SKU:GLC-GE-100FX
Naming Breakdown
-
GLC: Gigabit Small Form-Factor Pluggable Transceiver
-
GE: Designed to plug intoGigabit Ethernet SFP ports
-
100FX: 100Mbps Fast Ethernet, 100BASE-FX over multimode fiber
Core Product Positioning
The Cisco GLC-GE-100FX is a hot‑swappable SFP transceiver compliant with IEEE 802.3 100BASE-FX. It enables100 Mbps full-duplex Fast Ethernet connectivitywhen inserted into standard Gigabit Ethernet SFP slots on Cisco switches and routers. It works over legacy multimode fiber infrastructure, delivering a cost-effective method to extend Fast Ethernet fiber links while reusing existing Gigabit SFP ports. It supports SGMII auto-rate negotiation and serves as an investment-protection solution for gradual migration to Gigabit Ethernet.
2. Hardware & Software Compatibility
Supported Host Platforms
Cisco Catalyst 2960, 3560, 3650, 3750, 3850, 4500, 6500, 6800, 9200, 9300; ISR 1100/4000 Series; ASR 1000; Wireless Controllers; Firepower appliances equipped with Gigabit SFP ports.
Supported IOS / IOS XE Versions
All mainstream Cisco IOS and IOS XE releases supporting SFP auto-sensing and 100BASE-FX rate adaptation.
Supported Fiber Type
Multimode Fiber (OM1 / OM2, 62.5/50μm) only; incompatible with single-mode fiber
Unsupported Platforms
Fast-Ethernet-only SFP slots (use GLC-FE-100FX instead), SFP+/SFP28/QSFP ports without adapters, MDS Storage Switches.
Critical Note:GLC-GE-100FX only runs at 100Mbps; it cannot operate at 1Gbps.
