Product Review

The Cisco WS-X4748-SFP-E line card offers 48 SFP ports supporting 1GbE/100Mbps speeds, suitable for diverse enterprise and service provider applications, including GE aggregation and FTTH/FTTB deployments. Its hardware supports IEEE 802.1AE fiber encryption and Cisco TrustSec, enhancing network security, while the ability to support jumbo frames up to 9216 bytes and inherit QoS capability from the Supervisor Engine improves network performance and flexibility. However, the card's maximum power consumption of 75W and requirement for Cisco IOS Software Release IOS-XE3.5.0E/15.2(1)E or later may limit its compatibility and increase operational costs in some environments.


The Cisco WS-X4748-SFP-E is a high-performance line card designed for enterprise, mid-market, and commercial core and distribution deployments, as well as service provider applications. This product provides 48 ports of SFP (Small Form-Factor Pluggable) that support both 1 Gigabit Ethernet and 100 Megabit per second speeds, accommodating a wide range of network demands. It operates with a 1:1 wire rate, ensuring that all ports can run at full capacity simultaneously without any traffic congestion. With a maximum power consumption of 75 Watts, it balances performance and energy efficiency. The Mean Time Between Failures (MTBF) is rated at 876,100 hours, indicating a high level of reliability and durability for sustained operational use. This line card supports up to 48 interfaces per line card, making it an adaptable solution for expanding network infrastructures. The WS-X4748-SFP-E requires Cisco IOS Software Release IOS-XE3.5.0E/15.2(1)E or later for optimal performance, ensuring that the hardware is equipped with the latest features and security measures. It is designed with hardware capability for IEEE 802.1AE fiber encryption and Cisco TrustSec, enhancing network security by providing an additional layer of encryption and identity-based access control. Jumbo frame support up to 9216 bytes is available, facilitating the efficient handling of large data packets and improving overall network performance. The Quality of Service (QoS) capability is inherited from the Supervisor Engine, allowing for the prioritization of network traffic to ensure that critical applications receive the bandwidth they require. The applications of this line card are versatile. For enterprise, mid-market, and commercial sectors, it is ideal for core and distribution deployments requiring line-rate capability. In the service provider space, it serves well for Gigabit Ethernet aggregation from various access devices like DSLAMs, Passive Optical Networks (PON), or mobile data backhauls. Additionally, it is suitable for point-to-point fiber connections to homes (FTTH) or buildings (FTTB), catering to both residential and business applications. Compatibility with multiple chassis types – 3, 6, 7 (R-E & R+E), and 10 (R-E & R+E) Slot – ensures that this line card can be integrated into various network environments, offering flexibility in deployment. Key features include:
  • 48 SFP ports supporting 1GbE/100Mbps speeds.
  • IEEE 802.1AE fiber encryption and Cisco TrustSec capability for enhanced security.
  • Jumbo frame support up to 9216 bytes for improved data transmission efficiency.
Overall, the Cisco WS-X4748-SFP-E line card is a powerful and versatile networking solution that meets the demands of a wide range of deployment scenarios, offering both high performance and enhanced security features to support complex network architectures.
