Cisco Catalyst 4000 Catalyst 4500 48-Port 100BASE-FX Ethernet Module – WS-X4148-FX-MT

Cisco WS-X4148-FX-MT 48-Port 100BASE-FX Ethernet Module

Expand fiber-based access connectivity in a compatible Cisco Catalyst 4000 or Catalyst 4500 environment with the WS-X4148-FX-MT Ethernet module. This 48-port module is specified for 100BASE-FX Ethernet, giving network teams a high-density fiber interface option for legacy campus, enterprise, and equipment-room deployments. It is suited to replacement planning, network maintenance, and infrastructure projects where the installed chassis requires a matching 100BASE-FX module rather than a newer copper or high-speed interface. Confirm the host chassis, slot, fiber type, connectors, and platform support before installation.
