Equipment Description
The system capable of transmitting and receiving 1 simplex video signal and 2 simplex
or duplex audio channels and 2 simplex or duplex data signals over 1 fiber.
Depending on the distance requirements between sites, the VAD900 Series may be
equipped to operate over multi-mode fiber or equipped to operate over single mode
fiber. Distances between the transmitter and receiver can be up to 10 Km for multimode operation and up to 80 Km for singlemode operation.
The VAD900 system employs uncompressed analog to digital modulation techniques,
which provides for superior receiver output stability and is unaffected by changes in
the fiber path attenuation caused by environmental factors, splicing or aging.
The VAD900T accepts the baseband video signal for transmission via an optical digital
carrier over a single optical fiber. At the distant end, the VAD900R receiver accepts the
optical carrier and converts it to the output video channels.

TROUBLESHOOTING
Troubleshooting is the systematic approach to solving a problem. Each step must be
performed in sequence, or erroneous test results may be obtained.
The VAD900 Series has two optical transmission indicators: LLINK and RLINK. Both
the VAD900T and the VAD900R have these indicators. The LLINK always refers to
the Optical Transmission Status of the
For example, if you are looking at the front panel of the VAD900R and the LLINK is
illuminated GREEN, this indicates that the VAD900R is receiving a valid optical signal.
If the RLINK LED is GREEN, this means that the remote end unit (e.g. VAD900T) has
a valid optical signal. For troubleshooting purposes LOCAL END refers to the unit
with the indicators you are observing and REMOTE END refers to the unit at the other
end of the optical cable.
