Cisco GLC-GE-100FX 100BASE-X SFP Pluggable Transceiver Module

Overview

The Cisco GLC-GE-100FX is a Small Form-Factor Pluggable (SFP) transceiver module designed to provide reliable 100 Mbps Fast Ethernet connectivity over multimode fiber. It is intended to extend fiber links on Cisco Catalyst 3750, 3560, and 2970 switches without the need to replace existing hardware. Supporting full-duplex operation, it effectively doubles bandwidth to 200 Mbps, making it suitable for environments that require efficient data transfer such as campus networks and branch offices.

Key features

• Provides a 100 Mbps Fast Ethernet link over multimode fiber for stable and interference-resistant connections
• Equipped with LC duplex connectors to simplify cable management and ensure secure fiber connections
• Hot swappable design allows installation or replacement without powering down the switch, minimizing downtime
• Full-duplex capability supports up to 200 Mbps throughput, enhancing performance for data-intensive tasks
• Complies with IEEE 802.3z standards to ensure compatibility with a wide range of network equipment
• Plug and play setup reduces installation time and lowers operational costs by simplifying deployment

Connectivity and compatibility

This transceiver module integrates seamlessly with Cisco Catalyst 3750, 3560, and 2970 switches, providing a straightforward upgrade path for existing network infrastructures. Its adherence to IEEE 802.3z ensures it works well with other compliant devices, allowing flexible network expansion. The LC duplex connectors support easy fiber cable connections, which are ideal for environments where copper cabling is unsuitable due to interference or distance limitations.

Installation and setup

Installation is simple and efficient: the module slides directly into the SFP slot on compatible switches, and the device immediately recognizes the fiber link once connected. Its hot swappable design means you can add or replace the transceiver without interrupting network services, which is critical for maintaining uptime in business or industrial settings. This plug and play approach reduces the time and complexity typically associated with fiber link upgrades.

Ideal uses and environments

The Cisco GLC-GE-100FX is well suited for campus networks, branch offices, and industrial control rooms where fiber optic cabling is preferred over copper due to distance or electromagnetic interference concerns. It supports departments that require reliable and efficient data transfer for tasks such as large file sharing, data backups, and video streaming. Network administrators looking for a cost-effective fiber solution with Cisco’s trusted management experience will find this module a practical choice.
