Description

The GLC-GE-100FX is a Gigabit Ethernet transceiver module from Cisco designed for fiber-optic connections. It supports a 100 Mbps (Fast Ethernet) to Gigabit Ethernet transmission over fiber but is optimized for 100BASE-FX applications. It’s typically used for long-distance or high-performance connections in network environments that require fiber connectivity.

Key Features:

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

• Speed: Supports 100 Mbps (Fast Ethernet) and 1 Gbps (Gigabit Ethernet) connections.

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

• Wavelength: Operates typically at 1310 nm for transmission over multimode fiber.

• Transmission Distance:

  • Can transmit data over multimode fiber (MMF) at distances of up to 2 kilometers (1.24 miles), depending on the fiber type and quality.

  • Single-mode fiber (SMF) connections typically don’t apply to this model, as it’s designed primarily for multimode links.

• Power: Powered by the host device through the SFP slot, no external power supply is needed.

• Compliance: Compliant with IEEE 802.3u (Fast Ethernet) and IEEE 802.3z (Gigabit Ethernet) standards.

• Temperature Range: Typically works within the standard commercial temperature range (0°C to 70°C), though exact conditions can vary based on the specific equipment and environment.

Applications:

• Fast Ethernet and Gigabit Ethernet Links: This module is typically used for network connections that require fiber-optic cables but are constrained to 100 Mbps or 1 Gbps speeds. It’s great for network expansions, inter-building connections, and other fiber deployments.

• Multimode Fiber Deployments: The GLC-GE-100FX is optimized for use with multimode fiber, making it ideal for medium-distance applications within a building or campus environment.

• Network Upgrades: Used for upgrading older Fast Ethernet networks to Gigabit Ethernet, providing more bandwidth over existing multimode fiber infrastructure.

Compatibility:

• Cisco switches and routers that have SFP slots can utilize this module. It’s a popular choice for Cisco Catalyst series switches and other Cisco devices.

• It is also compatible with other vendors’ networking equipment that support standard SFP transceivers, although performance and interoperability may vary.
