I believe it was around 2004 when we first setup our network. We have four data closets with fiber going between them. Each have three D-Link DSS-24+ switches with 10/100 ethernet. We would like to upgrade to switches with gigabit ethernet but are having a hell of a time finding a variety that use SFP modules. Has this standard gone the way of the Dodo? Should I be look at something else? We don't have the money for anything managed nor do we need it.
