Can gigabit and 100 Mbps optical modules be used interchangeably
GLC-GE-100FX is a Cisco SFP module that lets a Gigabit Ethernet port on a Cisco switch or router carry a 100BASE-FX optical link. A standard 1000BASE-SX or 1000BASE-LX SFP cannot simply be configured to run at 100 Mbps because its optical PHY is fixed at 1 Gbps. GLC-GE-100FX exists specifically to. I deal mainly with smaller networks and slower internet speeds (usually 10Mb-100Mb), so my world mainly revolves around 100Mb and 1Gb Ethernet optics. I'm struggling to wrap my head around how there can be SX and LX modules at both 100Mb and 1Gb speeds. What do those designations ("SX" and "LX"). An optical transceiver is a modular component that converts electrical signals into optical signals (and vice versa). Installed in switch or router ports, transceivers enable fiber-based communication between network devices. Key characteristics include: Speed: 1 Gbps, 10 Gbps, 25 Gbps, or higher.
