Maintain reliable 10 GbE connectivity across extended single-mode fiber runs with the ENET SFP-10G-LR-S-ENC. This Cisco SFP-10G-LR-S compatible SFP+ is designed for 10GBASE-LR deployments where link stability, interoperability, and predictable optical performance matter more than commodity pricing. Built for data networking environments, it uses an LC duplex connector and 1310 nm wavelength to support long-distance transmission on single-mode fiber. The LR optical profile is a practical fit for switch-to-switch uplinks, aggregation layers, and cross-rack connectivity where 10 GbE must stay consistent over distance. For infrastructure teams standardizing on Cisco-compatible optics, this module offers a straightforward way to extend ports without changing the network design. It is a focused choice for production fiber links that need the right reach, the right connector, and the right optical class for enterprise use.
