7.2 Using Component video with the system
The
611T
and
611R
system is designed to transfer a Composite video signal. The wide bandwidth of the system
allows transfer of Component video signals by using multiple sets of machines. Two sets can be used to transfer
s–Video signals (Y and C) and three sets can be used to transfer Component video (Y, U, V). In each case the
cable lengths of all the signals involved (video cables and the optic fibers) should be of equal lengths.
Adjustment, if needed, may be done as explained above.
8 ADDING AUDIO TO THE SYSTEM
Although the 611T and 611R pair is designed to carry video signals, audio may be added to the system. The
Kramer VA-11 and VA-12 allows combining and separating two stereo audio signals and a video signal to and
from one coaxial connector. The VA-11 combines two audio channels (stereo) and a video signal to a
“MIXED” output. This mixed signal may be fed into a 611T transmitter, transferred over a long distance and
recovered via the 611R receiver. The recovered “MIXED” signal may be fed into a VA-12, which will separate
the signal into its audio and video components.
Other signals, such as low frequency data signals and so on, may be used instead of one or both audio channels.
The 611T/611R set may be used for digital audio (AES/EBU) transmission instead of Composite video.
9 TYPICAL APPLICATION
A typical application, which is self-explanatory, is described below in Figure 3:

10 TAKING CARE of YOUR FIBER OPTIC DEVICES
Do not locate your device in an environment where it is susceptible to dust or moisture. Both of these may
damage the electronics, and cause erratic operation or failure. Do not locate your device where temperature and
humidity may be excessive. The fiber optic transmitting and receiving chips are very sensitive to heat. Doing so
may also damage the electronics, and cause erratic operation or failure of your machine. Do not clean your
machine with abrasives or strong cleaners. Doing so may remove or damage the finish, or may allow moisture to
build up. Take care not to allow dust or particles to build up inside unused or open connectors.
