Keep extended fiber links stable with a TAA-compliant 25GBASE-ER SFP28 designed for enterprise environments that need distance without sacrificing throughput. The AddOn Networks SFP-25G-ER-AR-I-AO is built for Arista-compatible deployments and supports 25 GbE transport over single-mode fiber using an LC duplex interface and 1550 nm optics. This module fits the needs of teams extending connectivity between buildings, across campus backbones, or into remote network rooms where standard short-reach optics fall short. Its ER-class reach gives architects more room to design around real-world fiber paths, patch panels, and distribution frames while preserving a clean 25 GbE handoff. For procurement teams, the value is straightforward: a compatible, TAA-compliant transceiver that supports long-distance enterprise links without pushing you into overbuilt transport gear. For operations teams, it means fewer compromises when the network design calls for distance, consistency, and vendor-aligned interoperability.
