugged or demanding settings. Both versions share the same Cisco SFP footprint and compatibility with Cisco switches and routers.
• Rugged, professional design for harsh environments: built to withstand challenging conditions typical of industrial, outdoor, or distribution-center deployments, while maintaining reliable fiber performance in a compact SFP form factor.
• Plug-and-play compatibility with Cisco devices: hot-swappable, supports the IEEE 802.3u 100BASE-LX standard, and works seamlessly with Cisco Fast Ethernet or dual-rate Fast/Gigabit ports across a wide range of Cisco switches and routers.
• Energy-efficient and dependable performance: optimized for stable 100 Mbps operation with minimal power impact, delivering consistent throughput and reliable links for critical network applications.

How to install Cisco 100BASE-LX10 Rugged SFP for Fast Ethernet SFP Ports

Follow these steps to install the SFP module in a Cisco switch or router and establish a reliable Fast Ethernet fiber link.

• Power down or place the target port in a safe state according to your maintenance policy before inserting the SFP to minimize ESD risk.
• Insert the SFP firmly into the available SFP slot until it seats with a decisive click, ensuring a secure mechanical connection.
• Connect the fiber cable: use LC duplex single-mode fiber, ensuring proper transmit/receive orientation and clean, dust-free connectors for optimal optical performance.
• Power up the device (or re-enable the port) and verify link status with the device’s management interface; an active link indicator confirms a successful connection.
• Configure the port for 100BASE-LX10 operation or enable auto-negotiation as supported by the device, then test the link with a network tester to confirm throughput and stability across the 10 km link.

Frequently asked questions

• What networks is the Cisco 100BASE-LX10 SFP suitable for? It is designed for Fast Ethernet networks requiring long-range SMF links, such as campus backbones, distribution layers, and industrial sites where reliable 100 Mbps connectivity over fiber is needed.
• What is the maximum fiber distance? The 100BASE-LX10 module supports up to 10 kilometers on ordinary single-mode fiber, enabling large-scale inter-building or outdoor links without additional amplification.
• Which Cisco devices support these SFPs? The modules are compatible with Cisco switches and routers that feature compatible SFP ports for Fast Ethernet or dual-rate Fast/Gigabit operation, following the 100BASE-LX10 standard and Cisco’s SFP ecosystem.
• Are there two versions available? Yes. The GLC-FE-100LX is the standard Fast Ethernet version, and the GLC-FE-100LX-RGD is the rugged variant designed for harsher environments while maintaining the same optical performance and footprint.
• What connectors are used? The modules use standard LC duplex fiber connectors compatible with SMF fiber cables commonly deployed for 100BASE-LX10 networks.
