FVT/FVR120D8

12-CHANNEL DIGITALLY ENCODED VIDEO
+ 8 CHANNELS OF BI-DIRECTIONAL DATA

The FVT/FVR120D8 is a twelve (12) channel ten (10) bit digitally encoded video

transmission system. It combines twelve individual video signals into one high speed

digital stream along with eight channels of bi-directional data and transmits this

over one optical fiber. The FVT/FVR120D8 consists of a twelve channel video

transmitter (FVT120D8) and a twelve channel video receiver (FVR120D8). The

first module (A) also transmits and receives eight bi-directional data channels:

RS232, RS422 and RS485 (2W & 4W).

Both the transmitter and receiver are made up from six modules:

1 × 8 Channel Video Module with 8 bi-directional data channels (Module “A”)

1 × 4 Channel Video Modules labeled “B”, “C” and “D”

1 × Passive Optical Wavelength Division Multiplexor (WDM)

1 × Chassis with integral power supply

The outputs of the two (2) Video Modules are combined at the transmitter into a

single optical signal by means of the WDM and separated out at the receiver with an

identical WDM. The video channels are referred to as A1, A2, etc., and B1, B2, etc.

A video input to the A3 transmitter BNC connector will be received out of the A3 BNC

on the corresponding video module.

The FVT120D8 and the FVR120D8 come completely assembled and tested from

the factory. There are no optical or electrical adjustments required or permitted.

However, the DATA CHANNELS must be configured for the specific type of data;

i.e. RS232, RS422 or RS485 2W or 4W. See Figure 5 on Page 5 for specific switch

settings. See Figures 1 – 7 for complete installation instructions.
