# Guidelines for fiber optic cabling

| Make sure that you choose the correct cable for the network that you are connecting to.

| The Ringnode works with a range of different fiber-optic concentrators.

| The maximum number of ringnodes that you can connect on the same STP ring is 250 (assuming that there are no active retiming hub ports on your network).
