Maintain dependable 1 GbE optical connectivity across longer single-mode runs with this AddOn Networks compatible SFP. Tuned for 1310 nm and rated to 10 km, it is suited to access uplinks, inter-building links, and replacement scenarios where the network already expects a 1G LX profile. The LC connector keeps installation familiar for teams working in established fiber plants. This is the kind of module that earns its place in the rack by matching the link requirement exactly. It avoids the mismatch and uncertainty that come with generic optics, especially when you need a replacement that behaves like the original port design expects. For procurement teams, that means a cleaner bill of materials and fewer surprises during deployment. Use it where the network needs a stable, standards-aligned 1 GbE optical path over single-mode fiber. When the distance is measured in kilometers, the wavelength, reach, and connector choice matter as much as the port speed.
