Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Tested to factory specification. Backed by 25 years of enterprise trust.
The Cisco WS-X4124-FX-MT is a 24-port 100BASE-FX multimode fiber switching module built for the Cisco Catalyst 4000 series platform. Leveraging fiber-optic technology, this module enables Fast Ethernet connectivity at distances that exceed the limitations of copper-based solutions, making it well-suited for intra-building or campus backbone deployments where electromagnetic interference (EMI) is a concern.Operating at 100 Mbps per port over multimode fiber, the WS-X4124-FX-MT supports reliable, full-duplex communication across a 24-port configuration. Its MT-RJ connector interface provides a compact form factor that simplifies cable management in high-density environments. The module integrates seamlessly into the Catalyst 4000 chassis, leveraging the platform's switching fabric and management capabilities.
Sourced as Refurbished hardware, this module undergoes inspection and testing to ensure it meets operational standards, offering significant cost savings compared to new equivalents without compromising network reliability. It is an excellent choice for IT teams managing legacy Catalyst 4000 deployments who need to expand fiber port density or replace failed modules while keeping costs under control.
WhaleyComm stands behind every Refurbished unit we ship, providing enterprise IT teams with confidence in their hardware investment. Whether you are maintaining an existing network or building out a fiber-rich access layer, the WS-X4124-FX-MT delivers proven Cisco performance at a fraction of the original cost.

Ideal Use Cases
Campus Fiber Distribution
Deploy the WS-X4124-FX-MT to connect fiber-cabled workgroups or network closets within a campus environment where copper distance limitations are a concern. Its 24 multimode fiber ports provide ample density for mid-size distribution layer deployments.
EMI-Sensitive Environments
In manufacturing floors, data centers, or industrial facilities where electromagnetic interference can degrade copper cabling performance, fiber-optic connectivity via this module ensures signal integrity. The 100BASE-FX standard provides a stable, noise-immune Fast Ethernet connection.
Legacy Catalyst 4000 Infrastructure Expansion
Organizations maintaining Cisco Catalyst 4000 chassis investments can use the WS-X4124-FX-MT to add or replace fiber switching capacity without requiring a full platform upgrade. This makes it a practical, budget-conscious option for extending the life of existing network infrastructure.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The WS-X4124-FX-MT uses MT-RJ connectors, a compact dual-fiber interface commonly found in high-density fiber switching deployments. Ensure your fiber patch cables or wall plates use MT-RJ connectors for compatibility.
This module supports 100BASE-FX over multimode fiber (MMF). Standard 62.5/125µm or 50/125µm multimode fiber patch cables with MT-RJ connectors are required for proper operation.
The WS-X4124-FX-MT is confirmed for the Catalyst 4000 series platform; compatibility with the Catalyst 4500 series should be verified against Cisco's official hardware compatibility documentation before purchase. Contact WhaleyComm if you need assistance confirming fit for your specific chassis.
Refurbished means this module has been previously deployed and has since been inspected and tested to verify operational functionality. WhaleyComm sources Refurbished Cisco hardware to provide enterprise-grade networking components at a reduced cost compared to new units.
