AddOn Networks QSFP-4X10G-LR-S-AO 10G LR SFP | QSFP Modules, TAA — QSFP-4X10G-LR-S-AO

Keep long-reach Ethernet links stable with a Cisco-compatible QSFP transceiver designed for 10 GbE deployments over single-mode fiber. The QSFP-4X10G-LR-S-AO is built for teams that need predictable optical performance in access, aggregation, and data center environments where downtime is expensive and compatibility matters. This module supports long-distance connectivity at 10 Gbps and is intended for infrastructure that depends on clean handoffs between switches, routers, and optical transport paths. Its LR design targets single-mode runs, making it a practical fit for campus backbones, inter-building links, and rack-to-rack connections that exceed the limits of short-reach optics. For procurement teams, the value is straightforward: a compatible replacement optic that preserves network design intent without forcing a platform change. For operations teams, the benefit is consistency. You get a transceiver that fits into established Cisco-based environments and supports the kind of deterministic performance expected in production networks. TAA compliance adds another layer of fit for public sector and regulated purchasing environments. When the requirement is to maintain service levels while controlling sourcing risk, this module delivers the right balance of reach, compatibility, and deployment confidence.
