To connect the fiber port on your JetNet 4005f or JetNet 4008f to another one located on another
JetNet, follow the figure below. Wrong connection will cause fiber ports not to work normally.
JetNet fiber models have two 100Base-FX ports with SC type connectors.

single mode, the connection distance can be up to 30 km.
Fiber segment using multi mode must use 50 or 62.5/125 um multi-mode fiber cables. For single
mode, the connection distance can be up to 2 km.
