Cisco Meraki MA-QSFP-100G-LR4-AO 100G QSFP28 LC

Keep high-speed links open across longer runs without changing the network design. The AddOn Networks MA-QSFP-100G-LR4-AO is built for Cisco Meraki environments that need 100 GbE connectivity over single-mode fiber with LC duplex termination. Its LR4 optical design supports long-reach transport at 1310 nm, making it a practical fit for aggregation layers, data center interconnects, and campus backbones where shorter-reach optics would force closer placement of equipment. This module is aimed at teams that need predictable 100 GbE performance and clean interoperability in Meraki-compatible deployments. The QSFP28 form factor keeps density high in modern switches, while the LR4 specification supports the kind of reach required when racks, rooms, or buildings are separated by distance. For infrastructure teams, that means fewer compromises in topology and fewer constraints on where critical gear can live. Choose this optic when the link budget matters and the cost of a failed uplink is higher than the cost of the module itself. It is a focused component for production networks that need long-reach 100G transport with a familiar LC interface and single-mode fiber architecture.
