Support long-distance 10 Gbps connectivity with this 2-pack of single-mode optical modules. Built as duplex SFP+ transceivers, they are designed for single-mode fiber links up to 10 km, making them a practical choice for switch uplinks, inter-building runs, and focused network upgrades. The 2-pack format is ideal when you need a matched pair for a specific link or want to keep a small reserve of identical optics on hand. That matters in enterprise environments where consistency reduces troubleshooting time and helps procurement stay aligned with the installed base. Compared with short-reach optics, this module set gives you the headroom needed for longer fiber paths without changing the network design. It is a straightforward fit for teams that value predictable performance, clean LC duplex integration, and a deployment model that scales from one link to many.
