Cisco SPA-8X1FE-TX-V2 8-Port Fast Ethernet Shared Port Adapter

The Cisco SPA-8X1FE-TX-V2 is an 8-port Fast Ethernet Shared Port Adapter (SPA) designed to provide reliable Ethernet connectivity for Cisco routers that support the Shared Port Adapter architecture. This interface module enables network administrators to expand router capabilities by adding multiple Fast Ethernet ports for data communication across enterprise and service provider networks.The module provides eight 10/100 Mbps Fast Ethernet interfaces with RJ-45 connectors, supporting standard copper Ethernet connections using twisted-pair cabling. These interfaces are suitable for connecting routers to local network segments, access networks, or aggregation points where Fast Ethernet connectivity is required. The ports support auto-negotiation for speed and duplex settings, allowing flexible integration with a wide range of network devices.

Designed as part of Cisco’s SPA modular interface system, the adapter integrates with compatible Cisco router platforms, allowing administrators to increase port density and network capacity without replacing existing hardware. This modular architecture simplifies network expansion and allows service providers and enterprises to scale their infrastructure according to evolving connectivity requirements.

The SPA-8X1FE-TX-V2 is engineered for dependable performance in enterprise networks, campus infrastructures, and telecommunications environments. Its robust design ensures stable data transmission and long-term reliability in demanding networking conditions. By providing multiple Fast Ethernet interfaces in a single module, the adapter offers an efficient solution for expanding router connectivity while maintaining operational flexibility.
