Cisco GLC-FE-100LX-RGD
100BASE-LX SFP for FE port, Original Cisco
Product Highlights
Industrial and outdoor network environments demand optics that can withstand temperature extremes, vibration, and harsh conditions — yet still deliver dependable connectivity. The Cisco GLC-FE-100LX-RGD is a ruggedized 100BASE-LX10 SFP transceiver module engineered to meet exactly that challenge.
This original Cisco SFP provides 100Mbps Fast Ethernet connectivity over single-mode fiber (SMF) at a 1310nm wavelength, supporting link spans of up to 10 km. Its industrial-grade temperature rating of -40°C to 85°C makes it ideal for deployments in manufacturing plants, substations, transportation infrastructure, and other demanding environments where standard commercial-grade optics would fail.
The GLC-FE-100LX-RGD is designed to operate in Fast Ethernet or dual-rate Fast/Gigabit Ethernet SFP ports on Cisco Industrial Ethernet and SmartGrid switches and routers. It is hot-swappable, supports the Cisco quality identification feature, and is interchangeable with other 100BASE-X SFPs on the same line card — giving network teams the flexibility to scale connectivity on a pay-as-you-populate basis without service interruption.
Features & Benefits
Ruggedized Industrial Design
The RGD designation signals an industrial-grade SFP built for extreme operating conditions. With a -40°C to 85°C temperature range, this module is engineered for outdoor cabinets, utility substations, and factory floors where commercial-grade optics cannot survive. Deploy with confidence in environments that would compromise standard transceivers.
100BASE-LX10 Single-Mode Fiber Performance
Operating at 1310nm over single-mode fiber, the GLC-FE-100LX-RGD supports link distances of up to 10 km — ideal for connecting buildings across a campus or linking remote industrial sites back to a central aggregation point. The 100BASE-LX10 standard ensures interoperability with any compliant 100BASE-LX10 interface on the far end.
Hot-Swappable & Pay-As-You-Populate
Install or replace the SFP module without powering down or rebooting the host device. This hot-swap capability minimizes downtime during maintenance windows. The pay-as-you-populate model lets you add SFPs only as ports are needed, optimizing your capital expenditure.
Cisco Quality ID Feature
The GLC-FE-100LX-RGD supports Cisco's quality identification feature, enabling the host switch or router to verify it as a Cisco-qualified SFP. This ensures seamless integration and avoids compatibility warnings that can occur with unqualified third-party optics.
Deployment Scenarios
Industrial Ethernet & Manufacturing Plants
Connect Cisco IE2000, IE3000, or IE3010 series switches across factory floors and production lines. The rugged temperature rating ensures reliable operation in environments with extreme heat, cold, or temperature fluctuations common in manufacturing facilities.
Utility & SmartGrid Infrastructure
Deploy in Cisco Connected Grid switches and routers at electrical substations, water treatment plants, or along distribution networks. The industrial-grade design withstands the harsh outdoor conditions typical of utility infrastructure while providing 10 km fiber reach between sites.
Transportation & Outdoor Campus Networks
Ideal for connecting roadside cabinets, rail-side equipment enclosures, or outdoor surveillance infrastructure back to a central network. The extended temperature range and single-mode fiber reach make it well-suited for geographically distributed outdoor deployments.

Frequently Asked Questions
| Part Number | Product | Key Difference |
|---|---|---|
| GLC-FE-100LX | Cisco 100BASE-LX10 SFP (Standard) | Same 100BASE-LX10 optics and 10 km reach but rated for extended temperature (-5°C to 85°C) — not industrial-grade like the RGD variant. |
| GLC-FE-100FX-RGD | Cisco 100BASE-FX Rugged SFP | Rugged industrial SFP using multi-mode fiber (MMF) with a shorter 2 km reach — choose when MMF infrastructure is already in place. |
| GLC-FE-100EX | Cisco 100BASE-EX SFP | Extended-reach 100BASE SFP supporting up to 40 km over SMF — ideal when distances exceed the 10 km limit of the LX10 module. |
| GLC-FE-100ZX | Cisco 100BASE-ZX SFP | Ultra-long-reach 100BASE SFP supporting up to 80 km over SMF at 1550 nm — for metro or long-haul Fast Ethernet links. |
