Product Overview

DESCRIPTION

The FX82012 unmanaged Ethernet switch provides one 10BASE-T/100BASE-TX port and two 100BASE-FX fiber ports for the transport of bidirectional Ethernet data. Available in multimode and single-mode versions, the fiber ports use wavelength division multiplexing (WDM), which allows bidirectional data to be transported in a single fiber.

The FX82012 switch can be used in point-to-point and drop-and-repeat applications:

•In a point-to-point application, 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. Refer to Figure 1 for an illustration of a point-to-point application using fiber redundancy.

•In a drop-and-repeat application, two fiber ports allow one or more Ethernet devices to be connected into a fiber optic daisy chain. Refer to Figure 2 for an illustration of a sample drop- and-repeat application.
