INSTALLATION AND OPERATION MANUAL
FIGURE 11 – EXAMPLE SYSTEM IN LINEAR TOPOLOGY
A
The figure below shows a system with FVT/FVR1010SHR units connected in a linear topology. The system demonstrates a video distribution application.
A single video input is transmitted by a FVT1010SHR over fiber optic cable to three daisy-chained FVR1010SHR units. The last unit in the chain is
connected to an audible alarm to indicate faults.
Three receivers are used in this example, but there is no limit to the number of receivers used in a system. This example could also be expanded to
distribute four or eight channels of video using FVT/FVR4014SHR or FVT/FVR8018SHR units, respectively.

The table below shows the SHR configuration switches for each unit in the system. once the system is configured, all of the PoWER, oPTIC and VIdEo
lEds will be solid green except for the oPTIC A lEd on Unit 1 and the oPTIC b lEd on Unit 4, which would both be solid red. No faults will be reported
because RFl has been disabled at Units 1 and Unit 4. The alarm relay will be closed.

let's consider how the system would respond to a broken fiber between Units 2 and 3:

The video would no longer be displayed at Units 3 and 4 because this is system has a linear topology (i.e. there is no redundant fiber path).
The alarm relay will open and cause the audible alarm at Unit 4 to sound. In addition, the other units in the system would indicate the location of the
fault using their oPTIC lEds as described in the table below.
