About This Part
The Huawei Part Number 03021LXK, identified as an AR01WEG4SA 4-Port 1000BASE-SFP-L3 Ethernet WAN Interface Card, is a critical component designed for robust Wide Area Network connectivity. This module integrates seamlessly into compatible Huawei routing platforms, extending their capabilities with high-density Gigabit Ethernet interfaces. Operating at 1000BASE speeds, each of the four ports supports Small Form-Factor Pluggable (SFP) transceivers, offering flexibility for various fiber optic deployments, including multi-mode and single-mode options depending on the chosen SFP. Crucially, its Layer 3 functionality enables advanced routing protocols and IP forwarding directly on the interface, making it suitable for complex network architectures requiring efficient data plane processing and intelligent traffic management. This card is engineered for reliability and performance in demanding B2B environments. This Huawei interface card is typically deployed in enterprise routers, carrier-grade aggregation devices, and data center interconnect solutions to facilitate high-speed WAN links. It serves various industries, including telecommunications operators, Internet Service Providers (ISPs), large enterprises with distributed networks, and government entities requiring secure and scalable connectivity. The 03021LXK solves the challenge of expanding network capacity and providing modular upgrades to existing infrastructure, enabling organizations to connect branch offices, establish peering points, or extend their metropolitan area networks. By offering four independent Gigabit Ethernet ports with Layer 3 intelligence, it empowers network architects to design resilient, high-performance WAN topologies that support increasing data volumes and diverse application requirements.
