Keep single-mode fiber infrastructure aligned to procurement and performance requirements with the AddOn Alcatel-Lucent Nokia 471880A.101 compatible 1000BASE-LX SFP. Designed for 1 GbE LX deployments, this transceiver uses LC duplex connectivity and is suited to longer-reach fiber runs than SX optics, making it appropriate for campus backbones, building-to-building links, and distribution-layer connections. TAA compliance adds value in environments where sourcing rules are part of the buying decision. For public sector teams, regulated enterprises, and integrators supporting controlled procurement, that matters as much as the optical specification itself. AddOn’s compatibility focus helps keep replacement planning straightforward when the goal is to maintain service on existing Alcatel-Lucent Nokia platforms without changing the network design. This module is a targeted fit for teams that need a dependable 1 GbE optic for single-mode fiber and want to avoid paying for excess capability. It supports the kind of infrastructure decisions that favor continuity, compliance, and predictable lifecycle management over broad feature sets. When the requirement is to restore a port, stock a qualified spare, or complete a standards-based rollout, this SFP delivers a clean match to the job.
