The DS-2FSM module provides 2 100M single-mode fast Ethernet optical interfaces. The physical
interface is a standard SC optical interface and the single-mode fiber is used whose maximum
transmission distance is 15 km. Two pairs of single-mode fibers are required for it. The fiber length
and peer interface type depend on the real situation.
