Keep 100 GbE links stable with an Arista-compatible QSFP28 transceiver designed for data center interconnects and high-density switching environments. The AddOn Networks QSFP-100G-DR-AR-AO supports 100 Gigabit Ethernet over single-mode fiber with an LC connector, giving infrastructure teams a practical path to extend high-speed connectivity without changing the surrounding optical architecture. This module is suited for teams standardizing on 100G uplinks, spine-leaf fabrics, and switch-to-switch links where port density and optical consistency matter. DOM support helps operations teams monitor link health and optical conditions during deployment and troubleshooting. The DR-class design is aimed at short-reach 100G applications where clean, repeatable performance is more important than overbuying optics for the job. For procurement teams, the value is straightforward: preserve compatibility with Arista environments while sourcing through AddOn Networks for a cost-conscious alternative to OEM optics. That makes this module a strong fit for refresh projects, spare pools, and expansion plans where uptime, fit, and procurement flexibility all matter.
