Description

The GLC-FE-100FX is a Fast Ethernet SFP (Small Form-factor Pluggable) transceiver module from Cisco. It is designed specifically for 100BASE-FX fiber-optic connections, providing 100 Mbps network speeds over fiber.

Key Features:

• Form Factor: SFP (Small Form-factor Pluggable).

• Speed: Supports 100 Mbps (Fast Ethernet) speeds.

• Connector Type: LC Duplex connectors for multimode fiber (MMF).

• Wavelength: Operates at a 1310 nm wavelength.

• Transmission Distance:

  • Supports 100BASE-FX connections over multimode fiber (MMF) up to 2 kilometers (1.24 miles), depending on the fiber type and quality.

  • Single-mode fiber (SMF) is not compatible with this module, as it is optimized for multimode fiber.

• Power: Powered directly from the host device through the SFP slot, so no external power supply is required.

• Compliance: Compliant with IEEE 802.3u standards for Fast Ethernet (100BASE-FX).

• Temperature Range: Typically works within the standard commercial temperature range (0°C to 70°C), although specifics can vary based on the Cisco device it’s installed in.

Applications:

• Fast Ethernet (100BASE-FX) Connections: The GLC-FE-100FX is primarily used for 100 Mbps Ethernet fiber-optic connections, commonly seen in older network infrastructures, or in cases where 100 Mbps is sufficient for the network’s bandwidth requirements.

• Multimode Fiber Links: This module is designed for multimode fiber deployments, which makes it ideal for medium-distance connections within data centers, campus networks, or between network devices in the same building.

• Network Upgrades and Legacy Systems: Often used to upgrade older network systems that use 100BASE-FX while still leveraging existing multimode fiber infrastructure. It may also be used in legacy networks where Gigabit Ethernet speeds aren’t necessary.

• Short to Medium Distance Links: Since it supports 100BASE-FX at up to 2 kilometers, it is typically used for inter-building links or other applications where longer fiber connections aren’t required.

Compatibility:

• The GLC-FE-100FX works with Cisco switches and routers that have SFP slots. It is commonly used in Cisco Catalyst series and other Cisco networking equipment.

• It is also compatible with other networking devices that support SFP transceivers (though, as always, it’s best to check compatibility with third-party equipment).
