I just bought a two new linksys switches and two GBIC fiber modules. The orginal switches I am replacing had Multimode SC connectors. The fiber patch box mounted to the wall has ST connectors. So it orginally had a ST to SC fiber patch cable to connect them. I bought two new patch cables for the new equipment that goes from ST to LC connectors. The new fiber modules are Gigabit. I have tried everything I know to try the only thing I can think of is the new patch cables to convert the connectors have the wrong type of size of fiber cable ?
