The Cisco WS-X6748-SFP Gigabit Ethernet Interface Module is a high-density line card designed for Cisco Catalyst 6500 Series switches and Cisco 7600 Series routers, delivering scalable fiber connectivity for enterprise, campus, data center, and service provider networks. Featuring 48 Gigabit Ethernet SFP ports, the module provides flexible optical networking with support for a wide range of Cisco SFP transceivers.

Designed for high-performance networking environments, the WS-X6748-SFP delivers wire-speed Layer 2 and Layer 3 forwarding, ensuring reliable performance for bandwidth-intensive applications and mission-critical network traffic. It supports centralized Cisco Express Forwarding (CEF) and can be equipped with an optional Distributed Forwarding Card (DFC3), enabling hardware-based distributed forwarding to improve scalability and reduce processing demands on the supervisor engine.

The module supports numerous Cisco Gigabit Ethernet SFP transceivers, including 1000BASE-SX, LX/LH, ZX, BX, CWDM, DWDM, and 1000BASE-T, allowing organizations to deploy copper or fiber connections based on network distance and infrastructure requirements.

Powered by Cisco IOS Software, the WS-X6748-SFP supports advanced enterprise networking features including IPv4, IPv6, IEEE 802.1Q VLANs, inter-VLAN routing, hardware-based Access Control Lists (ACLs), Quality of Service (QoS), multicast, EtherChannel, IEEE 802.3ad LACP, jumbo frames, and Cisco Express Forwarding, depending on the installed supervisor engine and software configuration.

The module features a 40 Gbps switch fabric connection, enabling high-speed communication with the host chassis while maintaining wire-rate forwarding performance. Its hot-swappable modular design simplifies installation, maintenance, and future upgrades without disrupting network operations.

Compatible with Cisco Catalyst 6500 Series chassis and Cisco 7600 Series routers, the Cisco WS-X6748-SFP 48-Port Gigabit Ethernet SFP Interface Module is an ideal solution for expanding high-density fiber connectivity in enterprise and carrier-class environments.

Ideal for enterprise campus networks, data center aggregation, fiber backbone connectivity, service provider infrastructure, metro Ethernet networks, and high-density Gigabit Ethernet deployments, the Cisco WS-X6748-SFP delivers scalable performance, flexible optical connectivity, and enterprise-grade reliability for modern modular network infrastructures.
