Description

The Cisco Catalyst WS-X4748-SFP-E is a high-performance 48-port Gigabit Ethernet SFP line card designed for Cisco Catalyst 4500E Series switches. Built for enterprise, commercial, and service provider environments, this non-blocking line card delivers full line-rate switching to support demanding core and distribution network deployments.

Supporting both 1 Gigabit Ethernet and 100FX SFP transceivers, the WS-X4748-SFP-E allows flexible fiber connectivity using multimode or single-mode optics. It provides 48 Gbps of per-slot switching capacity, ensuring predictable performance for bandwidth-intensive applications such as fiber-to-the-desktop (FTTD), aggregation, and metro Ethernet access.

Advanced features including hardware-based MACsec (IEEE 802.1AE) encryption, Cisco TrustSec, jumbo frame support, and supervisor-engine-driven QoS make this line card a reliable choice for secure, scalable, and high-availability networks. The WS-X4748-SFP-E occupies a single slot and integrates seamlessly into supported Catalyst 4500E chassis.
