WS-X4248-FE-SFP Cisco Catalyst 4500 48-Ports 100Base-X SFP Fast Ethernet Switch

WS-X4248-FE-SFP Overview

The Cisco WS-X4248-FE-SFP is a high-density switching module for the Catalyst 4500 Series, designed to provide 48 ports of 100Base-X Fast Ethernet through Small Form-Factor Pluggable (SFP) transceivers. Unlike traditional RJ-45 copper-based modules, this card is fiber-oriented, making it ideal for environments that require extended reach, low latency, and secure, interference-free connections. It supports a wide range of SFP modules, allowing flexible media choices such as multimode fiber, single-mode fiber, and other optical transceivers depending on deployment requirements. The module integrates with Catalyst 4500 Supervisor Engines, taking advantage of centralized switching, management, and control while delivering consistent performance across large-scale enterprise networks.
