The FX82052 unmanaged Ethernet switch provides five 10BASE-T/100BASE-TX ports and two 100BASE-FX 
fiber ports for the transport of bidirectional Ethernet data. The FX82052 switch is available in versions that 
accept one or two multimode or single-mode fibers per fiber port.

The FX82052 switch can be used in point-to-point and drop-and-repeat applications:

•

In point-to-point applications, a second fiber port provides an optional redundant fiber link. 
Using the fiber redundancy option, the second fiber port—which is idle during regular 
operation—becomes operational if the primary fiber port fails.

•

In drop-and-repeat applications, two fiber ports allow one or more Ethernet devices to be 
connected into a fiber optic daisy chain.

Refer to Figure 1 for illustrations of point-to-point and drop-and-repeat applications using FX82052 
versions that accept one fiber per fiber port. Using wavelength division multiplexing (WDM) 
technology, bidirectional data is transported in one fiber.

NOTE: In Figure 1, the FX82052 switch is referred to as the FX82052-2 to represent module versions 
that accept one fiber per port (total of two fibers). For a listing of the exact model names, refer to  
Models on page 10.

Refer to Figure 2 for illustrations of point-to-point and drop-and-repeat applications using FX82052 
versions that accept two fibers per fiber port. Two fibers are required to transport bidirectional data 
over a fiber port.

NOTE: In Figure 2, the FX82052 switch is referred to as the FX82052-4 to represent module versions 
that accept two fibers per port (total of four fibers). For a listing of the exact model names, refer to  
Models on page 10.
