Extreme Networks optics are thoroughly tested and are subject to an extensive qualification process before being considered certified to work in Extreme Networks IO modules and switches. Only proven, qualified vendors are chosen to assist in providing an end-to-end optical solution. There is a number of 1000 BASE SFP Optics that are available depending on the customer application and distance capability required. Each optical interface operates and is managed like a fixed port but gives the customer flexibility to hotswap or interchange to different optical module types (i.e., SR, LR, ZR).
