Keep 100 GbE transport stable across longer optical runs with the Axiom QSFP-100G-LR4-AR-AX transceiver. This QSFP28 module is designed for Arista-compatible environments and uses an LC connector for streamlined integration into single-mode optical infrastructure. For teams building or refreshing high-capacity switching fabrics, it provides the link speed needed for aggregation, core, and data center interconnect roles. The LR4 profile is the right fit when short-reach optics are not enough and you need a module intended for longer-distance 100 Gigabit Ethernet connectivity. In practice, that means fewer compromises when extending high-bandwidth links between racks, rooms, or facilities. Axiom’s compatible optics approach helps procurement teams standardize on a lower-friction alternative without giving up the performance profile expected in production networks. This module is especially useful where uptime, compatibility, and predictable optical behavior matter more than price alone. It is a practical choice for Arista-based infrastructure teams that want a verified replacement optic for critical paths and a cleaner path to scaling 100 GbE capacity.
